Hi,
I have just moved into a house and the CH system wont work without the HW being switched on. It dosnt matter what position the room thermostat is set at. The controller is a Honeywell ST699 and the boiler is a Baxi Bermuda inset 2 50/4E back boiler.
The controller is set to twice a day CH and HW the boiler fires up no problems every thing gets warm then if I was to put it on manual/constant the CH will not work unless the HW is switched to constant as well.
Thanks in advance.
