Firebird S 90 wiring thermostat

Hello

i just moved in a house with a firebird S boiler.

the boiler works well but I can’t manage to get the room thermostat to work.

I eve wonder if they are connected. Do you know where I can find the wiring diagram of the control panel. The one on the firebird web site doesn’t match what I have.

Put up some photos. Beware often these use main's voltages and can easily kill.

Hello, here are some photos.

First the front panel

Then, the valves and pump. The blue one makes some noises from time to time.

Then inside the panel

With timer switch on, if I ask the thermostat for higher or lower temperature, it is ignored.

With timer switch off, if I ask the thermostat for higher or lower temperature, it is ignored.

I am starting to wonder if the room thermostats are even wired properly. I can't trace them as coming to the front panel.

Please note, the boiler manual doesn't show the same front panel, it also doesn't show the same wiring at all.

The thermostats should control the valves and are probably wired to a junction box close to them
