Hi, can anyone please help. I bought the house recently with installed Baxi Bermuda B boiler with Randall 102 programmer. The problem is that I could not get Hot water only. When switched to Water and Heating - everything works fine, when switched to Water only, the pump stops running but the radiators upstairs still running. There is obviously something wrong with the wiring from the 102 to the boiler or may be I need to stop a tap somewhere.
