I was wondering if anyone could give me direction on a fault with my boiler setup.
System is as follows:
Boiler Gloworm 50FF Micron (Spit) with Programmer built in
Indirect Hot Water Tank
x 1 Pump.
x 2 Honeywell (silver top) 2 port zone valves.
Digital room stat ( wired to boiler, battery powered)
Cyclinder Stat (Drayton replaced 7 months ago)
So I though I would fire up the CH this evening to check it works after being off for the summer and nothing happens, no boiler firing no pump firing, on closer insepction the CH zone valve does come on (can feel the hum and the manual lever slides across).
I have basic knowlegde of the components and what they all do so I started testing the boiler in different situations and this is what I found:
CH set to ON with room stat calling ( room stat clicks when set higher than room temp which suggests it is working as normal)
* Boiler doesnt fire
* Pump doesnt start up
* Zone valve comes on
HW set to on, cyclinder stat calling
*Boiler fires up
*Pump Starts
* HW zone valve only comes on
* System appears to work as expected as it has done all summer
HW zone operational and heating, then turning CH to on and calling for heat.
* Boiler stays on
*Pump Stays on
* HW & CH zone valve are open
* Rads warm as normal
HW zone turned off at programmer whilst both HW and CH zones are active (heres where it gets interesting)
* Boiler stays on (heating)
*Pump stays on
* HW & CH zone valves are open
* Rads and HW continue to be heated
I am inclined to check the CH zone out as the possible fault, but from the information above can anyone suggest anymore tests or what they think is wrong?
