Hi again and apologies for posting new thread just after closing the last one, but need a little more advice.
You may recall I fitted a Honeywell 927 Wireless Programmer to this system and after various teathing probs all settled down nicely.
Previously I controlled room temps via the control on the boiler, set at quarter when not too cold, up to 3 quarters if weather turned cooler. Now of course I have the programmer set with various times and temps and just leave the boiler stat on full.
Now of course the boiler temp is higher than before and it seems to have introduced a pressure problem. I have no noticable leaks and no overflow via PRV, but in the morning, pressure has dropped to below operating point. I top up via loop for only seconds until middle light comes on and boiler fires. But after running for some time the 'high pressure' light comes on. No probs, boiler runs of course, but next morning back to low pressure light again.
I have measured the pressure at the EV and it is only half a bar. Is this simply my problem, a case of just 'pumping up' to a bar?
I know the system has to be de-pressurised when re-charging the EV, so was planning to close flow/return valves and opening drain on boiler to release pressure?
Any views welcome (again....)
