Firstly Hi All,
We have recently moved into our new house and every house we move into we seem to be jinxed with duff heating!
Let me set out our system:
We have a baxi boiler in the kitchen, just a standard boiler not combi.
Then in the airing cupboard we have what looks after some research to be a honeywell s system. Two v4034h zone valves control flow to the CH and HW. The system is controlled by a Potterton EP2000 programmer and has a junction box which links the programmer with the two zone valves.
The system appears to be wired in incorrectly but I cannot locate a wiring diagram any where. The problem is that the HW cylinder stat controls everything... ie when the HW reaches temp, the boiler and pump switch off even though the CH hasnt reached temperature.
Firstly can anyone lay there hands on a wiring diagram or diagnose the problem. I can include a list of what is connected to what etc. if it helps.
Thanks for your help everybody...
Ian
