Room temperature controller 230 V with LED
Referenznummer: 51201000
The Basic B room thermostat enables simple measurement and control of the individual room temperature in a room. It is suitable for connecting up to 10 electrothermal actuators for water-led heating systems. This low-cost variant has basic functions.
If 230 V is applied to input C, the cooling mode is active. If 230 V is switched off, the device automatically switches to heating mode.
After each switchover, the LED lights up for 10 seconds in the colour of the current operating mode.
Setting the control mode and valve type
- Pulse width modulated control (PWM)
- Valve type normally closed (NC)
This setting can be used with most heating systems without adaptation.
Setting the temperature limits
The room thermostat has a setting range of 5 ... 30 °C. The adjustment rings on the central plate can be used to limit the temperature setting range.
The specified temperature values may deviate from the actual room temperature depending on the installation location.
