Hi, I have a honeywell ST 9400c programmer. I have to reset the time every time there is power disruption
I think it is the inturnal battery gone flat.
Will the programmer run OK with out this battery?

The price of these honeywell valves are now a silly price and not worth it.
So if I buy a cheap brand and it only last 2-3 years I am quids in.
Hi Thanks for your reply. I would keep it as a Y plan as I Can change the whole unit in about 20 mins.
I just don't like waisting money on parts that are not up to the job.
