Electronic thermostat
ETR 011
Electronic thermostat for controlling heating, cooling devices, filter fans or signal transmitters. Detects the ambient temperature and switches via the output relays with changeover contact. If, for example, a heating system is in operation, the integrated LED lights up.
- Large setting range
- Small hysteresis enables precise control
- Visual status display (LED)
- Changeover contact (heating or cooling)
- Clip mounting
