Hey everybody
I have zonal heating which gives seperate heating to an annexe and our main house, we have the benefit of the heating going off in 2 seperate directions from the boiler. So we had a V4043H motorised valave installed on the pipe going to our house and 1 on the pipe going to the annexe. We also have a Honeywell ST9400C programmer installed with 2 receivers and a DT92E thermostat in both the main house and the annexe.
Now the problem we are having is when the annexe calls for heat BOTH valves open which then heats both the annexe and main house, even when the programmer is set to off for the main house, plus the receiver for the main house does not light up green. If the main house calls for heat the valave for the annexe stays closed. We first thought it could be a faulty valave but we replaced it and the problem still persists.
I'm wondering if it could either be a wiring issue or an RF issue?
Has anyone come across this before?? Help needed as I think it has stumped my plumber!!!
