If got quite a complicated control system on my heating system:
2 heating circuits and 1 HW circuit ( each opened/shut with 2 port valve )
1 heating circuit has it's own Room stat and timer. ( this one has the problem)
the other timer controlls the other heating and HW citcuit ( this one works fine)
So on the problem circuit:
timer on, room stat calls for heat = no operation of valve, no firing of boiler, no heating.
Is there an easy way to tell if it is the 2 port valve or the timer?
If the timer is ok and it is just the valve, should manually opening the valve, complete the circuit from the timer and so power pump/fire the boiler? cos it doesn't.
