E810/M2S Two-Stage Robust Thermostat with remotely activated set-back

Product Code: E810/M2S

The E810/M2S is a 2-stage thermostat with a remotely controlled set-back functionality, offering a high quality and robust solution to tamperproof energy-saving thermostatic control. It utilises a high-accuracy radiant heat sensor in conjunction with its die-cast aluminium case and tamperproof screws to ensure vandal-resistant yet accurate tamperproof energy control.

The E810/M2S regulates to a fully adjustable temperature Setpoint between +12°C and +26°C, combined with an adjustable temperature hysteresis (differential) of anything between 0.25°C and 4°C. Additionally an adjustable Set-Back (°C back from the Setpoint) of up to 14°C can be applied. A PIR motion sensor or timeclock is typically used to activate the remote input which selects between the Setpoint or Set-Back temperatures (‘High’ when the switch is closed and ‘Low’ when  the switch is open).  This ensures the room temperature is regulated to a comfortable level when it is occupied yet significantly reduces heating energy consumption when the room is empty.

2-stage functionality is used to select between two different fan speeds when the E810/M2S controls the heating device (often a multi-speed fan convector).  The High fan speed is activated upon the thermostat detecting the remote switch being closed, such as when the room first becomes occupied.  This allows the room temperature to boost up to the target level quickly using the High fan speed.  Once the target temperature is reached the fan is turned Off and the Low fan speed is selected thereafter to keep the room temperature constant.  See Figure 1 in the Product Guide for a graphical representation.

This 2-stage functionality ensures the room temperature quickly raises when it becomes occupied or a specific time of day is reached, and will then switch to a much quieter mode of operation once the room temperature is up to the desired level, or the room becomes unoccupied.  This functionality makes the 2-stage thermostat ideally suited to areas such as classrooms where a quick initial response is required, but quiet operation is required thereafter.
