2.5 System set-up
2.5.1 Fan speeds
The control works with two different types of min/max limits:
1. Absolute fan speed min/max settings
Settings are factory set and cannot be changed. The fans are always operating within these limits
2. VOD fan min/max settings
These min/max settings are applicable when the unit works in VOD mode, but are always within the absolute
limits (no. 1). The limits will be corrected with the fan balancing offset (§ 2.5.2) if not zero.
2.5.2 Fan balancing
Fan balancing can be used to adjust the supply and exhaust air ratio. This can be done by changing
the parameter
offset
_
supply_exhaust_air.
 In case of a negative offset the exhaust fan speed is below the supply fan speed
 In case of a positive offset the exhaust fan speed is above the supply fan speed.
 When the offset is 0 the exhaust and supply fan speed is equal.
