1 Warnings Danger • Make sure that the Mains supply to the unit is disconnected before performing any maintenance or electrical work! • All electrical connections must be carried out by an authorized installer and in accordance with local rules and regulations. • Beware of sharp edges during mounting. 2 Install the pressure transmitter Remove the supply air fan (figure 1). Caution If the unit is already installed in false ceiling, make sure that the fan does not fall down when removing the supply air fan.
Fig. 2 Mount the enclosed CAV pressure transmitter (PTS) in the pre-punched holes (figure 2, pos 1). Pos 2 only used for units with built-in electrical heater e.g. Topvex FC04 EL.
3 Wiring Convert Topvex FC to a CAV unit by connecting CAV pressure transmitter (PTS) to the pre-wired tubes and electrical cables. For units with electrical heater (EL) the tube from the Flow guard (AFS) to the Supply fan (SF) inlet cone must be cut and connected to the new CAV Pressure transmitter (PTS) by the enclosed Y-connector. Terminals in the unit are addressed to following terminals in the actual pressure transmitter (see wiring diagram/wiring chart for actual unit).

Sensor setting. Set the adjusted working range for the added CAV pressure transmitter in menu Configuration/Sensor setting. Adjust SAF (supply air fan) and EAF (extract air fan) actual pressure range at 10,0 V. Example Topvex FC02: If pressure transmitter is set to 0...1000 Pa set: 0,0 V: 0,0 Pa and 10,0 V : 1000,0 Pa. Filter factor is not to be changed.
