My Worcester boiler continues to cycle even after the system has switched off at night. Thinking that the switch on the CH Drayton Actuator ZA5 was faulty I replaced the actuator but that didn't work. The boiler must be getting a call to switch on from somewhere and I wonder if the ZA6 actuator on the HW might be faulty. Is this a possibility? My research has shown that the microswitches on these actuators are guilty of malfunction, which is why I replaced the ZA5 in the first place. The only way I can get the boiler to stop cycling is to turn the room stat away down. Or could the Drayton LP722 controller be faulty? Otherwise the system works well and is serviced annually.
I should say this was wrongly posted on the Information Page earlier and I apologize for that.
Great Site by the way.
