I had a Flomaster remote thermostat fitted to my Heatline C24 combi by my plumber a few months ago. Apart from never really liking the interface as it seems fiddly and complex to program, I noticed that even though it was set at 17 degrees, the central heating was on even though the temp was showing it was 19 degrees. As the boiler is permanently set to on (on it's manual clock) for central heating, I usually manually turn the thermostat on and off to save the headache of programming the timer. However, I switched the thermostat off but the boiler stayed on. The only way to get it to switch off was to turn the mains switch off after turning the clock on the boiler off. I turned it back on and also the thermostat and it didn't turn on. Earlier I dropped the thermostat on the floor but it wasn't a heavy drop as it was carpet. Could this have upset it ?
What I have also come to dislike with this thermostat is the fact that, when running normally, it doesn't swich off at the required temp until it's gone quite a bit higher. There are increments of 0.5 degrees so it should be that accurate. If I say set it for 20 degrees it would perhaps run until 20.9 which to me isn't economical. In fact, since getting a thermostat I haven't seen reductions in my bills as forecast.
Now I am reluctant to go out the house and leave the boiler mains swich on incase it happens again and runs us up a bill.
