The WTC-3 will stop the system pump when there are no
r
equests from room thermostats. In this case, all actuators
a
re closed down and the pump will stop.
Output eight on the unit switches on if the output of at
l
east one control circuit switches on. The output may be
u
sed for the activation of the pump.

If analogue thermostats are connected to the base unit
then the out of use thermostat inputs must be connected
in parallel with the heating/cooling changeover input,
otherwise output eight will remain continuously switched
on in the cooling mode. This will keep the pump activated
during the cooling period.
