Changed Controller now no heat in downstairs rad?

peeeet · 14 Nov 2004

I have just changed the controller on my CH system.. nothing flash just a simple analogue one... I only have 3 rads on the system but now only the upstairs RADs work, the one downstairs is cold. What could I have done wrong.. ie could I have got the HW & CH wire crossed ??

Well, I did think that but have not checked it yet.. The rad was hot'ish before I changed the controller...

It seems like coincidence, it's very unlikely for the controller to affect the direction water flows in a system unless you have upstairs and downstairs heating zones. Tell us more about your system.
