Thank you. The plumber checked the thermostat and the text display and said that there is a supply of electricity to the thermostat and to the text display. He will check again if the thermostat is stuck on the position inside...Or maybe a problem is in the box connecting he thermostat with the boiler?

i would check thermostat it may be stuck on the on position inside u will need to open it up and see if its stuck on. u can remove the thermostat wires and see if it still calls for heat then refit them back in the right place . THESE WIRES WILL BE LIVE AND WILL SHOCK U IF U DONT KNOW WHAT UR DOING. so best to call in someone that can do it for u like a electrican or plumber friend
