Last week my central heating went off when it was set to be on, I
managed to restart it by powering off/on the controller/boiler.
Since last night the central heating only works when the hot water
program is active. As soon as the HW program goes off then the
central heating doesn't work, no boiler activity, pump is off.
The controller is a Siemens RWB29 but I tried the old LandisGYR
controller but the problem is still there.
The boiler is a Glowworm Ultimate, any ideas what the problem might be?
