Has it ever worked?

Customer: replied 1 year ago.
I bought the house last year from my parents and the new system was installed the year before that.
Parents had the heating on 24/7 so I don't know.

Forgot to mention, Both of them passed away last year so I can't ask them.

Would you like a link to the instructions?

Can you upload a picture to confirm which model?

Customer: replied 1 year ago.
The wireless thermostat is the Salus ST620RF I already have the instructions and have done exactly as instructed, even paired the sender and receiver, I believe how this system shuts on and off is by the temperature that is set, room temperature at 21° at the set time to come on and 10° at the set time for off which would also be the night time setting during sleep,
I set the receiver to auto on top switch and on, on the other.The darker picture of the receiver is to let you see the colours it was flashing.
