Star wiring topology
- 12DO DIN Module is installed in electric box
- Power cables are laid separately for each heating circle, each blinds motor or each light.
- 24UI DIN Module is installed in electric box
- Data cables are laid separately for temperature sensors in each room, or to lights and blinds switches in each room. These inputs are in the electric box connected to the 24UI DIN Module.
- For installation of temperature sensors in the star topology, you may need to calibrate sensors. You would need a standalone reference thermometer. Here is a recommended one. Calibration is set in Advanced settings of the temperature sensor.
Daisy-chain wiring topology
- 2 DI-DO-NTC Bus Module is installed in junction box for lights or blinds switches
- From electric box is laid just one 3×1.5mm2 power cable. Then from the switch junction box one extra power cable goes into blinds motor or light. That extra power cable is being switched by the relay in the 2 DI-DO-NTC Bus Module.
- One data cable is laid from Core in electric box and it is wired along all junction boxes. Light and blinds switches are connected to inputs in 2 DI-DO-NTC Bus Module. Also temperature are sensors are connected directly to 2 DI-DO-NTC Bus Module.
- Below is an example for connection of temperature sensors in a daisy-chain topology:
- Insert 2 NTC Bus Module into light switch junction box in every room.
- Connect data cable to bus connector in Core.
- Lay the data cable from switch box to the first room, then to the second room etc.
- Attach room temperature sensor to light switch mounting frame.
- Insert sealed floor temperature sensor into cable pipe.
- In the last module on the bus, connect A and B with 100R resistor to terminate the bus properly. You can find this resistor in box of Core.
Hybrid topologies between both star and daisy-chain topology are often practical.
- Outputs for heating control in the star topology
- Temperature sensors inputs in the daisy-chain topology
