Thermostats in Belgium

Question

I want to replace an old thermostat. It is in the living room controlling something in the basement (Appartment building). Would like to know if the connection is likely to follow some kind of standard? Also if I might pull power from it?
Of course it is probably a wire-pair, but It is quite fixed, so I it is difficult to check.

You might want to hire a company such as Electricchauf that specializes in this sort of thing (www.electrichauf.be) unless you are quite experienced in such matters.

You would be extremely ill advised to change the apartment thermostat without first consulting with building management who own and manage the heating system of the building. Especially since it appears that your knowledge of such systems is relatively basic. "It is in the living room controlling something in the basement" (sic).

More info: The present thermostat relies on a battery. So it is clearly a low voltage connection.

@ANON: We own the gas heater in the basement. There is no "building management who own and manage the heating system of the building".

OK well with the additional clear information you've given, get a low voltage replacement thermostat and connect it to something in the basement.

I have done the replacement, it was just 2 wires, low voltage, as I though.

One issue is that wireless thermostats needs quite a bit of power. Nest for example can solve this by tricking by manipulating the HVAC to give it power, apparently this doesn't always work.

Another one is that the 2 wires are perhaps not equivalent.
