my central heating works but only if before it comes on, i go upstairs to the zone valve, and set it to manual. This is the only valve i can find ( new house) and is only 2 port (1 input 1 output).
Every time the heating goes off and the timer comes back on, no heat in radiators, I check the valve and its gone back on its own to auto!
Any help or is the valve broke?
