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.

Check the ratings and specifications given in the Instructions and on the product to assure the product is suitable for your application. 3. Installer must be a trained, experienced service technician. 4. After installation is complete, check out the product operation as provided in these instructions. 4 CAUTION Disconnect power supply before wiring to prevent electrical shock or equipment damage. Location and Mounting The 9103i is mounted in the appliance wiring compartment using four No. 6 screws (obtained locally) through standoffs on the corners of the board. is used in PSC or BLDC Variable Speed Modes the control immediately recognizes it and will begin to adapt the variable speed operation to Temperature Modulation Mode. If the sensor is unplugged at any time the control reverts back to normal Variable Speed Mode. Wiring All wiring must comply with local codes and ordinances. Disconnect power before making wiring connections.

The factory-default has the jumper in the upper-most position indicating Standard operation (No options enabled). Position F1 enables the variable speed PSC option. F2 enables the Enhanced PSC (Direct Drive) features. F3 is reserved for OEM-specific customization. See OEM furnace guide for details of this feature. PSC-Variable F1 Speed Mode F2 F3 PSC Enhanced Mode F1 F2 F3 OPERATIONAL MODES: All operational modes are simultaneously active on the 9103i, and the user needs only to make the appropriate connections to make use of them. The DIP-Switch is interpreted by the on-board software differently for each mode of operation. Custom Furnace-OEM Program F1 F2 F3 Whenever the optional plenum temperature sensor 5 Speed (Speed2/Cool Speed) Standard PSC (Direct Drive) Mode • • Blower motor is driven by on-board heavy duty relays. Heat, Cool and Continuous speeds are available from 0.250” male spade terminals clearly marked on board. Compatible with all 5+ wire thermostats and responds to: ◦ W: heating ◦ Y1: cooling ◦ Y2: cooling ◦ G: Blower On ◦ DIP-Switch: ▪ Blower Off Delay (BOD): • A: 90 Seconds • B: 120 Seconds • C: 150 Seconds • D: 180 Seconds ▪ Heat: no function ▪ Cool: no function ▪ Adj: no function jumper NO OPTIONS SELECTED 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 ALLOWS FOR 2 DIFFERENT BLOWER SPEEDS FOR 2-STAGE COOLING F1 F2 F3 Option Jumper For Standard PSC Direct Drive mode ensure that Jumper is in default “No-Option” position Enhanced PSC (Direct Drive) Mode Selected by placing the option jumper across position # F2 on the Option Select pins (See “Setting Options”). All wiring and connections remain the same as the Standard PSC mode, however the operation is enhanced. ATTENTION: ENABLE THIS OPTION ONLY WHEN THE COOLSpd 2 TERMINAL IS CONNECTED TO A HIGHER BLOWER SPEED THAN HEAT-Spd1 OUTPUT. jumper F1 F2 EXAMPLE: “HEAT-Spd1” CONNECTED TO MEDHIGH “COOL-Spd2” CONNECTED TO HIGH • 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 F3 Option Jumper For Enhanced PSC Direct Drive mode ensure that Jumper is in F2 position Heating: ◦ W (24V signal) activates Lower Speed (Speed1/Heat Speed) output ◦ W+W2 (24V signals) activate Higher 6 Blower Wiring: Standard and Enhanced PSC (Direct Drive) Modes 120 VAC internal connection 24 VAC internal connection 120 VAC external wiring 24 VAC external wiring Unused Motor Speed Continuous speed Continuous Fan Switch (Optional) Heat speed Multi-Speed PSC Blower Cool speed Neutral N 4 1 Spare 7 8 Cool Heat EAC Cont 2 3 6 X C 9 BURNER (Alternate) L1 24 VAC Transformer Snsr Vsp G W R Y1 C W2 Y2 YX O DH 7 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 for the ECM blower-off delay may not co-ordinate with the EAC delay. jumper NO OPTIONS SELECTED F1 F2 F3 THE 9103I CONTROLLER HAS NO INFLUENCE OVER THE ECM MOTOR AS ALL SIGNALS ARE “PASS-THROUGH” ONLY.

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. jumper F1 F2 F3 REFER TO SPEED CURVES FOR MORE INFORMATION ON TEMPERATURE-SPEED RELATIONSHIP Option Jumper For PSC Variable Speed mode ensure that Jumper is in F1 position Speeds are derived from DIP-switch settings (SEE .

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.

UNDER NORMAL CIRCUMSTANCES THE BLOWER WILL FIND A STEADY-STATE HEATSPEED AT A TEMPERATURE LOWER THAN THE TARGET, AND FIND A STEADY-STATE COOL SPEED AT A TEMPERATURE HIGHER THAN THE COOLING TARGET TEMPERATURE. 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 RECIEVE 100% FULL LINE VOLTAGE TO PREVENT DAMAGE TO THE COOLING SYSTEM. STEADY STATE TEMPERATURES WILL BE DEPENDENT ON VARIABLES SUCH AS LINE VOLTAGE, BLOWERDESIGN, DUCT WORK, BURNER FIRING-RATE, AC TONNAGE, ETC.
