Like our E816 standard Set-Back Thermostat, the E818/24Vregulates room temperatures to two different temperatures, a low temperature ‘Set-Back’ and a higher boost temperature ‘Setpoint’.

Instead of a pushbutton which is used to toggle between the two temperature levels, the E818/24V utilises a Remote Control Input which selects between the high and low temperature levels through the user making and breaking the two remote control contacts.

Typical interfaces to the Remote Control Input may be through a time clock, PIR motion detector, BMS relay output, mechanical toggle switch, magnetic door contact etc. This unique feature can eliminate the user interface for switching between the high and low modes, so providing an effective solution to the automation of heating areas that are infrequently occupied.

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.
