are provided to adjust airflow supplied to meet individual instal-
lation needs for such things as noise, comfort, and humidity
removal. (See Fig. 19, D as indicated.)
ON/OFF DELAY - SELECT DESIRED TIME DELAY PROFILE
Four motor operation delay profiles are provided to customize and
enhance system operation. (See Fig. 19, E as indicated)
Selection options are:
1. The standard 90 sec off delay (Factory setting) at 100 percent
airflow.
2. No delay option used for servicing unit or when a thermostat
is utilized to perform delay functions.
3. A 30 sec on delay with no airflow/90 sec off delay at 100
percent airflow profile is used when it is desirable to allow
system coils time to heat-up/cool-down in conjunction with
the airflow.
4. ENH, enhanced selection, provides a 30 sec on delay with no
airflow/ plus 150 sec at 70 percent airflow/ no off delay for
added comfort. This profile will minimize cold blow in heat

1. LO speed - factory setting, 50 percent cooling mode airflow.
2. MED speed - move connector to MED, 65 percent cooling
mode airflow.
3. HI speed - move connector of HI, 100 percent cooling mode
airflow. (See Fig. 19, F as indicated.)

LOW-VOLTAGE CIRCUIT FUSING AND REFERENCE

The low-voltage circuit is fused by a board-mounted 5-amp
automotive fuse placed in series with the transformer SEC2 and
the R circuit. The C circuit of the transformer is referenced to
chassis ground through a printed circuit run at SEC1 connected to
metal standoff marked with ground symbol.
BASIC FAN COIL CONFIGURATION
The following basic configuration of the fan coil will provide ARI
rated performance of the heat pump:
