hello, id like to know how to rectify a problem with my MV. My timer appears to be functioning ok as it switches on the HW as programmed, However for CH the boiler is not firing up. Originally i though thus maybe a faulty room stat, however after replacing it the problem remains.
So I set the timer to CH on, and then pulled the lever on the MV over to CH and the boiler fired up, however if i let go of the lever it pulled itself back. Do I have a faulty MY, or is it not getting the info it needs to switch over?
