4.5 Supply air sensor
The supply air sensor is fitted in the duct ca. 3 m after the unit in the supply air duct (figure 10). See
table 4 to which terminals the sensor needs to be connected in the electrical connection box. Other
temperature sensors are built in to the unit from factory. The supply air sensor is enclosed in the unit
package on delivery.

4.6 Installation of VAV models
If the unit is delivered as a VAV (Variable Air Volume) unit the pressure transmitters controlling the fan
speeds are delivered loosely with the unit. The pressure transmitters need to be mounted in the supply
and extract air ducts (figure 11) and connected to terminals 40–42 (table 4).
