Hi,
I have a a problem with my Vaillant combi boiler with wireless controller.
The problem is that the heating is always on when there is power to the boiler, no matter what the setting on the controller. The only way to stop it is to turn off the power at the mains. It sounds like the pump is always running, and the gas fires up frequently. The thermostat on the controller is set to 15 degrees, there is no hot water demand and the controller says says 'off', but the boiler keeps running.
There is also a switch on the boiler which looks like it switches between hot water only, and both hot water and heating. Even with this on the hot water only setting, the heating stays on.
Any idea what the problem could be?
Thanks,
Dan
