The control unit sends and receives BUS signals to and from the thermostats and sensors to actuate actuators and other heating / cooling equipment / generators.
ECO settings are possible when connecting the I-143 programmer to the entire installation or by connecting the Smatrix Base programmable thermostats to each room.
There are two possibilities to connect thermostats or accessories to control units:
- BUS series topology (from thermostats to thermostats)
- star topology (each thermostat will be directly plugged in with Star Mode)
It includes:
- Smatrix Base 6 channel control unit
- Transformer
- Quick installation manual
- Mounting materials
functions:
- Robust RS485 bus communication
- Electronic control
- Two-way communication with up to 6 thermostats
- Connection of max. 8 24 volt actuators
