Hi... I've just installed a Salus RT500RF. The heating comes on and off, when I raise and and lower the temperature on the thermostat, as you would expect. I've set all the timers to 5 degrees, as I don't need use of the timer function. All was fine till I came home today, to find the house was like a furnace. The heating had been on. When I checked the thermostat, the temperature override was at 22 degrees, give or take a degree. I had left it at 5 degrees that morning. I put the thermo back down to 5 degrees and left it. I nipped out for a few hours, when I came back, the house felt hot, but rads were near enough cold, so I can't tell if the heating had been on... However, when I pressed the down arrow, on the thermo, it showed 21.5 degrees. I've changed the pins, on the back of the controller, and thermo, and reset them both, by killing all power to them, for a minute, just in case there is another device interfering with mine. Can anyone explain why the thermo, is going back to a temp override temperature of 22 degree? I've found if I put the box to sleep, then turn it back on the override time will go back to 22 degrees also. The thermo has brand new Duracell batteries in. I have also got the operating instructions, it doesn't cover anything on this subject. Any help or advice is welcome.
