Hello,
This morning when I woke up and came downstairs, I noticed my main floor had not received heat for quite a while. When I went up to bed, it seemed to be working fine.
Upstairs, the heat is working perfectly. Downstairs, it seems to be doing nothing. Interestingly, last year around this time, the problem was reversed. Last year, upstairs was not working and downstairs was working.
The boiler I have is a Crane Sunnyday 102. Are there any knobs or switches I can manipulate to attempt to return functionality? I have recently bled the radiator upstairs.
I have not been able to find any information on this boiler at all. Any suggestions greatly appreciated.
Thank you in advance,
Aaron
