sufficient, remove other cable knock-outs with a
screwdriver to install extra-cabling.
2.4.1.1 - 115 VAC (terminals 11 and 12)
Make sure that the line voltage selector switch is set to
115 VAC
. Connect the power cable to terminals 11 and 12
on the main (bottom) board, connect the ground wire to
terminal 13 on the main board .
2.4.1.2 - 230 VAC (terminals 11 and 12)
Make sure that the line voltage selector switch is set to
230 VAC.
Connect the power cable to terminals 11 and 12
on the main (bottom) board, connect the ground wire to

2.4.4 - Fan 3/Heater
Stage 3 provides a dry contact which controls the operation
of a third single speed fan or a heater. This contact closure
is voltage rated to 230 VAC. The current rating of the dry
contact is 10 Amps (resistive) for a heater and 6 Amps
(conductive) for a fan. Set the software settings DIP switch
behind the control panel faceplate to ON for a fan or OFF
for a heater.
