Systemate 2000 ignoring Thermostat !
Hi Guys,
I have had the heating on constantly over winter with the thermostat set around 21C. When the recent warm weather hit I reduced the thermostat to 16C. The problem is the Systemate keeps heating the radiators up at random times (often very very hot to touch). I even tried turning the thermostat down to 10C & the Radiators are still on ! The click on the Thermostat was around 24C so !!! Any advice ? I have tried turning the power to the entire system off without success once back on !
Cheers,
AspenJulie23

Check the timer and stat.
If not control board may be faulty

Hi Mike,
The timer is on constant so should be relying on the Thermostat to turn the heating on when the temp falls below set temp ? The thermostat is set to 10C & a thermometer is reading 22C & the heating is still on ! GGrrrrrrr gonna be an expensive one I can tell !

Have you tried turning the timer off?
As it could be the room stat which is faulty.
If you turn the timer off
And the stat.
And it continues to run then it does look like the PCB.
Do you hear the stat clicking?

Hi Mike,
The heating is on constantly even when the timer is set in timer mode ! Turned the timer off as you advised & the heating went off & stayed off finally ! The thermostat doesn't click when the timer is in the off position. However when the timer is in Timer mode or constant mode the Thermostat clicks around 22C. Do you think it's the Control Board ?

Well the thermostat clicks (sound) whether heating is on off or on timer.

Hi Mike, no click from thermostat when timer is turned off (0 position), It does however click when on constant (1 position) or in timer mode (clock position). Strangely in timer mode it clicks wether the timer is active (timed on) or timed off !
Bugging me big time & not to mention costing a fortune !

Mine might be playing up to.
Got in early today, around 14:45 and although the Stat was set to 17 and wasn't on, the radiators were warm, the place felt warm. It's been fine all week since I moved in.
Did your PCB change cure the fault?

Hi PJHB,
yes chancging the PCB board fixed the fault & all is working fine.

New PCB
I have seemingly an identical problems with a systemate 2000.
I have had hot water sensor problems previously which have been easily remedied. Now I have constant call for heat and central heating despite turning the thermostat down and even disconnecting. This seems like PCB to me - do you agree?
I have been looking at PCBs and there seems to be huge variation in price - the cheapest for a reconditioned replacement being £80 up to £300ish for brand new.
Does anyone have experience with the recon parts and can recommend a supplier whose products are reliable?
Thanks

You can try;

http://heatingpartscenter.co.uk/prodtype.asp?CAT_ID=3448&strPageHistory=category
Re-con boards, well that is up to you.
Reliable? Considering it is power surges or lightening strikes in and around the given area / location that takes these boards out most of the time.
Think about fitting something to protect the ACB.
Don't ask me as I have not worked out as to what etc as yet.
