My pumps running constantly causing my boiler to fire up every 30mins,
First of all checked my 2 port actuators there fine and in the off position, secondly checked the fuses on the pcb and visually checked resistors and they all seem fine? Noticed that n1 light was on on pcb. Any ideas? Thanks!
They both power open when when call for with heating or hot water, then when I turn off the demand they both shut. Programmer is new today and fault still occurs
Hi, I'm having problems with my heating / hotwater??
I have an s plan system. When I programme my hot water to come on my radiators get hot as well! So I whipped off both 2 port actuators and they both seem to power open when I ask for hot water or heating?? Thinking this was a programmer fault...
