Test Method
Voltage and Position
Control in Central Heating
While the device is connected to the power, the motorised
valve cable is removed and the device is put into central
heating mode. Resistance between terminals no. 1-2 is
measured. The value must be between 210-240 VAC. The
pin must be in the down position when the power is off and
the domestic water is turned on by installing a motorised
valve.
