Salus RT500rf Thermostat - LED display shows room temperature too high (but isn't!)

[tomb86]

Hi there

I wonder if you can please help. I have a Salus RT500RF digital thermostat been working fine for years until just now. The digital display is showing the room temperature as HI°c meaning the room temperature is over 45° - it's very much not and now the heating won't come on - any idea as to how to override this?

Many thanks
Tom

Pull batteries out, wait for 5 mins and then battries back in n try again.

Thanks Londoner2 - we have already done that we've had the batteries left out for about 30 minutes. We've also tried resetting it too.

Have you read the the manul:

Yes - we have the hard copy manual also. There's no help on there on how to troubleshoot this issue.

Here's a screenshot from the digital display

I think I've seen a recent post with a similar issue - the solution was to get a new thermostat.
Unfortunately Salus don't have a very good reputation around here!

If you need heating now, show us a picture of your receiver, and we may be able to bypass it.

Hi there thank you - I feared that'd be the case! This is the receiver .

Doesn’t look like there’s an override. Is there a reset under the flap on the thermostat?

Had problems before with these but never HI.

Things to try...
New batteries (not rechargeable)
Move the unit nearer the receiver
Change the pin config
Reset everything

As @CBW , there's no override on the front of the receiver.
If you feel comfortable taking the cover off, you could show us the wiring behind.
However, this may not be something you want to do, this time on new year's eve!

The rear of the receiver should look something like this...

With the power isolated, put the wires from NO and COM into the same terminal (it doesn't matter which - although for clarity, not L, or N!).
This should link out the receiver, and allow you to Use the controls on the front of your boiler, to control the heating.

I know its not what you want to hear, but it is Salus, bin it and buy something decent, they are possibly the worst controls you could buy, they are absolutely dire
