1.Use only copper wire between the disconnect switch and the unit.

2.If any of the original wire, as supplied, must be replaced, use the same or equivalent type wire.

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

4.Blower motor speed selections are for average conditions. See Installation Instructions for details on optimum speed selection.

5.Replace only with a 3-AMP fuse.

6.Auxiliary limit switches (ALS1 & 2) used on some horizontal and some downflow models.

7.This wire must be connected to furnace sheet metal for control to prove flame.

8.Factory connected when LGPS not used.

9.Symbols are an electrical representation only.

10.BLOWER-ON DELAY: Gas heating 45 seconds, Cooling/Heat Pump 2 seconds.

11.Cooling/Heat Pump BLOWER-OFF DELAY is 90 seconds.

12.IGNITION-LOCKOUT will occur after four consecutive unsuccessful trials-for-ignition. Control will automatically reset after three hours.

13.Control must be grounded at pin 10 of 12-pin connector.

14.NA - Not Applicable

15.Spare terminal and wire not available on some applications. Insulate connector if not available.
