E825 Tamperproof Thermostat

Product Code: E825

The E825 tamperproof room thermostat offers an accurate, high quality contemporary solution to temperature control.  The tamperproof nature of our design prevents casual adjustment of the temperature by room users.  The E825 tamperproof thermostat is a perfect solution for controlling the room temperature in public areas or commercial and industrial situations where temperature adjustment is not required or needs to be disabled.

Utilising a high accuracy temperature sensor the E825 regulates heating or air conditioning within a selectable temperature range between +12°C and +26°C in conjunction with an adjustable hysteresis (differential) of anything between 0.25°C and 4°C.

The E825 is supplied as a wall mounted unit that is designed to fit into a British Standard electrical back box.

Thermostat Variants:
24 Volt (/24V)

Powered by 24 volt (AC or DC) supply.
