Negative Offset
Positive Offset
When VOD (§ 2.1.5) is selected the target fan speed applies to supply fan and is used as reference to adjust the exhaust
fan with an offset. The offset also applies to the minimum and maximum fan speed settings in such a way that always
an offset remains,

OFFSET
Supply Fan is adjusted because the limit of the fan MAX and MIN is reaches.
Negative Offset is Supply Fan LOW = Exhaust Fan + Offset
Positive Offset is Supply Fan HI = Exhaust Fan - Offset
The fan settings for LOW, MED, HI speed are applicable for the supply fan speed, in case of an offset the supply speed
is used as reference to correct the exhaust fan speed.
