Hi, tried this question on plumbing and no success yet, suppose I should have been on this forum. Have a problem with my mid pos valve. When I call for HW, CH, or both, all works as it should. But from the mid position when I call for CH only, the valve stays where it is, heating water when not...

I was installing a heating system where I was running the hot water circuit as the last T. He asked me why I was doing it and then said that that was only applicable if it is thermo syhoning and on a 3 port valve. I told him it had nothing to do with thermo syphonng but the pump pushing it. Does...

any one know if a honeywell 3 port head fits on a landis & gyr valve body?

thanks
Need to replace on of these and as they are no longer available is their a wiring combination to make a modern 2 port valve work on this system? Any advice most welcome
At a job replacing a cylinder and he mentions the boiler kept running even though the programmer wasnt calling. Apparently some history of the CH 2PV sticking on. I found it under some floorboards....nice. So even with the actuator closed, the switch is ON and therefore running the boiler (there...
Morning guys,
fitted two of the above yesterday without fuss until I refitted the actuators, then noticed that one of the manual override switch doesn't fully return to auto position when released from manual, works perfectly fine when not fitted to the valve body. Swapped them around and tried...
Evening guys hope your well ... Does anyone know if there is an issue installing the above on vertical pipework? Instructions only mention horizontal installation which has thrown me a bit, would not have thought there would be an issue but thought I'd check with you guys.

Anyone got any suggestions why a new honeywell 3 port valve won't settle mid position without constantly moving between micro switches internally, causing a constant clicking every couple of seconds? Hot water only ok, heating only ok. All other external controls giving 230v when required (...
Ok so the 3 pot valve must be naffed. Stays in mid position when calling for hot water. But boiler won't fire when calling for just heating. I don't get 240v in wiring centre on stat. But if I put motorised valve in manual I get 240v
Hi guys. To all those who have already fitted a three port mid valve ..
I've just popped over to sort out a hot water problem for a friend and discovered a sealed system with honeywell components and three port mid valve.
