Heat cur ve adjustment
You can "adjust" the heat curve up or down every fi fth outdoor degree.
For example, you can make a hump in the curve at 0ºC. Enter menu 1.3,
press Select and turn the menu dial until 0 is displayedºC in the upper
left-hand section of the menu. Then click on Adjust and turn the menu dial
to increase or reduce the return temperature. Adjust the temperature max
1-2ºC, then press Save and wait at least 24 hours. The purpose of breaking
the curve is to be able to infl uence the heat pump's heat production 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.
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. In
addition, special remote control equipment is needed. This equipment is
available as an accessory. 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.
