    Plumbing connections for accessories Safety group CAUTION Safety group must be installed in connection with hot water tanks. When water is heated to 60 °C, it expands by 2%. A pressured tank could burst without a safety valve keeping excess water out. The safety valve should therefore drip during warming up.

  • Page 31: Safety Group With Anti-Scald Protection

    Safety group with anti-scald protection In the control, a temperature limit for the domestic hot water of 65ºC is set as standard. This setting prevents scalding of the users when the hot water tap is opened. When the unit is in cooling mode, the energy is deposited in the hot domestic water tank instead of leading it out of the house. This also means that if the hot water temperature exceeds 65ºC, the unit stops cooling the supply air.
