F.
CONTINUOUS FAN - Select desired fan speed when thermostat is set on continuous fan
NOTE:
If installed with a 2-speed outdoor unit, do not select HI speed continuous fan. If HI is selected, low speed compression will also run HI
speed possibly resulting in insufficient dehumidification.
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. 17, F as indicated.)
G.
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.
H.
Basic Fan Coil Configuration
The following basic configuration of the fan coil will provide ARI rated performance of the heat pump:
1. AUX HEAT KW/CFM - Select the heater range for the size electric heater installed.
2. AC/HP SIZE - Select system size installed.
3. SYSTEM TYPE - Select system type HP-EFF.
4. AC/HP CFM ADJUST - Select NOM.
5. ON/OFF DELAY - Select 0/90 profile.
6. CONTINUOUS FAN - Select desired fan speed when thermostat is set to continuous fan.

COMFORT OPTIONS - WARMER HEATING AND SUPER DEHUMIDIFY (See Fig. 21 for Quick Reference Guide)
The FV4B Fan Coil provides better than average humidity control and heated air temperature. This configuration will improve the comfort
provided by the heat pump system if more humidity removal or if warmer heating air is desired. While providing this improved comfort, the heat
pump system will operate efficiently, but not at the published HSPF or ARI SEER efficiency.
The following fan coil configuration is recommended for maximum heating and cooling/dehumidifying comfort: (See Fig. 17.)
1. AUX HEAT KW/CFM - Select narrowest heater range to match size of electric heater installed (skip this step if no heater is installed).
2. AC/HP SIZE - Select system size installed.
