Electronic Thermostat
ETR 011

  • Large setting range
  • Small hysteresis
  • Status indicator (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 is closed. (e.g. when a connected heater is operating).
