The pump and boiler both switch off
The actuator stays in the Ch position and gets hot until I carry out a reset it then returns to HW position and cools down
Will being constantly powered damage the acctuator ?
The whole head was replaced
Seemed to get stuck in CH position
This system is linked with hot water solar panels may be I should call the supplier who installed the whole system 4 years ago. ?
Any idea about the back light not working ?
Thanks Andrew I think you have gone as far as you canon this one.
Will do !
