# Air conditioning

Last updated: 2026-11-04

TapHome system can be used to control air conditioning split units or outdoor units.

## Data connection

**Advantages:**
- Simple configuration
- Minimum or zero additional costs
- Full feature set

**Disadvantages:**
- None

### LG Air Conditioning via PI-485 and LGAP protocol

Communication via RS485 (Bus) connection.

Multiple split units can be fully operated from TapHome with minimal additional cost. The PI-485 is supplied directly by the LG supplier.

### Toshiba

For integration with the TapHome system, a Modbus gateway called TCB-IFMB640TLE is required.

## IntesisBox communication hardware

**Advantages:**
- Wide compatibility list (supports Daikin, Fujitsu, Hitachi, Hisense, Midea, Mitsubishi Electric, LG, Panasonic Etherea / VRF, Samsung, Toshiba, etc.)

**Disadvantages:**
- High price

## Vaillant

For the Vaillant aroTHERM plus heat pump with the sensoCOMFORT VRC 720 controller there is a [community template](https://taphome.com/en/compatibility/vaillant-ebus-micro-ebusd-http/), not yet verified on a real installation, that works through the eBUS Adapter Shield or Stick C6 with micro-ebusd and its HTTP API. TapHome has no integration for the myVAILLANT cloud. Vaillant units communicate over eBUS: an eBUS adapter running ebusd, for example the [eBUS Adapter Shield C6 Stick](https://taphome.com/en/compatibility/ebus-adapter-shield-c6-stick/), publishes the values to the [TapHome MQTT broker](https://taphome.com/en/docs/integration/packet-parser/mqtt-broker/), where you read them with your own [Packet Parser](https://taphome.com/en/docs/integration/packet-parser/) scripts. Without a data connection, a TapHome relay output can switch the unit's heat demand or SG Ready input, if the unit has one (see its installation manual), as described in [Hydronic heating and cooling](https://taphome.com/en/docs/setup/requirements/#water-heating).
