I was hoping someone can help. We have Radio Teleswitch pictured below. Can anyone tell me what is the red button for please? I understand it says off/on but what does it do?
Couple of months ago one of my heaters broke down and I had a guy who came to fix it. He also fiddled with the radio tele switch and I suspect that he might have change something and the heaters now taking only the peak rates.
Can anyone advise please?
