Typical Fan Convector Wiring Examples
The diagrams in Figures 3 to 5 illustrate a few generic methods of how to electrically connect the
thermostat to a multi-speed fan convector. If you are unsure which of the below diagrams is most
suited to your application, please contact our Technical Support team with the specifi c make an
model of heater for further assistance.
Note
: The heater may have more than 2 speeds, however the E810/M2S can only control a
maximum of 2 speeds (plus ‘Off’). When selecting the low fan speed, ensure that in the worst
case there is still suffi cient heat output to maintain the desired room temperature. A medium
speed may need to be selected for the low speed in some cases.
Figure 3
: Hot water fan convector (a)
The transformer and the fan are in the
same module.
The thermostat routes the Live supply
to the correct speed selection terminal
on the heater.
Figure 4
: Hot water fan convector (b)
The transformer and the fan are in
separate modules.
The transformer has different speed
outputs. The thermostat routes the
correct speed directly to the fan.

Rather than changing fan speeds
