S9V2–VS Wiring Diagram
NOTES:
1. IF ANY OF THE ORIGINAL WIRING AS SUPPLIED WITH THIS FURNACE MUST BE REPLACED, IT MUST BE WITH WIRE HAVING A TEMPERATURE
RATING OF AT LEAST 105°C. WIRES 12, 48, 49, 50, AND 51 REQUIRE A TEMPERATURE RATING OF AT LEAST 250°C.
2. FOR PROPER AIRFLOW IN COOLING/HEAT PUMP MODES, Y1AND/OR Y2 MUST CONNECT FROM THE THERMOSTAT TO THE IFC LOW VOLTAGE TERMINAL STRIP.
3. FOR COOLING ONLY SYSTEMS, LEAVE Y1-O JUMPER IN PLACE ON THE IFC FOR CORRECT LED READOUT.
4. FOR HEATPUMP SYSTEMS, REMOVE THE Y1-O JUMPER, CONNECT "O" FROM THE THERMOSTAT TO "O" ON THE IFC LOW VOLTAGE TERMINAL STRIP FOR
CORRECT LED READOUT.
5. VSPD OD SYSTEMS REQUIRE DIFFERENT CONNECTIONS, SEE RELAY PANEL INSTRUCTIONS.
6. IF USING A SINGLE STAGE HEATING THERMOSTAT, JUMPER W1 AND W2 TERMINALS AT THE LOW VOLTAGE TERMINAL STRIP. HT2 WILL BE
SHOWN ON THE SEVEN SEGMENT DISPLAY AT ALL TIMES. SECOND STAGE OPERATION WILL BEGIN AFTER THE INTERSTAGE DELAY HAS COMPLETED.
7. AIRFLOW TABLES ARE LOCATED IN THE IOM. TO CHANGE AIRFLOW, REFER TO THE INTEGRATED FURNACE CONTROL MENU AND OPTIONS
TO SET AIRFLOW AND BLOWER DELAYS.
8. THE "BK" JUMPER MUST BE CUT WHEN APPLYING AN AIRFLOW COMMAND TO THE "BK" TERMINAL SUCH AS PULSE WIDTH MODULATION.
9. CORRECT PERSONALITY MODULE IS REQUIRED FOR PROPER FURNACE OPERATION AND IS SPECIFIC TO EACH MODEL AND SERIAL NUMBER. IT IS TO
REMAIN WITH THE ORIGINAL UNIT.
10. LINE CHOKE AND WIRE BK/28 ONLY USED ON MODELS WITH 1 HP MOTORS.
11. SOME MODELS WITH 3/4 HP MOTORS MAY USE JUMPER BETWEEN WIRES BK/27 AND BK/28.
12. WIRE YL/45 AND RAF-2 ARE NOT PRESENT ON DOWNFLOW MODELS.
