The controller uses the regular minimum
ventilation speed when the outside tempera-
ture is at or above the summer's reference
temperature and uses the winter's minimum
ventilation speed when the outside tempera-
ture gets below the winter's reference tem-
perature. Refer to the User Setup menu to set
the summer & winter reference temperatures.
Note that the winter speed is related to the
regular speed. This means that if a change oc-
curs in the regular speed, the same variation
will be applied to the winter speed.

Normally, the winter's bandwidth should be
greater than the summer's bandwidth.
