Hi. I have a problem in my new house. It's a 'standard' gas boile
feeding the heating and a DHW tank. There's a 3-way solenoid valve o the exit from boiler to control flow to DHW, CH or both. There was a DHW tank thermostat fitted but missing the cable. The inpu for the thermo, in the controller panel, had been bypassed so that DH is heated to the same temp as CH water, ie too hot for me. The problem is that, when I wired the DHW thermo back in, when i reaches the set temp the hot water cuts off as expected but so does th CH. Is this down to the way the programmer and controller panel have bee installed? The panel has a number of wires around the edge, some o which have been clipped. I assume they are left intact/clipped t select various options during installation. I don't have instruction to decipher though. Thanks
