BG was in my house and installed a room thermostat to my combi boiler worcester24CDi combi. For the last 4 days I am trying to work with it but the thermostat act weird. Lets say the house get worm and I click it off. On 21 degrees it will not click back on not even in the morning after. Like as if it not sensitive enough. I read here about the fact that there is an anticipator in the thermostat that make it think it is



1.5 degree wormer and that's what make the thermostat more sensitive. Is it true?

After check the wires I see that the guy connects only 2 wires and did not connect the N which mean the anticipator will not function. This is the model of thermostat that I have (RTS1)

don't know if it have an anticipator in it. And if I will connect the N will it help and make it more sensitive? Dose some one have that thermostat and can tell me?



Many Thanks

It looks like an elctromechanical type stat and has a neutral connection so there is a very strong likelihood that it has a compensator and will function better with a neutral. The lackluster performance you are getting would also suggest this.

Failing that fit a modern programmable stat that will work well without a neutral. e.g.:

Correct. Get BG back to do the job properly. This means either installing a three wire circuit or changing the thermostat for a solid state type which doesn't need a heater coil.

all points correct. Except your decision to let BG near your gas install.
