Salus RT500 RF problem.

[trigger25]

I've only been at my present house just over a month and last night I found the central heating was still on at 3.30am which is way after the programmer should have made it go off. I have programmed the remote unit as per the manual and the 5th and last setting was set to 10 degrees which means the CH shouldn't be on. It hasn't done this before as far as I can tell.

The boiler is a Vaillant ecoTECH Pro 28 and the programmer is a Salus RT500 RF. I have reset the programmer and changed the batteries and sat by the boiler which is in the loft and it appears to switch on and off OK when I manually adjust the temperature set point. It also switches the boiler off when I put the programmer to sleep. Apart from altering the RF switches and links is there anything else I can do without changing the programmer for another brand.

Any advice gratefully appreciated.

try altering the Dip switches. The stat comes without any changed/removed and it is possible that you have something near by that is on the same frequency as you have and is turning it on and off. I have known it happen quite a few times and is worth checking

Was it too hot in the house ?, in this cold weather -3 outside and non perfect insulation
our heating has been set for a night time top up ! before Full heat in the morning !
( especially if a bathroom window is left a jar ) Maybe you reached the 10 degrees limit ?

I did wonder about the 10 degree settings and have now set them to 7 degrees as a test. As johnf also suggested I will change the RF DIP switches and links as a final test and if that doesn't work the I'll have to think about a replacement programmer.

If controller link is broken , some get stuck in current condition .
So house should either be too hot or too cold - and a change may be best !

( don't put Wifi routers / Phone hot-spots too close to receiver on boiler )

Occasional outages should go un-noticed (unless watching carefully)

does the display glow blue when pressed?
perhaps batteries need changing!!

A lot of these Salus' have these problems

That was one of the first things I did. Thanks.

Having trawled the internet I can see they have had problems. I also looked at some Honeywell ones in case I need to change it. Some of them had disappearing LCD displays.
Any suggestions for alternatives to mine would be most welcomed. Thanks

I would say the Honeywell ones are much better

try the batteries again, sometimes they dont sit right and make a buzzing sound. make sure the display is blue !!
