Hi all

My heating has packed up tonight and it looks like it's the SCR receiver that's at fault. There are no lights showing on it and am getting no repsonse when I change the temp on the wireless thermostat. I've taken the SCR off of it's wall mount and confirmed that there is 240v across the N and L

Am I safe to assume that it is the unit that is at fault ie if there is power there should the red led light up when the unit is mounted or do I need to test the other 3 terminals as well (if so how)

Any ideas what the fault could be, I've seen plenty of posts about having a green light with no action because of a faulty capacitor but nothing where the units doesn't light up at all

Lastly if I do need a nw receiver where is the cheapest place to get them or is there a non branded equivalent I could use

Many Thanks

Jim

Have you tried power cycling?
Have you checked the battery in remote stat?
Have you tried re-pairing the two?
Have you tried moveing the remote stat closer to the receiver?

I've already tried killing the power to the receiver and removed the batteries in the stat (a RF3 by the way)

But problem is that the receiver will not power up so can't re-pair the 2

Cheers

Sorry, I cannot really help beyond that, I have no experience of the
unit.

In true DIY tradition, open it up and investigate the internals.
Start with the power supply as most likely culprit.

Hi Jim

Did you resolve the problem you had with the Digistat SCR?
I have no lights, but power is present at rear of SCR unit

Same issue as you I think.

Did you work out how to fix it?

Turn the boiler off at the switch and then while holding down both buttons
on the receiver switch the boiler back on.

I had this problem and it was the capacitor mentioned in many posts and on YouTube. Replacement caps are available on eBay and easy to fit if you can solder. Search eBay for digistat capacitor, they are around £4, or around £15 if you want them fitted for you.

Dear Mr Jim

If your boiler's Digisat SCR wireless receiver is not receiving signal it
means there is miscomunicatin between thermostat and receiver they both do not
communicate.

Best thing to do

First switch off boiler from main socket and wait for 5 minutes

And then turn on the socket then this will resolve your issue.

Many thanks

that has worked even with my old wr1 and a boiler. I have switched of the fuse
of the boiler off for 5 minutes. Then turn it on and run quickly to press the
top 2 buttons for 15 seconds. My heating worked shortly after! THANKS!!
