will run the higher of heat pump efficiency airflow and electric
heater airflow. The factory selection is largest heater range
approved. (See Fig. 16.)
B.
AC/HP Size
The factory setting for air conditioner or heat pump size is largest
unit meant for application with model of fan coil purchased. The
installer needs to select air conditioner or heat pump size to ensure
that airflow delivered falls within proper range for size of unit
installed in all operational modes. (See Fig. 16.)
C.
System Type
The type of system must be selected.
1. AC—air conditioner
2. HP-COMFORT—provides same airflow as air conditioner
selection (approximately 375 CFM/ton)
3. HP-EFF—provides most efficient airflow for heating and
cooling modes (approximately 410 CFM/ton heating and
375 CFM/ton cooling)
The factory setting is AC. (See Fig. 16.)
D.
AC/HP CFM Adjust
Select low, medium, or high airflow. To provide any of these
airflows, AC/HP ADJUST select must be moved to MED position.
The factory selection is LO. The adjust selections HI/LO will
regulate airflow supplied for all operational modes, except non-
heat pump heating modes, +10 percent and -10 percent respec-
tively. The adjust selection options are provided to adjust airflow
supplied to meet individual installation needs for such things as
noise, comfort, and humidity removal. (See Fig. 16.)
E.
AC/HP Time Delay
Select desired time delay profile. Four motor operation delay
profiles are provided to customize and enhance system operation.
(See Fig. 16.) The selection options are:
1. The standard 90 sec off delay (factory setting).
2. No delay option used for servicing unit or when a thermo-
stat is utilized to perform delay functions.
