Wall boilers

Wireless thermostat connection

Good morning to everybody. I ask you a question. I just installed a Euterma boiler in my house and now I have to place the wireless thermostat and the truth is how it is done. I am almost sure that it is on two wires that are sealed in the boiler's power cable (red and black bridged) attached photo ... The thermostat has 3 inputs (COM. NO. NC) attached photo. And the other issue is the thermostat current says ac220v would be straightforward but I don't want to risk burning the plate. Thank you very much already. regards https://ibb.co/gELtrx https://ibb.co/kNP8PH https://ibb.co/fLZ04H https://ibb.co/fNBDPH

Hi The thermostat is powered with 220 volts direct, in the terminal block indicated with L (line, or live, or phase) and N (neutral). Then in the cable that has a loop (room thermostat connection) in the boiler is sandwiched between C (common) and NO (normal open). When the circuit is closed, the boiler will turn on. It can occur from thermostats that work in reverse, in that case you must take C and NC. But they are the least. Regards !

Good afternoon. I was trying to connect the thermostat and there was no case ... I connected the two outputs of the boiler to NC and NO and the direct thermostat to 220 because I could not find the terminal block. If it is where the large plate is, I think I have to disassemble a lot to get to it ... It takes it to the thermostat but when it has to give the boiler spark to turn on the same short thermostat and only the fan remains. I am doing something wrong?
