NOTE #10

1. If any of the original equipment wire is replaced, use wire rated for 105°C.

2. Use only copper wire between the disconnect switch and the furnace junction box (JB).

3. The wire must be connected to furnace sheet metal for control to detect flame.

4. Symbols are electrical representation only.

5. Solid lines inside PCB are printed circuit board conductors and are not included in legend.

6. Replace only with 3 amp fuse.

7. Inducer (IDM) and blower (BLWM) motors contain internal auto-reset thermal overload

switches (OL).

8. Neutral connections are interchangeable within the NEUTRAL connector block.

9. Blower motor speed selections are for average conditions. See installation instructions for

details on optimum speed selection.

1 0 . YELLOW lead not on all motors.

11. Factory connected when LGPS is not used.

1 2 . Ignition-lockout will occur after four consecutive unsuccessful trials-for-ignition. Control

will auto reset after three hours.

1 3 . Blower-ON delay, gas heating 25, 45 or 65 seconds, cooling or heat pump 2 seconds.

1 4 . Blower-OFF delay, gas heating 90, 120, 150 or 180 seconds, cooling or heat pump 90

seconds or 5 seconds when J2 is cut.
