Hi, Got a call out to what was described as a programmer problem. Burner operates correctly as does the DHW. When system is operating in heating mode, burner fires correctly and pump runs......radiators get hot. When the boiler thermostat is satisfied, burner stops and so does the pump........radiators then cool down as pump not running. Boiler cools. thermostat then kicks in, burner fires, pump comes on, radiators get hot and so on.
Any clues as to the fault? Spoke to Worcester Bosch technical for quite sometime without a definitive answer except it could be the board. Unfortunately the wiring diagram on the Worcester Bosch site is incomplete.
Any sensible suggestions?
Thanks,
Nick
