Hi Guys,
Appears this timer/programmer maybe thinks its the wrong time since it was on at 1.00am this morning when it should have been off at 9.30pm.

Looked at it today and it is set to 'timed', but when I finished checking and making sure the the clock, date, year and CH & HW times were correct, and was within the time when it should fire it doesnt.

Press Advance and it fires.

Its not RF just a wired stat.

Any ideas?

Does it work with on ?

Oh Yes - no problem getting it to work - just that the timer says it should be On - but it isnt,
So have to press Advance to get it On.

 

[ShaunCorbs]

sounds like the timers at fault

Thanks ShaunCorbs.
Was all ready last night to order a new timer - This morning its working fine again!
Maybe the electrical safety check on the installation at the house on Thursday had upset the timer electronics with the repeated on/off.
Appreciate your input and fingers crossed.
