Two ST9400's, both fitted about a year ago, both with same problem - randomly will not run program on timer. Work fine in continuous mode. Wonder if they had a dodgy batch?

Still got the receipts? Check the date and get into your supplier or ask to speak to the rep. The st9400 are not that reliable anymore I've changed tons of them
Honeywell have cost me a lot of money,fitted their stuff for years,it has gone really unreliable,now blown them out,using EPH kit instead
have fitted lots of drayton as well,no issues to date,good kitI have had loads of year old Honeywell programmers with the same problem. All just over a year old.
Like you I always used to be Honeywell mad saying it's the best you can get but I really lost faith with them. I now fit Drayton and have not had a problem and they are really easy to use.
