7. ControlsDEVIreg™

The DEVIreg™ 531 is a simple electronic thermostat with a 2-pole switch, using a built-in room sensor to measure and control the desired room temperature. It can be either flush-mounted or surface-mounted.

The thermostat has a dial for adjusting the temperature setting with a scale from to 35.

Furthermore, the thermostat has an LED indicating the current mode (heating, standby or fault).

Benefits: • 2-pole safety breaker

• Low standby consumption

• Sensor failure monitoring

• LED indication for fault

• Frost protection

Standard compliance: • EN/IEC 60730-1 (general) and
