The control is suitable for use with Direct-Drive PSC motors
and ECM motors. ECM motors can be controlled in the
common “thermostat-mode” or with other innovative and
optional methods. PSC motors are controlled with traditional
heavy-duty relay outputs, but can also be controlled in a
variable speed method using the optional low-cost plug-in
adaptor.

NOTE: FOR 2-STAGE COOLING IN ENHANCED
MODE USE YX AND Y2. YX IS A DUMMY
TERMINAL AND IS IGNORED BY THE CONTROL
LOGIC BUT PROVIDES A CONVENIENT
CONNECTION POINT FOR THE AC
COMPRESSOR. WHEN THE THERMOSTAT
CALLS FOR STAGE 1 COOLING (A Y1 SIGNAL
FROM THE THERMOSTAT) IT IS TERMINATED
AT YX, BUT THE THERMOSTAT ALSO
ACTIVATES G SIMULTANEOUSLY. THE 9103I
THEN ENERGIZES THE LOWER SPEED HEAT
TERMINAL AS LONG AS THE CONDITION
EXISTS. IF Y2 IS ENERGIZED (TOGETHER WITH
Y1/G, OR SEPARATELY) THE CONTROL WILL
SWITCH TO THE HIGHEST SPEED. THIS

•
Cooling: Blower is initially started on Lower
Speed for 4 minutes to allow for
dehumidification, after which the blower
switches to Higher Speed. If the the 24VAC
signal to the DH terminal opens this signals
a call to dehumidify and the blower drops
down to Lower Speed to encourage greater
condensation across the cooling coil. When
the 24VAC signal reappears on DH the
blower is switched back up to Higher Speed
◦ Y1 (24V signal): 4 minutes at Lower
speed to dehumidify, then to Higher
speed
◦ DH (NO 24V signal): immediately
drops from Higher speed to Lower
speed to dehumidify.
◦ DH (24V signal returns): Blower
stepped up to Higher Speed
◦ Y2 (24V signal) overrides DH and Y1
keeping Higher Speed energized as
long as signal on Y2 is present
◦ G (24V signal alone without Y1, Y2, or
W): energizes Lower Speed terminal

For Enhanced PSC Direct Drive

ECM Mode:

ECM Motor handles all blower speed logic in factoryset “thermostat mode” and it monitors all ten
thermostat inputs. The 9103i control continues to
energize the Burner, EAC and H terminals normally.
While the DIP-Switch settings are now directed to
the ECM motor through the 16-pin connector the
9103i will continue to interpret the BOD settings to
establish the delay period before de-energizing EAC
terminal. Please note that the OEM factory -settings

with the EAC delay.

PSC (Direct Drive) Variable Speed
Mode:
A compatible Direct Drive PSC blower motor is
driven by optional plug-in ACC001 PSC Motor
Speed Control Module in conjunction with Dip-switch
settings. Heat and Cool outputs on the 9103i are
routed through the speed control module to the
appropriate windings on the blower motor. The
module reduces the line voltage delivered to the
blower thereby slowing according to the userselectable Dip Switch settings allowing fine-tuning of
blower speed in Heat and Cool operation.

PSC “eTemp” (Direct Drive)
Temperature-Modulation Mode:
A compatible PSC blower motor is driven by optional
plug-in ACC001 PSC Motor Speed Control Module
in conjunction with a ACC003 Plenum Temperature
Sensor. Heat and Cool outputs on the 9103i are
routed through the speed control module to the
appropriate windings on the blower motor. The
module reduces the line voltage delivered to the
blower thereby slowing it to maintain a speedtemperature relationship.
Speeds are derived from the delivered air
temperature (TARGET TEMPERATURE) as sensed
by the plenum sensor and modified by DIP-switch
settings.

IN COOLING MODE A LOW TEMPERATURE LIMIT OF 45
DEGREES F IS FIXED. IF THE PROBE DETECTS A
CHILLED AIR TEMPERATURE BELOW THIS LIMIT THE
BLOWER WILL OPERATE AT 100% FULL SPEED TO
PREVENT DAMAGE TO THE COOLING SYSTEM.
STEADY STATE TEMPERATURES WILL BE DEPENDENT
ON VARIABLES SUCH AS BLOWER-DESIGN, DUCT
WORK, BURNER FIRING-RATE, AC TONNAGE, ETC.
AFTER REACHING A STEADY STATE TEMPERATURE
THE INSTALLER SHOULD ADJUST THE DIP-SWITCH
SETTINGS TO ACHIEVE THE IDEAL TEMPERATURE
FOR THE EQUIPMENT IN BOTH HEATING AND
COOLING MODES
