12.4 OPERATING MODES
• With electric additional heat; the electric additional heat is
permitted to work at the same time as the heat pump to meet the
demand, when the heat pump cannot meet it by itself. Alarm mode,
Extra hot water and Hot water peak also activate the additional heat.
• With mixed additional heat (option); mixed additional heat which is
permitted to work at the same time as heat pump. The additional heat
is also used during alarm operation.
A hot water electric heater is required for production of extra hot
water and hot water peak. In this case, the electric additional heat in
the heat pump is disabled.

13.1 MODE BUTTON FUNCTIONS
By pressing , the following functions can be used directly:
• Room temperature normal / Temperature increase/decrease
• Party
• Holiday
• Extra hot water duration
> Room temperature normal / Temperature increase/decrease
Here, temperature changes for Circuit 1 can be made. If this circuit is
equipped with a room temperature sensor, the display shows Room
temperature normal , otherwise Temperature increase/decrease is
shown.
▶ Use this function to simply increase or decrease the heat when there
are no room controllers.
– – gives approx. 1 °C lower room temperature.
– gives approx. 0.5 °C lower room temperature.
+ gives approx. 0.5 °C higher room temperature.
++ gives approx. 1 °C higher room temperature.
> Party
Party mode means that a running room program is stopped during the
set time in order to avoid a temperature drop.
>> Number of hours
▶ Select the number of hours that party mode should be active for.
The function starts immediately on all activated circuits.
>> Circuit 1
>> Circuit x
▶ Select Yes to enable party mode.
Party mode can be enabled for each installed circuit. The menu is

Select Room temperature to adjust the heating.
The following options are available under Room temperature :
• Circuit 1 Heating
• Circuit 2, 3...
• General
> Circuit 1 Heating
>> Heat curve
The heat curve constitutes the basis for the control unit's control of the
temperature on the heating water to the circuit and indicates how high it
needs to be in relation to the outdoor temperature. The control unit
increases the temperature of the heating water when the outdoor
temperature drops. The temperature of the heating water out to the
circuit, i.e. the flow temperature is measured by sensor T1 for circuit 1
(full name E11.T1) and sensor T1 for circuit 2 (full name E12.T1).
The Multi module accessory is required for mixed
additional heat and hot water electric heater.
The button can be used to change the language of
the control unit.
▶ Hold down the
button for at least five seconds
in the initial menu and then select language.

Table 5 Room temperature increase/decrease
It always takes some time for a change of a heating
setting, e.g. an increase or decrease in room
temperature, to apply. The same applies in the event of a
quick change of the outdoor temperature. This is why
you should always wait for at least 24 hours before
making a new change.

Table 9 Extra hot water duration
After a period with blocked hot water production, e.g.,
holiday, it is recommended to enable the extra hot water
function so as to eliminate bacteria and quickly reach the
correct hot water temperature.
