Electronic Thermostat
ETR 011

  • Large setting range
  • Compact design
  • Small hysteresis
  • Optical function display (LED)
  • DIN rail mountable

The ETR 011 electronic thermostat is used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat senses the surrounding air temperature and can switch both resistive and inductive loads via an SPDT contact. The integrated LED is lit when the NC is closed (i.e. connected heater is operating).
