Parameter Meaning
SETBACK TEMP The temperature that will apply at temperature setback. Temperature setback is activated via the calendar func-
tion. When the function is activated ROOM is the temperature that is set here.
Factory setting: 18°C, range: 10°C – 30°C
ROOM FACTOR Only displayed if an accessory Room temperature sensor is installed. Determines how great an impact the room
temperature is to have when calculating the supply temperature.
For under floor heating it is recommended that ROOM FACTOR is set to 1, 2 or 3.
For radiator heating it is recommended that ROOM FACTOR is set to 2, 3 or 4.
Impact: 0 = no impact, 4 = large impact.
Factory setting: 2, range: 0 – 4
HIGH POWER If HIGH POWER is ON, the unit will run frequently at higher compressor frequency and fan speed.
If HIGH POWER is OFF, the unit will run more frequently at reduced compressor frequency and fan speed, mak-
ing the unit more quiet. Compressor and fan will increase speed if there is demand for it and will increase speed,
on compressor and fan, before the auxiliary heater starts.
Factory setting: OFF

Only appears if the function is activated in menu SERVICE -> INSTALLATION - SYSTEM -> SHUNT GROUP.
Parameter
Meaning
CURVE Calculated supply temperature at 0°C outdoor temperature. Shown as a graphic curve. The curve will be limited
by the set values of MIN and MAX.
Factory setting: 40°C (for under floor heating 30°C), range: 22°C – 56°C
MIN Minimum permitted supply temperature, if the temperature for heat stop has been reached and the heat pump
has stopped.
Factory setting: 10°C, range: 10°C – 50°C
MAX Maximum calculated setpoint value of the supply temperature.
Factory setting: 55°C (for under floor heating 45°C), range: 15°C – 70°C
CURVE +5 Local increase or reduction of CURVE at an outdoor temperature of +5°C. Shown in the graph for CURVE.
Factory setting: 0°C, range: -5°C – 5°C
CURVE 0 Local increase or reduction of CURVE at an outdoor temperature of 0°C. Shown in the graph for CURVE.
Factory setting: 0°C, range: -5°C – 5°C
CURVE -5 Local increase or reduction of CURVE at an outdoor temperature of -5°C. Shown in the graph for CURVE.
Factory setting: 0°C, range: -5°C – 5°C
DURING COOLING During production of cooling the shunt group can be adjusted.
Factory setting: AUTO, range: AUTO, OPEN, CLOSED
CONSTANT TEMP Controlling the shunt group against a constant temperature is an alternative to the control using a heat curve
given above. Control using constant temperature is selected using the parameter CONSTANT TEMP in the Serv-
ice menu.
Factory setting: 40°C, range: 10°C – 55°C
SETBACK TEMP The temperature the shunt group works with when the temperature reduction is activated in the menu CALEN-
DAR.
Factory setting: 18°C, range: 10°C – 30°C
ROOM FACTOR
(Distribution circuit
1 only)
Only displayed if an accessory Room temperature sensor is installed. Determines how great an impact the room
temperature is to have when calculating the supply temperature.
For under floor heating it is recommended that ROOM FACTOR is set to 1, 2 or 3.
For radiator heating it is recommended that ROOM FACTOR is set to 2, 3 or 4.
Impact: 0 = no impact, 4 = large impact.
Factory setting: 2, range: 0 – 4
