REGULUS - TRS 4 Controller - www.regulus.eu
D - ELECTRIC WIRING
Sensor side - max 12V
Mains side - 230V 50Hz
Note: If the RC21 remote controller or another room thermostat is connected, the bridge at S6 has to be
removed.
Note: If the hydraulic variant 4, 5 or 6 (page 5) is used, then the sensor of heating circuit 2 shall be connected
to terminal S3.
If an accumulation tank is used, the sensor can be connected to terminal S4 (see menu 7.4).
- Temperature sensors S1 – S6
