Function description

The heat pump has an integrated control system that is used to automatically calculate the heat demand in the house
where the heat pump is installed and to ensure that the correct amount of heat is produced and emitted where neces-
sary. There are many different values (parameters) that must be referred to during the calculation of the heat demand.
During installation and service, the control panel is used to set and change values that have to be adapted according
to the house demand. The control panel is integrated into the front of the heat pump and consists of a display, a key-
pad and an indicator. In the display, a simple menu system is used to navigate the desired settings and values. During
operation, the display always shows the set ROOM value, the operating mode and the status of the heat pump.
Indicator
The control system is controlled using a user-friendly menu system, which is shown in the display. Use the key-
pad's four navigation symbols to navigate the menus and increase or reduce the set values:
The menu, INFORMATION, is opened by pressing the left or right buttons. The INFORMATION menu has a
number of sub menus that are described in section 13 Menu information.
For installation and service, the hidden menu, SERVICE, is used. This is opened by holding the left button
depressed for five seconds. The SERVICE menu has a number of sub menus that are described in section
13 Menu information.
The INFORMATION and SERVICE menus are intended for two categories of user, end customers and installers.
End customers may only open the INFORMATION menu with a limited number of settings whilst installers have
to change many settings in the control settings. The SERVICE menu is therefore hidden from end customers.
