Can someone help!!
My CH consists of a Baxi Bermuda 401 CH unit with back boiler, a Landis & Gyr RWB2.9 programmer and a Grundfos pump. The CH temperature is regulated by controllers on the radiators, I do not have a thermostat. My problem is that even with the CH and HW programmer switched off, the boiler can be heard to 'kick in' and the pump runs resulting in the pipes to the HW tank being very hot.
Any ideas?
