Hi to all,
re: viessmann vitola 100 with vitotrol 150 controller.
is anyone out there familiar with this boiler control?
i have an ongoing problem in that the central heating pumps almost constantly in the winter regardless if whether the CH water is being heated or not. there is a frost protection function which can cause this if the outside temp is lower than the code set on the controller but the pump has been going even when the temp is +12 degrees, also i have tried de-activating this function and still the problem persists.
i have contacted viessmann for ideas but they have not been forthcoming with answers....
anyone know of a coding address that would be likely to need adjusting?
thank in advance for any help,
