NOTES:
1. Use only copper wire between the disconnect switch and the furnace.
2. If any of the original wire, must be replaced, use the same or equivalent type.
3. Inducer (IDM) motor contains internal auto-reset thermal overload switch.
4. Blower motor airflow selections are for nominal conditions. See Installation
Instructions for details on optimum airflow selections.
5. Blower motor (BLWM) is locked-rotor overload protected by redundant
electronic control circuits. Restart is attempted every 15 seconds for 2 minutes,
after which it locks OFF. Reset by turning OFF all control and/or power inputs.
6. Replace only with a 3-AMP fuse.
7. Auxiliary limit switches (ALS1 & 2) used on some horizontal and some
downflow models.
8. This wire must be connected to furnace sheet metal for control to prove flame.
9. Factory connected when LGPS not used.
10. Symbols are an electrical representation only.
11. BLOWER-ON DELAY: Gas heating 45 seconds, Cooling/Heat Pump 2 sec.
12. Cooling/Heat Pump BLOWER-OFF DELAY is 90 seconds.
13. IGNITION-LOCKOUT will occur after four consecutive unsuccessful
trials-for-ignition. Control will automatically reset after three hours.
14. Control must be grounded at pin 10 of 12-pin connector.
15. Inductor is used on 060 or
- 20 cooling airflow size furnaces only.
PL5 connectors are joined without IND on other furnace sizes.
16. Twinning is not permitted with ICM2 + blower motors. Keep twinning jumper in
MASTER position.
17. Terminals (HI-COOL, HI-GAS-HEAT, and LO-GAS-HEAT) are not used for
ICM2 + BLWM. Do not remove electrical insulators.
COMPONENT TEST
To initiate the component test sequence with no thermostat inputs and
with all inducer Post-Purge and Blower-Off Delay periods completed,
short the "TWIN/TEST" terminal to the "
C OM" terminal for about two
seconds. The control will turn ON the inducer motor Low-Speed, inducer
motor High-Speed, HSI, blower motor Continuous-Fan Speed, blower
motor High-Gas-Heat Speed, and blower motor High-Cool Speed for
7-15 seconds each. Neither the gas valve nor the humidifier will be
turned ON.
