of outdoor thermostat (field installed option), contacts close to complete
circuit and bring on second bank of supplemental electric heat.
When thermostat is satisfied, its contacts open, decnergizing contactor
and relay. All heaters and motors should stop.
Quiet Shift-2
Quiet Shift-2 is a field selectable defrost mode (factory set to OFF),
which will reduce the occasional noise that could be heard at the start of
defrost cycle and restarting of heating cycle. It is selected by placing DIP
switch 3 on defmst board in the ON position.
When Quiet Shift-2 switch is placed in ON position, and defrost is
initiated, the following sequence of operation will occur.
— The compressor will be de --energized for approximately I minute,
then the reversing valve will be energized A few seconds later, the
compressor will be re -energized and the normal defrost cycle starts.
Once defrost termination conditions have been met, the following
sequence will occur:
— The compressor will be de -energized for approximately 1 minute,
then the reversing valve will be de -energized. A few seconds later,
the compressor will be re -energized and the normal heating cycle
starts.
Defrost
The defrost control is a timeltemperature control which includes a field
selectable time period between defrost cycles (30, 60, 90, or 120). The
time period is selected using DIP switches located on the board. The
setting is initial period only then varies with defrost length.
The defrost thermostat senses coil temperature throughout the heating
cycle. When the coil temperature reaches the defrost thermostat setting
O
El
of approximately 32°F (0°C), it will close, which energizes the DFT
terminal and begins the defrost timing sequence. The timer mas only
when the defrost thermostat is closed and the contactor is energized.
Defrost mode is identical to cuofing mode except that outdoor fan motor
stops and second -stage heat is turned on to continue warming
conditioned spaces.
Defrost Speedup
Quiet Shili Models
To initiate a forced defrost, speedup pins (]I) most be shorted with a flat
head screwdriver for 5 seconds and RELEASED. If the defrost
thermostat is open, a short defrost cycle will be observed (actual length
depends on Quiet Shift-2 switch position). When Quiet Shift-2 is off,
only a short 30 second defrost cycle is observed. With Quiet Shift-2 ON,
the speedup sequence is approximately 3 minutes; 1 minute compressor
off period followed by 30 seconds of defrost with compressor operation.
When returning to heating mode, the compressor will turn off for an
additional minute.
Ifthe defrost thermostat is closed, a complete defrost cycle is initiated. If
the Quiet Shift-2 switch is turned on, the compressor will be turned off
for two I -minute intervals as explained previously.
If Quiet Shift 2 is enabled, the variable defrost intervals will be disabled
to provide options where using a specific setting is desired. In this case
the 30, 60, 90, or 120 setting will not change unless the dipswitch is
changed, and power is cycled.
NOTE: Forcing a defrost will reset the defrost interval to the DIP switch
setting before resruing variable length intervals based on defrost cycle
lengths.

FJ4: Installation Instructions
Introduction
These R-410A Fan Coils are designed for installation flexibility. The
units leave the factory compliant with low leak requirements of less than
2% cabinet leakage rate at 0.5 inches W.C. and 1.4% cabinet leakage rate
at 0.5 inches W.C. when tested in accordance with ASHRAE 193
standard.
All these fan coils use a multi -tap ECM motor for efficiency. The units
have been designed for upflow, downflow (kit required), and horizontal
orientations, including manufactured and mobile home applications.
These units require a field supplied air filter, and are designed
specifically for R-410A refrigerant air conditioners and heat pumps as
shipped. These units are available for systems of 18,000 through 60,000
BTUh nominal cooling capacity. Factory- authorized, field - installed
electric heater packages are available in sizes 5 through 30kW. See
Product Data literature for all available accessory kits.
Heater Packages
NOTE: Some heater sizes may require the removal of two screws which
connect the blower housing to the fan deck (removal will not impact
performance). See (Care and Maintenance on pl1) and Fig. 22.
This unit may or may not be equipped with an electric heater package.
For units not equipped with factory -installed heat, a factory -approved,
field -installed, UL listed heater package is available from your
equipment supplier. See unit rating plate for a list of factory -approved
heaters. Heaters that are not factory approved could cause damage which
would not be covered under the equipment warranty. If fan coil contains
