Introduction to System
Introduction
Single Zone Ductless Split System Heat Pumps feature a wall
mounted indoor fan/evaporator unit that receives refrigerant
from an inverter driven variable speed outdoor condensing
unit. System operation is controlled by a hand-held remote.
The outdoor unit features a variable speed rotary
compressor, EEV metering device and DC fan motor. These
systems use R410A refrigerant and PVE oil. The outdoor units
are 208/230 volt rated systems for 18k/24k and 115 volt for
9k /12k. They are factory charged for up to 25 feet of
refrigerant piping.
The indoor section is wall mounted.
The unit has a room temperature sensor and a coil
temperature sensor that maintain room comfort.
 The systems are designed to operate in temperature
ranges of 60°F to 86°F in cooling mode and 60°F to 86°F in
heat mode.

indoor and outdoor units. Tubing must be sized per the
specifications of the unit being installed and must be
insulated. Any adjustments to the original factory charge
must be by weigh-in ONLY.
 The condensate system is a gravity type. A field installed
condensate pump may be added to the system. Always
follow the manufacturer’s installation instructions when
installing a condensate pump.
. Clearances to obstructions for both indoor and outdoor
units mustbe maintained according to the installation
manual.
Fundamental Theory Of Operation
The indoor unit will sense room temperature at the point
where the wall unit is installed. The indoor fan will run
continuously when placed in heating or cooling mode
operation and will not cycle on and off with the outdoor
unit. If it did, room temperature could not be sensed or
maintained.
The inverter compressor system in the outdoor unit will vary
the refrigerant flow and indoor air volume levels to match
the cooling requirement inside the conditioned space. If an
abnormal condition is detected by the system’s sensors, the
system has the ability to take reactive measures.
The amount of refrigerant flow and associated capacity
generated by the system will be determined by how fast the
variable speed rotary compressor is pumping.Thecompressor
operating speed requirement is determined bythe difference
between the conditioned space temperatureversus the set
point established by the remote control.
If a large amount of capacity is needed, the compressor will
operate at a high speed. As the need for capacity
reduces and the temperature of the room nears set point,
the compressor will slow down. When set point has been
reached, the compressor will shut off but the indoor fan
will continue to operate. Once a difference in temperature
is sensed between remote control set point temperature
and room temperature, the compressor will restart at a new
calculated speed.
If a system sensor determines there is a need to adjust
the frequency signal to prevent a system malfunction,
the compressor frequency may be over ridden and a new
frequency established. It should be noted that the frequency
signal level that is sent to the compressor cannot be
determined by a servicing technician.
In this manual, system components, operation, sensor
functions and diagnostic procedures will be explained in
greater detail.
Specifications for Proper Operation should be follow

Outdoor Fan Motor
The 18K and 24K units are 208/230 volt single phase. The
9K and 12K units are 120 volt. All models use terminals 1
and 2 as incoming power wiring. Number 3 is the
communication terminal and the 4th terminal is the ground
connection. Be sure to match this wiring with the indoor
unit terminals.
External accessories such as a condensate overflow switch
should break the number 2 (line) terminal.
The indoor unit is powered from the same source as the
outdoor section and is connected by using 14/4 AWG
stranded wire.
There should be no splices in the wiring between the indoor
and outdoor unit number 3 terminal. Splices may create a
loss of communication and generate an E7 error code.
The Reactor is an inductive filter that will aid in correction of
electrical power factor influence of inverter capacitance. It is
unlikely to ever have an electrical failure of this component.
The Reactor is electrically connected to the Module Board on
terminal connections CN-6 and CN-7.
The compressor is a three phase DC inverter driven rotary
type. The compressor is capable of variable speed operation.
The compressor operating frequency will be determined by
the temperature difference between set point and room or
outdoor air temperature.
The compressor is electrically connected to the Module
Board on terminal connections CN-2, CN-3 and CN-4.
The compressor has an internal temperature overload that
will open if the compressor becomes too hot. Additional
protection of the compressor will be provided by the
Compressor Discharge Temperature Sensor and Suction
Line Temperature Sensor.
The outdoor fan motor is a variable speed DC motor. The
required motor speed is calculated by the Main Control
Board. The motor is electrically connected to the Main
Control Board via PLUG CN-9.
In COOL MODE operation, the motor will slow down as
outdoor air temperature falls. In HEAT MODE operation, the
motor will increase speed as the outdoor air temperature
falls.

Discharge Temperature Sensor
Defrost Temperature Sensor
Outdoor Ambient Temperature Sensor
Suction Line Temperature Sensor
The Discharge Temperature Sensor is a negative coefficient
thermistor that senses the temperature of the compressor
hot gas. The Main Control Board monitors the temperature of
the compressor hot gas and will make inverter speed changes
in response to input from this device.
This sensor connects to the Main Control Board at PLUG CN-
20.
The Defrost Temperature Sensor is a negative coefficient
thermistor that will change resistance in response to outdoor
coil temperature changes. The Main Control Board monitors
the temperature of the outdoor coil to determine when a
defrost cycle is necessary.The sensor alsomonitors outdoor
coil temperature during defrost cycles todetermine termination
conditions.
This sensor connects to the Main Control Board at PLUG CN-
20.
The Outdoor Ambient Temperature Sensor is a negative
coefficient thermistor that will change resistance in response
to outdoor air temperature changes. The Main Control Board
monitors the temperature of the outdoor air to determine
outdoor fan speed requirements and compressor speed. The
sensor also plays a role in calculation of required defrost
conditions.
This sensor connects to the Main Control Board at PLUG CN-
20.
The Suction Line Temperature Sensor is a negative
coefficient thermistor that senses the temperature of
the suction line. The Main Control Board monitors the
temperature of the suction line to determine EEV orifice size
in an attempt to maintain proper operating superheat.
This sensor connects to the Main Control Board at PLUG CN-
18.

4-Way Valve
Electronic Expansion Valve
Accumulator
Refrigerant Filters
The 4-Way Valve redirects the flow of refrigerant in the piping
circuit to allow the system to reverse the functions of the indoor
and outdoor coils. When de-energized in COOL MODE, the
valve will direct the refrigerant hot gas to the outdoor coil.
When energized in HEAT MODE, the valve will direct the hot
gas to the indoor coil.
The direction of flow is changed by an electrical solenoid that
moves an internal slide mechanism when energized.
The 4-Way Valve is electrically connected to the Main Control
Board at PLUG CN-10.
The metering device is an electronic expansion valve .
The valve consists of an electrical operator and a valve
body with internal variable size orifice. When operating,
the Main Control Board will send pulses of voltage to the
electrical operator. The operator will then magnetically move
the position of the metering orifice pin to vary the flow of
refrigerant through the valve.
The metering device position is determined by input from
a Suction Line Temperature Sensor located in the outdoor
unit. The EEV will change the internal orifice size to maintain a
superheat level of around 10°F.
During COOL MODE operation, the valve meters low
pressure refrigerant to the indoor coil. During HEAT MODE
operation, the valve meters low pressure refrigerant to the
outdoor coil.
The Accumulator is located in the suction line circuit at the
entrance to the compressor. The accumulator helps prevent
liquid refrigerant from entering the compressor .
The system has debris-catching filters that protect internal
system components from contaminants in the refrigerant.
The filter is a permanent part that is not typically replaced.

increases in room air temperature. The sensor is located on a
clip mounted to the surface of the indoor coil.
The sensor connects to the control board at Plug CN-6.
The indoor display has an infrared communication circuit that
receives operating commands from the remote control. This
display will indicate operating modes, error codes, indoor air
temperature, timer status and power status. The Piping Temperature Sensor is a negative coefficient
thermistor that will decrease in resistance with increases in
coil temperature. The sensor is located in a socket soldered
to the surface of the indoor coil.
This sensor will monitor the temperature of the indoor coil
in both cooling and heating modes of operation. Should
abnormally cold or hot coil temperature be detected by this
sensor, the system will take steps to correct the condition or
report an error code.
The sensor connects to the control board at Plug CN-6.

The Stepper Motor moves the louver up and down. The
motor is connected to the Indoor Control Board at Plug
CN-11. Louver left and right funcution is not available for
Tempo series
The Indoor Fan Motor is a variable speed DC motor. The
motor will vary speed with the speed of the compressor.
The speed can also be changed at the remote control
or automatically adjusted using the AUTO fan mode. When
in AUTO fan mode, the speed of the fan is calculated using
the indoor set temperature and the indoor room ambient
temperature. (Outdoor air temperature in heat mode.)
The Fan Motor is connected to the indoor control board via
PLUG CN-9.
If the remote control is non-functional, the Emergency
Button can be accessed by swinging open the front of the wall
unit. The button is located on the right side.
Pushing this button will activate AUTO MODE operation.
AUTO MODE activated with this button will maintain 75°F.
The system will stay in this mode until commands are
received by the indoor unit communication circuit via the
remote control.There is a discrepancy here. Some literature
indicates auto mode, others say cooling mode.
