page 30 , with the polarity of the pins marked, when the vent valve or fan is set to on.
The 24 V d.c. output on the controller connector is protected from the overload or short
circuit to 0 V d.c. / 24 V d.c. Rtn / chassis. The output supplies the current given in Table:
Controller technical data on page 30 . For higher currents, the output voltage will
decrease and can set to off to limit the current.
