Electrical heating system Query

[Albena_Ivanova]

Hello!!

I am writing here to ask if anyone can help me with an issue I am facing. In the apartment I live in, I have Applimo electric radiators mounted into the walls and a radiator in the bathroom. There is also a Sunvic thermostat (old one, not digital) mounted onto the wall in the living room. They all seem to be connected to a small program panel installed where the circuit switches are. It appears that by looking at the screen of this control panel it is somehow stuck in programming mode and I can not get the heating running. I do not have any manual and am struggling to find such.

Do keep in mind that the fuses in the panels next to the radiators have all been replaced with new working ones, so this was obviously not the issue.

Does anyone have any advice or tips on how to get the system running?

Any help is much appreciated!

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!

Is the contactor to the left switched by the programmer? If so it could have failed

Crabtree have got back to me. Here are the instructions for the timer.

Ah, Reset;
Day + Month + Clock + Hand (all 4 corners)

Obvious, Not..
