3 PRODUCT FEATURES
3.1 General introduction
Gree Photovoltaic Direct-driven Inverter VRF adopts inverter compressor technology. By changing the displacement of compressor,
3.1.1 Features
3.1.2 Features of Duct Type Indoor Unit
◆Flexible setting and even air supply
◆Convenient installation
Can be installed in the ceiling
◆With fresh air function to improve indoor air quality
Fresh air duct can be connected
◆Wide adjusting range of static pressure and air volume
Static pressure and air volume can be set according to actual requirements
3.1.3 Features of Wall Mounted Type Indoor Unit
Photovoltaic Direct-driven VRF
stepless capacity regulation within rangeof 15%~100% can be realized. Various product lineups are provided with capacity range from
36000Btu/h to 48000Btu/h, which can be widely used in residential, commercial and working area and especially applicable to places
with big load change. Gree residential air conditioner is absolutely your best choice.
(1)
Gree Photovoltaic Direct-driven Inverter VRF System adopts DC motor to realize complete direct current and upgrade the energy
(2) New generation CAN bus communication
Due to the latest communication method—CAN Bus Communication, system’s anti-interference capability is stronger and the control
on indoor units is more accurate, with higher reliability. Specialized shield wire is no more needed and ordinary communication wire can be
.
(3) Long connection pipe
The maximum length of connection pipe is 300m (in total) and the farthest connection pipe between indoor and outdoor units can be
120m’s long, which has extended the installation condition and reduced the limit of installation distance.
(4) Wide operation range
Units can operate reliably in a wide temperature range (cooling:10~54
oC, heating: -30~27oC).
(5) Fine sound quality
Through a series of optimized measures, system has reduced the throttle noise and oil return noise of indoor units, gas bypass noise,
etc. so that units are more comfortable regarding sound quality.
(6) Reliable low-temperature running
The controller uses the low temperature elements, which can run reliably at -35
(7) Complete protection
Units are equipped with a series of protection to accurately identify errors and protect the units, which has ensured reliable and safe
operation.
efficiency. SEER is up to 18 and HSPF is up to 11.
℃ . The compressor can normally start up below -35 ℃ .

PRODUCT
◆Filter can be cleaned
◆Quiet design
◆One IDU with several wired controller and several IDUs with one wired controller
One IDU can be connected with several wired controllers in order to control one IDU from different location; meanwhile, several IDUs
can be connected with one wired controller in order to achieve centralized control of 16 IDUs in maximum.
◆Wide air supply range
The air supply range is wide, so that the wind can be delivered to each corner of the room naturally and evenly.
◆Super cooling and heating function
Intelligent temperature control technology is adopted with super cooling and heating function, so that the room temperature can reach
set temperature rapidly.
◆I-feel function
When I-feel function is activated, the unit can detect the temperature around the user and adjust the temperature, so that the comfort of
user is improved. (Remote controller shall be equipped)
◆Panel is removable
The panel of indoor unit can be removed easily for convenient maintenance.
◆CAN bus communication technology and auto addressing
The response of the system is quicker with more reliable communication; auto addressing, non-polar communication and free wiring
are available.
◆Multiple protections
Anti-freezing protection, temperature sensor malfunction protection, fan motor overload protection, auxiliary electric heating overheat
protection (This function is not included in pure heat pump unit).

5.1 Instruction of Product Capacity Correction
Nominal cooling capacity and nominal heating capacity are tested under given conditions:
(1) Rated cooling or heating condition．
(2) No height difference between indoor unit and outdoor unit.
(3) Short connection pipe.
If the three conditions above have changed, the cooling and heating capacity will change correspondingly and correction is needed.

In cooling, the low-temperature and low-pressure refrigerant gas from each indoor heat exchanger will be merged and inhaled by the
compressor and then become high-temperature and high-pressure gas, which will later be discharged into outdoor heat exchangers. By
with indoor air, refrigerant wil become low-temperature and low-pressure gas again and repeat the circulation so as to realize the cooling
effect. In heating, 4-way valve will be energized to make refrigerant circulate in a reverse direction of cooling. Refrigerant will release heat in
indoor heat exchangers (electric heating elements will also work under certain circumstance and release heat) and absorb heat in outdoor
heat exchangers circularly so as to realize the heating effect.

1 Units’ Control
1.1 Schematic diagram of units’ control
Air conditioning units can be divided into indoor unit and outdoor unit. A maximum of 16 sets of indoor units
can be connected to an outdoor unit. 2-core (3-core pin header) communication cable is used for the connection
between indoor unit and outdoor unit. Indoor unit is connected to display board via 4-core communication cable. In
engineering installation, address dial-up of the display board and the mainboard of indoor unit shall be dialed. The
address dial-up of the mainboard of indoor unit must be identical with that of the display board of the same indoor
unit. Address dial-up of different indoor unit must vary. Multi VRF indoor unit is applicable to all digital or inverter
outdoor units.
Controller of outdoor unit falls into two categories in terms of its function, i.e. main control system and
inverter drive control system

Above is a simple installation method of wired controller. Please pay attention to the following:
1) Before installation, disconnect power of the indoor unit. Do not operate when power is connected.
2) 2-core twisted pair cable from the installation hole on the wall and lead it through the hole on the back plate of wired controller.
3) Place the wired controller on wall and secure its back plate on wall with screw M4X25.
4) Connect the 2-core twisted pair cable to terminal H1 and terminal H2. Tighten up the screws.
5) Stick the cable in the slot that is left of the terminals and buckle the wired controller’s panel with its back plate.
point 5, strip some of the sheath of the communication cable to meet the installation requirement.
