9. Using the terminal block located on the electronic board, perform the low voltage connection
. Connection to a
low voltage power source is mandatory.
• Make sure that the polarity of the connections is respected.
• Pay special attention to the sensor located above the terminal block and the potentiometer buttons on the electronic board; they are very fragile,
do not damage them while performing the connections.
• Run the low voltage wires along with the other wires all the way to the hole and grommet in the housing, where the low voltage wires should
exit. Make sure that the wire seal foam is reinstalled.
NOTE:
If the unit is to be connected to a supply fan optional wall control, the low voltage wire should be connected to the terminal block now. Refer
to
(Connection to the Supply Fan Optional Wall Control on p8)
IMPORTANT:
Make sure that the wire seal foam is put back in place.
10. Reinstall the electronic compartment cover (make sure not to pinch wires), and set the Mode and Run time % buttons according to the settings
