## Integration guide

The TapHome "Intesis Air Conditioners" template is a Modbus TCP integration designed around the Intesis (HMS Networks) Modbus AC interface family. Its register map aligns 1:1 with the Panasonic PA-AC-MBS-1 (order code `INMBSPAN001I100`) for Panasonic Etherea indoor units, while the base registers (H:0–H:26) also work on the Daikin, Mitsubishi Electric, Fujitsu, Hitachi, LG and Samsung variants of the same gateway family.

The template exposes 32 devices spanning every major control function: on/off, operating mode, fan speed, vertical and horizontal vane positions, a thermostat with current and desired temperature, External Sensor Temperature for the Virtual Temperature mechanism, compressor diagnostics, ECONAVI presence sensing, Demand Response (DRM) levels, min/max setpoint readback, error-code reporting, and Panasonic's Today/Yesterday/Total energy history.

## Hardware connection

### System architecture

![Intesis PA-AC-MBS-1 — up to 63 AC indoor units on EIA-485 bus to the Modbus RTU master](https://taphome.com/images/compatibility/intesis-air-conditioners/system-architecture_hu_7511cc883484f5c9.jpg)

A single PA-AC-MBS-1 / INMBSPAN001I100 interface is dedicated to **one indoor unit** and is powered directly from the AC unit (no external power supply needed). Up to **63 interfaces** can share one EIA-485 bus, each with its own Modbus slave address. The gateway sits between the Panasonic indoor-unit CN-CNT socket and the Modbus RTU master — in this integration, TapHome acts as the master.

### Template transport — Modbus TCP via RTU converter

The XML template declares **Modbus TCP** (`ModbusTcpCCU` with `IpAddress` + `SlaveId`), while the PA-AC-MBS-1 hardware is **Modbus RTU only** (EIA-485, 9600 bps default, 8N2, slave address 1–63). A **Modbus TCP ↔ RTU converter** is therefore required between the TapHome core and the Intesis gateway. Known-working converters:

- **ComWinTop CWT-MB300E** — wired Ethernet to RS-485
- **USR-IOT USR-W630** — Wi-Fi to RS-485, industrial
- **Elfin-EW11** — compact Wi-Fi to RS-485

> [!TIP]
> The **Panasonic VRF variant INMBSPAN016O000** (order code `PA-AC-MBS`, up to 16 indoor units per gateway) supports **Modbus TCP natively** in parallel with RTU. Users with ECOi/PACi VRF installations can connect TapHome directly to it without a converter.

### Connection to the AC indoor unit

![Intesis PA-AC-MBS-1 connection to the Panasonic indoor unit CN-CNT socket and to the EIA-485 bus](https://taphome.com/images/compatibility/intesis-air-conditioners/wiring-connections_hu_7d10d61a446459c8.jpg)

1. Disconnect mains power from the AC unit.
2. Open the indoor-unit front cover to access the electronic circuit.
3. Locate the socket labelled **CN-CNT** on the indoor PCB.
4. Plug the supplied Intesis cable (1.5 m / 4.9 ft fixed length — do not modify) into CN-CNT on one end and into the CN-CNT connector on the INMBSPAN001I100 on the other end. Keep the cable clear of power/ground wiring.
5. The interface can be mounted inside or outside the indoor unit (DIN rail EN60715 TH35 or wall).
6. Connect the EIA-485 terminal block (A/B) to the RS-485 side of the Modbus TCP ↔ RTU converter.
7. Reconnect mains power.

### RS-485 (EIA-485) bus wiring

Use the 2-pole plug-in terminal block on the PA-AC-MBS-1. Respect polarity:

- **A+** on PA-AC-MBS-1 → **A+/D+** on the Modbus TCP/RTU converter
- **B−** on PA-AC-MBS-1 → **B-/D-** on the converter
- Ground the shield on the converter side only (single-point grounding)

**Bus rules:**

- Topology: **linear only** — loop and star are not allowed on EIA-485
- Maximum bus length: **1,200 m** (3,937 ft)
- **120 Ω termination** required at each end of the bus — the PA-AC-MBS-1 includes an internal 120 Ω resistor enabled via DIP switch SW4-P4
- Fail-safe biasing must be supplied by the Modbus master (most industrial converters provide it)
- Up to **63 Intesis interfaces** on the same bus

> [!WARNING]
> The CN-CNT cable length (1.5 m) must not be modified. Keep it away from power/ground wires and do not bundle it with them — proximity to mains wiring can degrade communication with the indoor unit.

## Configuration

### DIP switch layout

![PA-AC-MBS-1 DIP switches SW1, SW3 and SW4 on the device board](https://taphome.com/images/compatibility/intesis-air-conditioners/dip-switch-layout_hu_758f484a948c7d17.jpg)

The PA-AC-MBS-1 has three DIP-switch banks on the board. All DIP changes require a **power cycle** to take effect.

**SW1 — AC indoor-unit features**

| Position | OFF | ON (default) |
|----------|-----|--------------|
| SW1-P1 | Indoor unit has no FAN mode | Indoor unit has FAN mode |
| SW1-P2 | Indoor unit has no horizontal vanes | Indoor unit has horizontal vanes |
| SW1-P3, P4 | Leave at factory default | — |

**SW3 — Modbus slave address (1–63) + part of baud rate**

- Positions P1–P6: binary-coded Modbus slave address. Default = 1 (P1 ON, rest OFF).
- Positions P7–P8: together with SW4-P3 select the baud rate.

**SW4 — Temperature magnitude, baud rate, termination**

| Position | OFF (default) | ON |
|----------|---------------|----|
| SW4-P1 | Temperature in **decicelsius** (×10, e.g. 220 = 22.0 °C) | Temperature in **Celsius ×1** (e.g. 22 = 22 °C) |
| SW4-P2 | Celsius | Fahrenheit |
| SW4-P3 | Baud-rate selector (see table) | — |
| SW4-P4 | EIA-485 bus without internal termination | Internal 120 Ω termination enabled |

> [!WARNING]
> The factory default for SW4-P1 is **OFF = decicelsius (×10)**. TapHome temperature devices in this template expect raw Celsius values, so readings such as `220` instead of `22 °C` indicate the DIP is still at its factory position. Set **SW4-P1 to ON** to switch the gateway to Celsius ×1 (integer °C) before integrating with TapHome, or apply a `÷10` formula in a virtual device for each temperature register (H:4, H:5, H:22, H:24, H:25, H:66). Fahrenheit (SW4-P2 ON) is not supported by this template.

**Baud rate (SW3-P7/P8 + SW4-P3)**

| SW3-P7 | SW3-P8 | SW4-P3 | Baud rate |
|:------:|:------:|:------:|-----------|
| OFF | OFF | OFF | 2400 |
| OFF | ON | OFF | 4800 |
| ON | OFF | OFF | **9600 (default)** |
| ON | ON | OFF | 19200 |
| OFF | OFF | ON | 38400 |
| OFF | ON | ON | 57600 |
| ON | OFF | ON | 76800 |
| ON | ON | ON | 115200 |

### Gateway overview — LED and terminals

![PA-AC-MBS-1 front view — AC unit connection, LED indicator, DIP switches SW1/SW3/SW4, and EIA-485 port](https://taphome.com/images/compatibility/intesis-air-conditioners/device-overview_hu_eb92a1d2a57ab963.jpg)

On the front of the interface:

- **AC Unit connection** (CN-CNT) — top side, goes to the indoor unit
- **LED indicator** — operational status (see table below)
- **SW1** — AC features (next to the AC-unit connector)
- **SW3**, **SW4** — Modbus and extra settings (bottom edge)
- **EIA-485 port** — 2-pole screw terminal A/B (bottom right)

**LED indicator states**

| Device status | LED pattern | Meaning |
|---------------|-------------|---------|
| Power-up | ON for 5 s, then OFF | Device reset / power-up |
| Normal operation | 200 ms ON / 2 s OFF | Gateway correctly configured and communicating |
| Normal operation | Continuously OFF | No Modbus slave address configured |
| Fault | 200 ms ON / 200 ms OFF | Communication error with the AC unit |

### Intesis MAPS configuration software

All settings exposed via DIP switches can alternatively be written through **Intesis MAPS** — a free commissioning tool from HMS Networks. MAPS is also used to update gateway firmware and to scan for connected indoor units on the multi-unit VRF variants. The PA-AC-MBS-1 covered by this template does not require MAPS for basic use; the DIP switches are sufficient for slave address and baud rate.

### TapHome module configuration

In TapHome, configure the module with:

- **IP address** of the Modbus TCP ↔ RTU converter (or the INMBSPAN016O000 VRF gateway when used natively)
- **Slave ID** matching SW3 on the Intesis interface (default 1)

If the converter maps multiple RTU slaves behind a single TCP IP, use the converter's own slave-address translation feature (not the TapHome Slave ID) to select the correct interface on the bus.

## Device capabilities

The template exposes **32 devices** covering the full Panasonic Etherea register set. The base registers (H:0 through H:26, including H:9 Operation Time) are part of the **shared Intesis Modbus AC base layout** and work across all brand variants (Daikin, Mitsubishi Electric, Fujitsu, Hitachi, LG, Samsung). Registers from H:38 upwards are **Panasonic Etherea-specific** and will typically read `0` or `−32768` on non-Panasonic gateways.

### Power and operating mode

- **Power** (H:0) — switches the indoor unit on or off. Base register, works across all Intesis AC brands.
- **Mode** (H:1) — Auto, Heat, Dry, Fan, Cool. Base register, cross-brand.
- **Heat 8/10 °C Mode** (H:56) — Panasonic low-temperature heating (5–8 °C range) for holiday/frost protection. Panasonic Etherea only.
- **Powerful** (H:38) — short-term boost for maximum heating/cooling output. Panasonic Etherea only.
- **Quiet** (H:39) — low-noise operation, reduces outdoor-unit fan speed. Panasonic Etherea only.
- **ECO Mode** (H:57) — ECONAVI energy-saving selector with three states (Off / Econavi / Auto Comfort). Auto Comfort requires 2013 PKE series or newer.
- **Demand Response** (H:58) — DRM level selector (Normal / Comp OFF — DRM1 / 50 % — DRM2 / 75 % — DRM3). Panasonic Etherea only.

### Thermostat and temperature references

- **Thermostat Setpoint** (H:4 desired + H:5 current) — modelled as a TapHome thermostat: the current reference temperature comes from H:5 (typically return-air or remote-sensor reading) and the desired setpoint from H:4. Setpoint range is unified 16–30 °C on Panasonic; on Daikin DK-AC-MBS-1 it is 18–32 °C in cooling and 16–30 °C in heating.
- **Current Max Setpoint** (H:24, read-only) — upper limit currently enforced by the indoor unit (default 30 °C). Base register.
- **Current Min Setpoint** (H:25, read-only) — lower limit currently enforced (default 16 °C). Base register.
- **External Sensor Temperature** (H:22) — feeds a room sensor value into the gateway to activate the **Virtual Temperature** mechanism. When set, the gateway computes the effective setpoint as `SAC = Su − (Tu − TAC)` (Panasonic formula), where `Su` is the Modbus-side setpoint, `Tu` is the external temperature reference and `TAC` is the indoor-unit reference (H:5). Leaving H:22 at the default `−32768` disables the mechanism. When Virtual Temperature is active the Panasonic remote controller can no longer change the setpoint.
- **Return Path Temperature** (H:66, read-only) — temperature on the AC return-air path. Panasonic Etherea only.

### Fan and airflow

- **Fan Speed** (H:2) — Auto plus 5 manual steps (Low → High). Units with fewer available steps silently ignore the unused values. Base register, cross-brand (fan-step count differs per brand — Daikin gateways expose 6 manual speeds plus a Fan Stop code).
- **Vertical Vane Position** (H:3) — Auto, Up, three intermediate positions, Down, Swing. Base register.
- **Horizontal Vane Position** (H:26) — Auto, Left, three intermediate positions, Right. Requires SW1-P2 ON on the PA-AC-MBS-1 (indoor unit must have horizontal vanes). Base register on brands that support horizontal vanes.

### Diagnostics and runtime

- **Error Code** (H:11, read-only) — manufacturer error code. `0` = no error, `65535` (`−1`) = gateway-to-AC communication error, other values follow the manufacturer table (Panasonic uses H/F codes such as `8209` = H11 indoor/outdoor communication error; Daikin gateways return A/C/E/H/J/L/P/U codes).
- **Compressor Status** (H:53, read-only) — Off, To Off (ramping down), To On (ramping up), On. Panasonic only.
- **Compressor On Time** (H:54) — cumulative hours the outdoor compressor has run (0–65 535 h, writable to reset or preset). Panasonic only.
- **Unit Operation Time** (H:9) — cumulative hours the indoor unit has run (counts only while On). Base register.
- **Under-voltage Count** (H:55) — running counter of supply under-voltage events (0–300), writable to reset. Panasonic only.
- **Human Activity** (H:59, read-only) — ECONAVI PIR presence flag. **Polarity is inverted:** `0` = presence detected (default), `1` = no presence. Users who prefer conventional polarity can wrap this in a virtual inverted sensor. Panasonic only.
- **Operation Current** (H:62, read-only, mA) — instantaneous current drawn by the AC system. Panasonic Etherea 2013 PKE+ only.
- **Power Consumption** (H:61, read-only, W) — instantaneous power of the full AC system (outdoor + indoor combined), not per indoor unit. Panasonic Etherea 2013 PKE+ only.

### Energy history (Panasonic Etherea only)

Panasonic Etherea gateways expose three 32-bit energy counters split across register pairs. The template exposes each half separately:

| Counter | MSW | LSW | Notes |
|---------|-----|-----|-------|
| Today Energy | H:72 (read-only) | H:73 (read-only) | 0–65 535 Wh per half-word |
| Yesterday Energy | H:74 (read-only) | H:75 (read-only) | Rolled over daily |
| Total Energy | H:76 (writable) | H:77 (writable) | Lifetime, writable to reset/preset |

To obtain the full 32-bit Wh value, build a TapHome **virtual device** with the formula `(MSW × 65536) + LSW` for each pair.

Three additional date registers anchor the energy history to a calendar:

- **Today — Year** (H:78), default 2000 — writable
- **Today — Month** (H:79), default 1 — writable
- **Today — Day** (H:80), default 0 — writable

Writing the correct date once is required for the Yesterday/Today rollover to work correctly; the gateway has no real-time clock of its own.

### Additional capabilities

The PA-AC-MBS-1 hardware exposes several registers that the current TapHome template does not yet implement. These are natively supported by the gateway and can be added in a future template update:

- **Window Contact** (H:6, R/W) and **Open Window switch-off timeout** (H:13, R/W) — signal a window-open condition to pause the AC for energy saving.
- **Gateway Disablement** (H:7, R/W, NVM) and **AC Remote Control Disablement** (H:8, R/W, NVM) — administrative locks for the gateway and the physical Panasonic remote controller.
- **AC Unit Alarm Status** (H:10, R) — simple alarm flag complementing the detailed Error Code on H:11.
- **Real Temperature Setpoint** (H:23, R) — the actual setpoint currently applied to the indoor unit; useful for monitoring Virtual Temperature calculations.
- **Auto Mode** (H:37, R) — shows which concrete mode (Heat/Dry/Fan/Cool) Auto has selected.
- **Outdoor Intake Temperature** (H:60, R) and **Input Reference Temperature** (H:65, R) — additional temperature references, useful for diagnostics and COP estimation.
- **Power Consumption — Slow** (H:63, R) — same quantity as H:61 with a slower update rate, more stable for logging.
- **Block Periodic Sendings** (H:97, R/W, FW 2.3+) — disables periodic pushes from the gateway.
- **Modbus diagnostic readbacks** — H:14 (baud-rate mirror), H:15 (slave address), H:21 (max fan speeds supported by the unit).
- **Autochangeover / Limited Setpoint** (H:1150–H:1156, R/W) — full machine-mode block for gateway-side setpoint policies and thresholds.

### Brand coverage

The 32 devices in this template are a **Panasonic superset**. Across other Intesis AC brand variants (Daikin, Mitsubishi Electric, Fujitsu, Hitachi, LG, Samsung) only the base subset is typically implemented — on non-Panasonic hardware the remaining registers read as `0` or `−32768`.

| H:0 | Power | ✓ | — |
| H:1 | Mode | ✓ | — |

| H:72–H:77 | Today/Yesterday/Total Energy (MSW/LSW pairs) | — | ✓ |
| H:78, H:79, H:80 | Today Year/Month/Day | — | ✓ |

> [!NOTE]
> The setpoint range on H:4 is brand-dependent: Panasonic Etherea is 16–30 °C unified, while Daikin DK-AC-MBS-1 is 18–32 °C in cooling and 16–30 °C in heating. The template does not enforce any range limits, so users on non-Panasonic hardware should constrain the setpoint in their automations.

### Supported AC gateways

| Order code | Gateway | AC brand / line |
|------------|---------|-----------------|
| INMBSPAN001I100 | PA-AC-MBS-1 | Panasonic Etherea (**template reference — full register map**) |
| INMBSPAN016O000 | PA-AC-MBS | Panasonic ECOi / PACi VRF (Modbus TCP **native** — no converter needed) |
| INMBSDAI001I000 | DK-AC-MBS-1 | Daikin domestic AC (base registers only) |
| ME-AC-MBS-1 | ME-AC-MBS-1 | Mitsubishi Electric (base registers only) |
| FJ-AC-MBS-1 | FJ-AC-MBS-1 | Fujitsu (base registers only) |
| HI-AC-MBS-1 | HI-AC-MBS-1 | Hitachi (base registers only) |

| SM-AC-MBS-1 | SM-AC-MBS-1 | Samsung (base registers only) |

## Troubleshooting

### No Modbus communication with TapHome

1. Verify the Modbus TCP ↔ RTU converter is reachable — ping the converter's IP and check that its admin UI is open.
2. Confirm the converter is configured for **9600 bps, 8N2** (the PA-AC-MBS-1 default). Match SW3/SW4 settings on any replacement gateway.
3. Check polarity on the EIA-485 terminal: `A+` and `B-` must match on both sides (Intesis ↔ converter).
4. Ensure 120 Ω termination is active on the **last** device on the bus — on the PA-AC-MBS-1 turn SW4-P4 ON if it is the end node.
5. Confirm the **Slave ID** set in TapHome matches SW3 positions P1–P6 on the interface (default 1).

### Temperature readings show values around 200–300 instead of 20–30 °C

The PA-AC-MBS-1 factory default is **decicelsius (×10)**. Either set **SW4-P1 to ON** to switch the gateway to Celsius ×1, or apply a `÷10` divide formula in a TapHome virtual device for each temperature register (H:4, H:5, H:22, H:24, H:25, H:66). A power cycle is required after any DIP change.

### LED blinks 200 ms ON / 200 ms OFF (AC unit communication error)

1. Check the CN-CNT cable between the interface and the indoor unit — the supplied 1.5 m cable must not be modified or shortened.
2. Verify the indoor unit is powered.
3. Confirm the gateway cable is routed away from power/ground conductors.
4. Read register **H:11 Error Code** — `65535` (`−1`) confirms gateway-to-AC communication loss; any other non-zero value is a Panasonic H/F or Daikin letter-code from the unit itself.

### Template values read as 0 or −32768

1. On **non-Panasonic gateways** (Daikin, Mitsubishi Electric, Fujitsu, Hitachi, LG, Samsung) the Panasonic-specific registers (H:38, H:39, H:53–H:59, H:61–H:66, H:72–H:80) are not implemented — they will read as `0` or `−32768`. Use only the base devices on these brands.
2. `−32768` on H:4 Setpoint, H:5 Reference, H:22 External Sensor, H:24 Max, H:25 Min, H:66 Return Path indicates the value has not been initialised yet (gateway just booted or external sensor not in use). This is normal after startup.

### Setpoint cannot be changed from the Panasonic remote controller

When **External Sensor Temperature** (H:22) is set to anything other than `−32768`, the Panasonic remote controller is locked out and the setpoint is governed entirely by the Virtual Temperature mechanism. Write `−32768` to H:22 to release remote-controller control, or accept remote-only operation via TapHome.

### Today/Yesterday/Total Energy register values look wrong

Each counter is split across two 16-bit registers (MSW + LSW). Combine them in a virtual device using `(MSW × 65536) + LSW` before displaying. Also ensure the internal date (H:78 Year, H:79 Month, H:80 Day) has been written once — without a valid date the Today/Yesterday rollover does not track.

### Demand Response commands appear to have no effect on non-Panasonic units

Demand Response (H:58), ECO Mode (H:57), Powerful (H:38), Quiet (H:39) and Human Activity (H:59) are **Panasonic Etherea-specific**. They are not implemented by other Intesis Modbus AC gateways and writes to these registers are silently ignored.

Possible improvements (17)

- H:6 Window Contact — R/W; 0=Closed (default), 1=Open. Signals a window-open condition to pause the AC — useful for energy-saving automations. Not exposed by TapHome XML.
- H:7 Gateway Disablement — R/W, non-volatile; 0=Enabled (default), 1=Disabled. Disables the gateway entirely — rarely needed in production, omitted from template by design.
- H:8 AC Remote Control Disablement — R/W, non-volatile; 0=Enabled (default), 1=Disabled. Locks out the physical Panasonic remote controller.
- H:10 AC Unit Alarm Status — R; 0=No alarm, 1=Alarm active. Simpler alarm flag than the detailed Error Code on H:11 — could complement it.
- H:23 Real Temperature Setpoint — R; actual setpoint currently applied to indoor unit (what the Panasonic remote controller would show). Useful to monitor Virtual Temperature calculations when H:22 is in use.
- H:37 Auto Mode — R; shows which concrete mode the Auto mode has selected (0=Auto, 1=Heat, 2=Dry, 3=Fan, 4=Cool). Minor omission noted in fetch inconsistencies.
- H:60 Outdoor Intake Temperature — R; outdoor coil intake air temperature. Useful complement to Return Path Temperature for COP estimation. Panasonic Etherea-specific.
- H:63 Power Consumption (Slow) — R; same as H:61 Power Consumption but with slower update frequency — more stable for logging/billing.
- H:65 Input Reference Temperature — R; secondary temperature reference (different source than H:5). Useful for diagnostics.
- H:97 Block Periodic Sendings — R/W; 0=Non-blocked (default), 1=Blocked. Stops the gateway from pushing periodic updates. Firmware 2.3+ only.
- H:13 Open Window switch-off timeout — R/W; 0-30 min (default 30). Works with H:6 Window Contact — AC switches off after this delay when window opens.
- H:14 Modbus RTU baud rate — R; mirrors DIP switch SW3/SW4 baud-rate setting. Read-only diagnostic.
- H:15 Modbus Slave address — R; reports current Modbus slave address (1-63) configured via DIP SW3.
- H:21 Max number of fan speeds — R; number of fan-speed steps the indoor unit supports (3 or 5). Useful to adapt UI.
- H:1150 Machine Mode — R/W; 0=Normal (default), 1=Autochangeover, 2=Limited setpoint. Governs thresholds at H:1151-H:1156.
- H:1151-H:1156 Autochangeover / Limited Setpoint thresholds — R/W; 6 registers for cool/heat thresholds and min/max setpoint limits — only active when Machine Mode is Autochangeover or Limited setpoint.
- (none) Combined 32-bit energy values (Today / Yesterday / Total) — Template exposes 3 pairs of MSW/LSW halves (H:72-H:77) as 6 separate 16-bit registers. Users typically want a virtual device that combines them via (MSW\*65536)+LSW to get full 32-bit Wh values (Today Energy, Yesterday Energy, Total Energy).
