Hi,
Had a few problems with our Potterton Suprima 50 boiler that has resulted in a few visits from the Heateam chaps. To cut a long story to the short current problem, the engineer replaced a thermistor yesterday and said all should now be well. However, since he left, it’s transpired that, in fact, the CH runs all the while – even if it’s just HW set on the timer.
We’ve booked a return visit but earliest appointment is Tuesday. In the meantime, I’ve had a look in the boiler cupboard – where the engineer had a brief poke yesterday – and found that the Honeywell Sundial Y Plan diverter is set to Manual. My guess is that this may be the problem – should the diverter valve be set to Auto?
I’ve had a look at Honeywell’s documentation for this product but, so far, I’ve drawn a blank. So any help/advice appreciated.
Harry.
