Electronic Thermostat ETR 011 Series
- Large setting range
- Small hysteresis
- Optical operating display (LED)
- Change-over contact
- Clip fixing
The electronic thermostat is used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat registers the surrounding air and can switch both inductive and resistive loads via relay with change-over contact. The LED integrated in the adjustment knob is lit when the NC contact is closed (e.g. when a connected heater is operating).
