Menu information

The heat pump has an integrated control system which automatically calculates the heat demand in the house to ensure that the cor-

rect amount of heat is produced and emitted when necessary.

The control system is operated using a keypad and information is shown in a display and by an indicator.

N

The information in the display and menus will vary depending on heat

pump model and connected accessories.
