Central heating not turning off

jav277 · Nov 4, 2020

Hi

I'm having a problem turning my central heating off. My indoor thermostat shows the heating is off, even though it is still on. There is an Altech receiver box next to our combi boiler which constantly has the green light on which tells the boiler to turn the heating on. I can only turn off the central heating by turning the receiver box off completely which can be a pain due to the location of the boiler.

This problem occurred last year too. We then had our boiler serviced and our plumber fixed the issue temporarily. He said the connection was lost between the Altech receiver and Altech thermostat.

Please could I have some help on my problem?

Thanks in advance for any replies.

Try re synching the units first. Google it for your particular model.

Hi

Thank for the reply. I don't believe there is a way to re sync my thermostat and receiver. I cannot find anything online for the model I have. I will post pictures on here.

It's a rebadged salus thermostat.

Try dropping the temp below current. Wait 10 seconds then increase it again.

Failing that look up salus thermostat.

Have to agree older salus stuff was a bit clunky latest range well we have fitted over 60 of the 520rf only one changed was chewed by end users dog!
Easy to fit and set up
