CE Series Heat Pump6 720 220 048 (2014/08) Subject to change without prior notice
This LED indicates the air delivery of the blower at
any given time. Each blink of the LED represent
approximately 100 CFM of air delivery so if the LED
blinks 12 times, pauses, blinks 12 times, etc. the
blower is delivering approximately 1200 CFM.
Refer to Figure #9 for factory programmed air
delivery settings for the CE Series.
To the right of the thermostat connection block is
a green LED labeled dehumidify.
Just above and to the right of the thermostat connection
block are four sets of jumper pins labeled ADJ,
DELAY, HEAT and COOL. The ADJ set of pins are
labeled NORM, (+), (-) and TEST. CE units will all
be set on the NORM position from the factory,
however, airflow can be increased (+) or
decreased (-) by 15% from the pre-programmed
setting by relocating the jumper in this section.
The TEST position is used to verify proper motor
operation. If a motor problem is suspected, move
the ADJ jumper to the TEST position and energize
G on the thermostat connection block. If the motor
ramps up to 100% power, then the motor itself is
functioning normally. Always remember to replace
the jumper to NORM, (+) or (-) after testing and
reset the unit thermostat to restore normal
operation.
The other DIP switch bank is used to select the
proper program in the ECM motor for the unit.
Refer to Figure #7 for the proper jumper
placement.
To the left of the red and green status LED’s is a
row of 1/4” male quick connects. These are used
to pass thermostat inputs on to the rest of the
control circuit.

Just above the connector block is a single red
LED labeled CFM that will blink intermittently
when the unit is running and may flicker when
the unit is off.
Do not set the ADJ DIP switch to the (-)
setting when electric heaters are installed.
Doing so may cause the heaters to cycle on
their thermal overload switches, potentially
shortening the life of the switches.
WARNING: Always disconnect power
before changing jumper positions on the
interface board and reset the unit
afterward.
WARNING: Remember to always turn
off unit power at the circuit breaker
before attaching or disconnecting any
wiring from these connections to avoid
accidental short circuits that can
damage unit control components.
