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)

And more info here

I 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.

so if i get one of the digital ones i dont need to wire the neutral at
all ??

If battery operated, no.

The manual on that page shows that it has a C/O relay as output, and is
battery powered, so yes ...

yup. its a compensation resistor.

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