Electrical heating system Query

[SparkyChick]

I've been trying to find information about that timer module. If it's stuck in programming mode that may be the only issue.

I'm not overly keen on suggesting random pressing of buttons, but does the module do anything when you press the PROG button?

Are there any makers marks on it, I tried zooming in on the photo but couldn't see any. Any chance of a close up of the timer?

No markings anywhere to be found :/ and no reset button... I can not, for the love of me, figure out a reset combination of buttons. Nothing happens when I press or hold the program button. When I press the right button on the lower row it changes the digits - goes as far as 45 and then comes back to 01 but nothing else. And while doing this nothing else seems to happen when I press any of the buttons.

I would turn off the main switch and then back on ............ after a few seconds

 

[Albena_Ivanova]

That was the first thing I tried and it didn’t work. still stuck in this mode

Leave it switched off for longer?

So it's a Crabtree 302/TD1 I believe. Got a query in with Crabtree technical to see if I can get hold of the instruction manual.

I don't think turning the power off will help as from what I've gleaned so far, I believe it has an internal backup mechanism that should maintain the clock etc. for 150 hours.

FYI the control module looks to be just a standard DIN mounted programmable time switch. I would have thought this would switch in the contactor to the left of it which is basically the switch for the heaters. It probably isn't manufactured by the same company as the heaters but could be worth a try. It also isn't anything to do with the consumer unit in which it is installed.

If you can't get that one to work it shouldnt be a major job to replace.

From the looks of it the 302/TD1 is still a current model, and with the 18th just around the corner, would probably be a good idea to stick with Crabtree parts.

Oh that would be amazing! Thank you also for giving me some more information about the timer itself!
