The set-back feature of the E816/24V incorporates two different temperature setpoint levels within one thermostat offering a cost effective and efficient solution to heating or air conditioning areas that are only occasionally occupied, or scenarios where a boost feature is required.

The E816/24V thermostat regulates to one of two temperature levels which the user is able to select between by pushing the button on the side of the unit. LED indicators illuminate to clearly identify which mode the unit is in.

Full adjustment of the two temperature levels can be achieved only through adjusting internal thumbwheels located inside the tamperproof unit, so preventing unauthorised modification to the thermostat’s configuration.

24 Volt (/24V)
This thermostat is designed to operate from a 24 volt (AC or DC) power source (instead of the standard operating voltage of 230V AC). This is primarily used for low-voltage systems such as under-floor heating.
