QUICK SETUP
Simple startup using communicating thermostat
1. Turn off the breaker of the outdoor unit and the furnace
2. Connect COND1 and COND2 on the interface board to N(1) and 2 at the outdoor unit (See Figure 13 to Figure 15)
3. Connect the RJ-11 wire between the interface and the furnace control board (See Figure 13 to Figure 15)
4. Turn the outdoor unit “ON”
5. Turn the furnace “ON”
Make sure the unit is working properly
1. The Green LED on the interface board should be blinking once every two seconds
2. The Orange LED on the interface board should be blinking once every two seconds
3. The communicating thermostat will display “Heat_Pump_Found”
4. Set the thermostat to “COOL” mode and adjust the set point to a lower value than the actual room temperature
5. The furnace and the outdoor unit should start within 5 minutes
Modulating furnace
1. Connect the RJ-11 wire between the interface and the furnace control board
2. Connect the two wire coming from the outdoor unit
In this configuration, the interface board will gather information from both the outdoor unit and the furnace in order to adjust the fan
speed to the capacity of the outdoor unit
Legacy connection
1. Connect all the thermostat control wires to the interface board and the air handler control board (See Figure 27)
2. Make sure to connect the auxiliary heat outputs (W1 out and W2 out to the W1 and W2 inputs of the furnace)
3. Connect 1 and 2 on the interface board to N(1) and 2 at the outdoor unit (See Figure 27)
4. Set the dipswitches to the desired balance point (See Table 2)

1- SAFETY PRECAUTIONS
Installing, starting up, and servicing air conditioner can be hazardous due
to system pressure, electrical components, and equipment location, etc.
Only trained, qualified installers and service personnel are allowed to
install, start-up, and service this equipment. Untrained personnel can
perform basic maintenance functions such as cleaning coils. All other
operations should be performed by trained service personnel.
When handling the equipment, observe precautions in the manual and
on tags, stickers on the equipment. Follow all safety codes. Wear safety
glasses and work with gloves. Keep quenching cloth and fire
extinguisher nearby when brazing.
Read the instruction thoroughly and follow all warnings or cautions in
literature and attached to the unit. Always follow building codes and
current edition of national as well as local electrical codes.
Recognize the following safety information:
Warning: Incorrect handling could result in personal
injury or death
Caution: Incorrect handling may result in minor injury, or damage
to product or property
WARNING
1.1- WARNING
All electric work must be performed by a licensed technician according
to local regulations and the instructions given in this manual
⇒Before installing, modifying, or servicing system, main electrical
disconnect switch must be in the OFF position. There may be
more than 1 disconnect switch. Lock out and tag switch with a
suitable warning label;
⇒Never supply power to the unit unless all wiring and tubing are
completed, reconnected and checked;
⇒This system adopts dangerous electrical voltage. Incorrect
connection or inadequate grounding can cause personal injury
or death. Stick to the wiring diagram and all the instruction when
wiring;
⇒Have the unit adequately grounded in accordance with the local
electric codes;
⇒Have all wiring connected tightly. Loose connection may lead to
overheating and a possible fire hazard.
All installation or repair work shall be performed by your dealer or a
specialized subcontractor as there is the risk of fire, electric shock,
explosion or injury.
⇒Make sure the outdoor unit is installed on a stable, level surface
with no accumulation of snow, leaves, or trash beside;
⇒Avoid contact between refrigerant and fire as it generates
poisonous gas;
⇒Apply specified refrigerant only. Never have it mixed with any
other refrigerant. Never have air remain in the refrigerant lines
as it may lead to rupture and other hazards;
⇒Make sure no refrigerant gas is leaking out when installation is
completed;
⇒Should there be refrigerant leakage, the density of refrigerant in
the air shall in no way exceed its limited value, or it may lead to
explosion;
⇒Keep your fingers and clothing away from any moving parts;
⇒Clear the site after installation. Make sure no foreign objects are
left in the unit;
⇒Always ensure effective grounding for the unit.
CAUTION
1.2- CAUTION
⇒Never install the unit in a place where a combustible gas might
leak, or it may lead to fire or explosion;
⇒Provide a ground fault interrupter (GFI) when it is installed in a
watery place;
⇒Never wash the unit with water
⇒Handle unit transportation with care. The unit should not be
carried by only one person if it is more than 20 kg;
⇒Never touch the heat exchanger fins with bare hands;
⇒Never touch the compressor or refrigerant piping without
wearing glove;
⇒Make sure that the air handler filter is clean;
⇒Should any emergency occur, stop the unit and disconnect the
power immediately;
⇒Properly insulate ALL refrigerant tubing from outdoor units to the
interior cooling coil to prevent water dripping.
