Howdy,
I have never had any problems with the old dial type stat but have changed it this winter for a wired programmable type.
Since then, on occassion the boiler has gone to lockout and i have had to reset. Anyway, i watched it the other day and the following seems to be happening which is causing the lockout;-
-not when boiler is firing but just as boiler is about to fire ie proving ignition, checking for flow etc etc if at this time the room stat temp is reached and therefore clicks off, i hear the motorised valves closing,
- then going to check boiler i find it is flashing red as for lockout, its as if it is sensing this closing of valves ie no flow, as a problem, a quick press of reset and it stays orange ie temp satisfied.
If the room stat clicks off when boiler is firing, the boiler simply stops, valves close and boiler flashes orange ie temp satisfied straight away, and left in standby mode ready to go again.
Anyone any ideas, is my room stat useless (sunvic)??
Should the room stat know what boiler is doing, therefore let it finish it's cycle or run on for a bit??
Help please.
