Electronic thermostat ETL 011


  • Large setting range
  • Small hysteresis
  • Optical operating display (LED)
  • Change-over contact
  • Signal application

Product description

The electronic thermostat registers the surrounding air temperature and can switch a signal current via its internal relay with a potential-free change-over contact.


Signal-processing devices can be controlled directly with the ETL 011. In order to control heating and cooling equipment, filter fans and signal devices the switch module SM 010 or a similar device is needed.


The LED integrated in the adjustment knob shows the closed status of the contact 1-2.


When temperature is rising contact 1-2 opens and the LED turns off. In currentless state (no supply voltage) contact 1-2 opens.
