Parameter Meaning
MAX Maximum calculated setpoint value of the supply temperature.
Factory setting: 55°C (for under floor heating 45°C), range: 40°C – 85°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
HEAT STOP Maximum outdoor temperature when heat production is permitted. If HEAT STOP applies,
the outdoor temperature must drop 3°C below the setting before HEAT STOP stops.
Factory setting: 17°C, range: 0°C – COOLINGMODE ACTIVE -3°C
CONSTANT TEMP The temperature that the shunt wishes to retrieve from the buffer tank and distribute to the
house. Only applies when the buffer tank is activated and with shunt group connected.
Factory setting: 18°C, range: 10°C – 30°C
SETBACK TEMP The temperature that will apply at temperature setback. Temperature setback is activated via
the calendar function. 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 sup-
ply 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
9.4 DISTRIBUTION CIRCUIT 1 - 2
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
