For Integrated Control Motors (ICM)

To con®gure the 589A unit, move the 5 Easy Select board wires to the terminals which control the air¯ow. Refer to the Easy Select interface board (Fig. 22) located next to the terminals and to Fig. 30 and 32.

Perform the following steps for basic system con®guration.

AUX HEAT RANGE (VIO) Ð The air¯ow for unit 589A is preset at the factory. The air¯ow selection must not be set at a setting lower than the default. Refer to Table 15 for air¯ow and gas heat input for terminals 1-4.

AC/HP SIZE (BLU) Ð The preset factory default selection for AC/HP SIZE (air conditioner/heat pump) is set to 400 cfm/ ton. The selection pins are con®gured for 350 cfm/ton and 400 cfm/ton.

TYPE (ORN) Ð The TYPE is a preset factory default selec- tion. The preset factory default setting is AC for the 589A units. Default setting should not be altered.

AC/HP CFM ADJUST (BLK) Ð The preset factory default selection is MED. Selections HI and LO will adjust the air- ¯ow supplied for all operational modes (see following table).

The selection options allow installer to adjust air¯ow to meet such individual needs as noise and static compensation, etc.

MODE	FAN ONLY	COOLING	HEATING
LO - Adjust	−15%	−10%	−10%
HI - Adjust	15%	10%	10%

AC/HP TIME DELAY (GRY) Ð Four motor operation delay options are provided to customize system operation. See table below:

OPTION	TERMINAL	DESCRIPTION
		Used when it is desirable
30-Sec On/60-Sec		to allow system coils time
	1	to heat up or cool down
Off Delay Pro®le
		prior to air¯ow. Enhances
		system efficiency.
		Preset factory default setting for
		589A. Used for servicing or
No Delay Option	2	when other components are
		used to perform a delay func-
		tion (e.g., integrated gas
		control).
30-Sec Off Delay	3	Enhances system efficiency.
45-Sec Off Delay	4	Enhances system efficiency.
