Installation Diagram
The controller can be mounted on a DIN rail (A) or a wall (B). The installation involves connecting power, actuators, and optional components like the TRF03 transformer and RF antenna.
Step 1: Mounting and Wiring
- Mount the controller unit.
- Connect the power supply (24V or 230V).
- Wire the actuators to the designated terminals. Ensure correct polarity for NC/NO connections.
- Connect the optional TRF03 transformer if using 24V actuators.
- Install the RF antenna if wireless communication is required.
Step 2: System Configuration
- The system supports a MASTER/SLAVE configuration for multiple controllers.
- Wireless thermostats (BT-A03 RF, BT-D03 RF, BT-DP03 RF, BT-CT02 RF) and other Watts devices (BT-CT03 RF, WFC-03 HCM RF 230) can be paired with the controller.
