Hi

Would anyone be able to give some advice - we recently moved in to a rented flat with a Honeywell st6400c programmer controlling the heating/hot water settings. We reset the programmer, and programmed the timings to when we want the hot water to come on (on the 'auto' setting). However it is very erratic and does not come on when set, particularly in the mornings. Any ideas for what the first thing to look at would be?

Thanks
 
Get the landlord to sort it. It's part of what you pay your rent for.

Yes this is true - just checking in case there was a quick solution we could try that we may have missed! Cheers
 
after you finish your settings you must go back to run and close the cover , then select from the bottom bellow hot water and heating position AUTO
