2.
Tick “adjusting ventilation". The outdoor air
damper opens and the fan changes speed. The
compressor is stopped, if it is running, and the cir-
culation pump starts, if it is off.
3.
Measure the airflow at the ventilation device.
4.
If the ventilation flow is too high at outdoor air
mixing, reduce the fan speed.
5.
If the ventilation flow is too low at maximum fan
speed, restrict the outdoor air damper or reduce
the outdoor air damper's (QN38) degree of open-
ing using the stop screws on the damper motor.
If "red vent. at hi outd temp." is ticked, you can set "high
outdoor temperature" and how high the fan speed will
be at the selected temperature. This is to keep the in-
door temperature low at outdoor air temperatures
above the selected outdoor temperature.
NOTE
During high fan speed combined with a short
outdoor air duct, the total air flow can be
higher than the air flow sensor's (BS1) meas-
urement range. The heat pump then shows
the info text "Fan setting too high, reduce set
fan speed" and/or alarm "Err: BS1 air speed
sensor".
