Heating
The apartment is heated by a floor heating system, to regulate the temperature you have to use the thermostat which is located near the entrance.
Air conditioning
To turn on the air conditioning and adjust the temperature there is a remote control.
Water heater
If the temperature does not increase and the water in the kitchen/bathroom is cold it may be necessary to fix the water heater which is located in the storage room, near the kitchen. Check the pressure which should be equal or higher than 1 bar. If the pressure is lower than 1 bar check the lower part of the water heater and find the black knob to regulate water pressure. Turn the knob until the pressure is 1 bar.
If the water is still cold the water heater may be blocked, then push the reset button. It’s located on the wall.
