The E814/F accurately controls heating or air conditioning within a selectable temperature range between -2°C and +12°C in conjunction with an adjustable hysteresis (differential) of anything between 0.25°C and 5°C.

The thermostat offers greater flexibility and control with a semi-automatic on/off push button. In the ‘on’ state the temperature level will be regulated at the set point until the room user disables the thermostat by pressing the push button to select the ‘off’ state.

LED indicators illuminate to signal which state the thermostat is operating in. After a selectable number of hours in the ‘off’ state (any time between 1 and 15 hours is selectable), the thermostat will automatically revert back to the ‘on’ state ensuring that the room will be at a comfortable level the next morning.

Frost (/F)
This thermostat offers a much lower thermostatic control range of -2°C to +12°C. The unit operates as normal but has a lower temperature setpoint, primarily used for frost protection.
