Adapting the heat cur ve
You can "break" the heat curve up or down every fi fth outdoor degree.
For example you can make a hump in the curve at 0ºC. The purpose of
breaking the curve is to be able to infl uence the heat pump's heat produc-
tion at extra sensitive outdoor temperatures.
Room sensor infl uence
The menu is only shown for heat pumps having a room sensor installed.
You use the menu to set how much the room sensor should infl uence the
heat curve. A higher value will have a greater effect. Please note that the
room sensor only fi ne-tunes the heat curve. Consequently, it is important
the basic setting of the heat curve's slope and fi ne-tuning are correct.
Holiday function
The menu is only shown for heat pumps having a room sensor installed
and which are set to operating mode A. The holiday function gives you the
possibility to choose a number of days when the room temperature will be
lowered to 15ºC (the temperature is not adjustable). When the days have
passed the heat pump returns to the normal heating setting. Hot water
production is not affected by the holiday function.
Remote control
The menu is only shown for heat pumps having a room sensor installed
and which are set to operating mode A. In addition, special remote control
equipment is needed, this is available as an accessory. Remote control
cannot be combined with any other external control. You can switch
between the remote control mode and normal mode using a telephone.
Summer disconnection
The function means the heat pump only produces hot water when the
outdoor temperature rises above the set value. The function only works
when there is a hot water heater installed.
