Operating mode according to curve
Relates to parameters 3, 4, and 5.
• When operations according to the heating curve are enabled
(parameter 3 = 1), the set point temperature in heating
mode, hot tap water + heating mode as well as mode hot
tap water + auto are controlled as a function of the current
outdoor temperature. A higher outdoor temperature gives a
lower set point temperature in heating mode and vice versa.
• The highest set point temperature for heating is 50°C.
• Use parameter 4 to set the required heating curve. There is a
total of 15 possible curves.
• The diagrams denote the highest set point temperature for
each curve

FIG. 36
• Parameter 5 is used to change the set point temperature set
in accordance with the selected heating curve. The actual set
point temperature will then be the set point temperature
according to the heating curve + the correction value from
parameter 5.
Example
• Parameter 3 is set to 1, operations according the heating
curve is enabled. The set point temperature for heating is
adjusted according to the heating curve, as a function of the
current outdoor temperature.
• Set parameter 4 (heating curve) to 9, set parameter 5
(correction value) to 2.
• Profit
– When the outdoor temperature is -12 °C the set point
temperature for heating is (50 + 2) °C.
– When the outdoor temperature is 0 °C the set point
temperature for heating is (40 + 2) °C.
– When the outdoor temperature is 10 °C the set point
temperature for heating is (32 + 2) °C.
Parameter setting
1. When the heat pump is in standby mode or working, press
and hold SET and
O
for 5 seconds to check the parameter
setting.
2. Press or to check the parameter values in sequence.
3. Press SET. The parameter value flashes. Press or to
increase or decrease the parameter value.
