Hi, just returned from holiday and the boiler /CH is not working. My brother looked after the house an assures me that everyday the HW and CH came on when the timer kicked in and the just stopped working yesterday. I have the water and CH set to constant at the moment and the boiler is not even firing and no pumps etc are working. I have a standard boiler with hot water tank.
The room stat was changed a few weeks ago to a Honeywell DT90 and has been working for 2 weeks fine.
Any ideas?
