What it is

The EPH Controls CM3 is a mains voltage room thermostat used to switch a heating circuit in response to room temperature. It operates on a 230 V ac supply and carries a 10 (3) A switch rating as stated in the product name. It is supplied as a standalone control unit for wiring into a heating system.

Before you order

  • Confirm the existing thermostat is a 230 V ac mains unit, not a low voltage or battery-powered type.
  • Check the switch rating of the circuit against the 10 (3) A figure shown in the product name, particularly where a pump or boiler is switched directly.
  • Note the number of wires at the existing thermostat position and whether a neutral is present, as mains thermostats require a neutral conductor.
  • Verify the product code CM3 matches the unit being replaced.
