8.3 Outdoor air temperature compensation
If the function is = 1 (on), the temperature set value is
displaced relative to the outdoor air temperature. The set
value displaced is the supply air temperature at supply air
regulation and exhaust air temperature at exhaust air
regulation. The temperature set value is increased if the
outdoor air temperature drops below +10°C according to
winter compensation curve or raises above 25°C according
to summer compensation curve. See diagram to the right.

8.2 Summer night cooling
At summer night cooling = 1 (on) the unit is operating on high
speed with a supply air of 10°C from 23.10 until the exhaust
air temperature is lowered.
Conditions which must be satisfied before the summer
night cooling function will start (at 23:10 hours):
– The exhaust air temperature should be above the preset
value (+24°C).
– The outdoor air temperature must be above the preset
value (+10 °C).
– The need for heating must have not existed between
12:00 and 23:00 hours.
– The unit must not run at high speed or be shut down by
means of pressing the manual stop button on the control
display or external stop.
Conditions which must be satisfied before the
summer night cooling function will stop:
– The exhaust air temperature must fall below the preset
value (+16 °C).
– The outdoor temperature must fall below the preset
value (10 °C).
– The timer or external input must call for high-speed
operation.
– The buttons on the control display will be influenced.
