Initially boiler working fine, central heating stopped working but restarted when we opened 3 way valve manually by lever on side, now boiler will not even ignite ? needed new 3 way valve?
Hello,
I believe the 3 way valve of my heating system is broken, the old valve is model Landis & Gyr MAV-322, is this able to be replaced with model Honeywell VC4613-30.
If so can someone tell me the correct wiring as I am unable to find a diagram. :roll:
I would appreciate any advice you...
