VerifiedHi my name is XXXXX XXXXX lets see if we can get you sorted in the shortest possible time. The display PCB only runs the digital display and temperature controls. The main PCB runs the boiler
Customer replied 10 years ago
That sounds possible. I didn't even know I possessed a hot water preheat! I take it it costs to run it, or is it more economical to keep this on. Also could you tell me where the control for this is as I have no idea. I just want to keep my costs down as much as possible as I live in an old drafty house which is eating my money at the moment.
On your model the preheat is turned off by turning the hot water temperature control to about 9 o'clock
