Units supplied with internal electric heat
require two (2) separate power supplies: one
for the unit compressor and one for the electric
heater elements, blower motor and control
circuit. Refer to Figure #7 for wiring instruc-
tions, minimum circuit ampacities and maxi-

1. For the condensate overflow sensor, connect
'CS' at the condensing section to 'CS' at the
air handler. Be sure to ground power supply.
2. If service LED is utilized connect 'ALR'
terminal on the UPM board to 'L ' on the
thermostat sub base. The wiring may be
spliced in the air handling unit. The 'ALR'
output is hot (R) so check thermostat
instruction manual to ensure compatibility.
3. 'O' – reversing valve is energized in the
cooling mode. Fail safe is to heating.
4. Utilized when electric strip heater
package present.
