NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80_F edb temperature of air entering indoor coil.
Below 80_F edb, subtract (corr factor x cfm) from SHG.
Above 80_F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 --- BF) x (edb --- 80).

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80_F edb temperature of air entering indoor coil.
Below 80_F edb, subtract (corr factor x cfm) from SHG.
Above 80_F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 --- BF) x (edb --- 80).

NOTES:
1. Direct interpolation is permissible. Do not extrapolate.
2. The SHG is based on 80_F edb temperature of air entering indoor coil.
Below 80_F edb, subtract (corr factor x cfm) from SHG.
Above 80_F edb, add (corr factor x cfm) to SHG.
Correction Factor = 1.10 x (1 --- BF) x (edb --- 80).

CONTROLS
Sequence of Operation
40QAC/QAQ
Automatic air sweep
All under--ceiling units are equipped with an automatic air sweep
feature, which automatically directs the airflow louvers up and
down to provide optimum room air circulation. If the automatic
sweep feature is not desired, temporarily start the automatic sweep
using the toggle switch on the unit. When the louvers are in the
desired position, turn the automatic sweep off to hold them in that
position.
Operating sequence
Ceiling--suspended fan coil units have a relay board which controls
system operation in response to the room thermostat. The user may
manually select any one of 3 fan speeds for unit operation. Ceiling
suspended systems may be equipped with an accessory power
ventilation kit and/or condensate pump.
Duct--free splits thermostat operation
Operating mode memory
After the system is turned off or after a power failure the system
remains in the last operating mode selected. When the system is
turned back on, or when power is automatically restored, operation
continues in the same operating mode as when the system shut
down.
Automatic operation (auto) mode
If Auto. mode is selected, the system automatically switches over
the operating mode from heating to cooling, or from cooling to
heating depending on the selected temperature. Auto. mode also
controls fan speed if not manually overridden.
Fan operation
Fan speed can be selected by pressing the fan button (either high,
medium, or low speed). The fan is capable of operation when unit
mode is set on cooling, heating, or auto. mode. When the fan is
operating in medium or high speed and the unit is equipped with
the power ventilation kit, the ventilation fan will operate to provide
fresh air.
Increased demand for cooling
(heat pump systems)
1. When the room thermostat senses a demand for cooling, the
fan coil relay board is energized and the indoor fan will start
in the selected speed (if it is not already operating).
2. The reversing valve is energized at all times when in
cooling mode.
3. The internal condensate pump (if so equipped) runs
whenever the reversing valve is energized. The internal
condensate pump (if so equipped) runs whenever there is a
demand for cooling.
4. As long as the condensate float switch and freeze protection
thermostat are closed, the cooling relays in the fan coil unit
will close. This energizes the compressor and outdoor fan in
the outdoor unit. The compressor will continue to operate
until the room thermostat is satisfied.
5. When the cooling demand is satisfied, the compressor and
outdoor fan will stop. If the system is in Auto. mode, the
indoor fan will stop with the compressor. If the unit has the
accessory ventilation kit, the ventilation fan will operate
whenever the indoor fan is set for medium or high speed.
Increased demand for heating
(heat pump systems)
1. When the room thermostat senses a demand for heating, the
fan coil relay board is energized .
2. The indoor fan will start in the selected speed (if it is not
already operating). The reversing valve will not be
energized. The internal condensate pump (if supplied) and
freeze protection thermostat are not operated during heating
operation.
3. The control relay closes, and the compressor and outdoor
fan are energized through the defrost and the defrost timer
runs.
4. Once every 90 minutes (the factory default setting) of the
compressor run time, the DFB (defrost board) logic checks
the defrost thermostat (DFT). If the DFT is open, the unit
continues in heating operation. If the DFT is closed, the
DFB switches the unit to defrost mode. The timing on the
DFB may be set at either 30, 50 or 90 minutes.
Defrost
The DFB energizes the RVS (reversing valve solenoid), and the
reversing valve switches to the cooling position. The relay on the
DFB opens and the outdoor fan stops. The contact on the DFB is
also energized, which in turn energizes the defrost relay on the fan
coil relay board, turns off the electric heater and stops the indoor
fan. The DFB logic checks the 10--minute defrost timer and the
DFT. If the DFT opens in less than 10 minutes, the defrost board
switches the unit back to normal heating operation. If the DFT
remains closed the DFB switches the unit back to heating operation
after 10 minutes. When the DFB changes back to heating mode,
the RVR (reversing valve relay) is deenergized and the reversing
valve switches back to heating operation. Both the outdoor and
indoor fans come back on, and if necessary, the electric heater also
turns on.
System safeties
The system is equipped with the following safety devices to protect
system components:
S
Indoor coil freeze protection thermostat (cooling cycle
only). If a coil temperature of 28_F or lower is sensed,
the compressor and outdoor fan will be shut down until
the coil temperature exceeds 28_F. The indoor fan will
continue to run.
Condensate float switch (units equipped with accessory
condensate pump, cooling cycle only).
If the level of condensate in the drain pan rises too high the
condensate float switch will turn off the compressor and outdoor
fan until the condensate level returns to normal. The indoor fan
will continue to run.
Special operation heat mode
Outdoor cooling units can be matched with heat pump
ceiling--suspended fan coil units to provide supplemental electric
heat. All other operation is the same as a cooling only system,
except these units have the following heating capability:
S
22
S
When the room thermostat initiates a call for heating, the
electric heater is turned on.
S
The indoor unit fan will start at the same time if it was
not already operating.
S
When the heating requirement is satisfied, the room
thermostat will open and the heater will turn off.
