6 ELECTRICAL CONTROL FUNCTIONS 6.1 Indoor unit NO. Setting method 6.1.1 In order to control all indoor units of H-MRV systems, the indoor units number should be set after installation work. We have two ways to set indoor unit number according to indoor unit type. Normally the infrared remote control types use special remote controller to do indoor unit number setting, the wired types use dialing switch (on indoor unit PCB) to do indoor unit number setting. The details is as follows : No.
6.1.2 Function of special remote controller (Adress setting) 1. Read function symbol Press “read” button , “1” flashes 1 time 2 2. Signal emitting symbol when “2” flashes ,it shows that remote controller is giving signal to indoor unit. press “8”button to select indoor unit number (1,2,3,4,5or6), then “3” flashes continuously ,press “7” to set indoor unit number 4. Button locked symbol When “9” is on the state of “ ↗”,press “10”button , “4” appears to show other buttons are locked .
6.1.3 Number setting dialing switch using method(wired remoted control type) The dialing switch is on indoor unit PCB. The indoor unit number setting method is as follows: OFF stand for NO.1 indoor unit Digit 1 0 1 0 1 0 1 Digit 2 0 0 1 1 0 0 Digit 3 0 0 0 0 1 1 stand for NO.2 indoor unit Digit 4 Not used Not used Not used Not used Not used Not used Unit number stand for 1 2 3 4 5 6 7.1.4 Indoor unit NO. lock switch (for model AU422FIAHA,AU422FIAIA, AU422F I B H A) We have “indoor unit NO.

6.3 Defrost operation Flow Chart 1. The compressor operates heating over 25 minutes, after meeting the defrosting condition, it is permitted to enter defrosting. Defrosting process is unit-stop defrosting mode. Determining condition of defrosting is as follows: Unit-stop defrosting: (1) When outdoor ambient temperature is less than 2 , (outdoor ambient temperaturedefrosting sensor) is more than 9 , and keeping over 2 minutes, enter unit-stop defrosting.
2. Compressor control The compressor will start at 10Hz and running between 30Hz to 120Hz. In operation the compressor running frequency is determined by three elements : the number of indoor units in operation , the temperature difference of each indoor units between setting temperature and room temperature , the size of each indoor unit. 3.
7 DIAGNOSTIC INFORMATION (TROUBLE SHOOTING) 7.1 Fault Codes In order to make repair and maintenance convenient, we set “Automatic troubleshooting” function in indoor unit and centralized controller. If any abnormal phenomenon occurs in operation, you can determine the trouble part and condition from the indicator light in indoor unit or the trouble code on the centralized controller.
Indoor unit malfunction display code Indoor unit malfunction Float switch or water motor abnormal Outdoor unit abnormal Setting running mode is different with outdoor running mode Liquid temperature sensor is abnormal Gas temperature sensor is abnormal The communication between indoor 846 chip and communication chip is abnormal The communication with electronic expansion box is abnormal The communication between the wire remote controller and indoor unit control board is abnormal The communication between i

7.2 Troubleshooting (1) Indoor unit trouble indication: timer indicator flashes (once, twice, 3 times, 7 times) Abnormal reasons: Heat sensitive resister is short circuit or open circuit The treatment to sensor output part in PC board is improper, such as poor contact of package part, the electrolytic capacitor for filtering is failed, etc. Treatment: Remove the heat sensitive resister, test and measure its numerical value.
Treatment: use the DC voltage grade of multimeter to test the plastic sealed motor to find if there is any feedback signal, determine if the plastic sealed motor is abnormal. If normal, change the indoor unit PC board. (6) Indoor unit trouble indication: Timer indicator flashes (12 times) Abnormal reason: Indoor unit PC board is improper Treatment: change the improper indoor unit PC board.
Refrigerant leaks Discharging air temperature heat sensitive resistor is improper Electronic expansion valve or 2-way valve is closed Treatment: check if there is leakage part, test system pressure in rated operation state to determine if there is leakage? Check the state of electronic expansion valve and 2-way valve. Test and measure the numerical value of discharging air temperature heat sensitive resister. 7.3 Example of repair (1) Phenomenon: after changing the PC board of outdoor unit, do not reset.

l l l l l l l l l l l work is not met with the requirements, overturn of the unit will occur resulting in accidents. The wiring work shall be done by a qualified person and referred to the “technical standard of electric equipment”, “indoor wiring regulation” and what the manual specified. Do use special circuit. If the capacity of the circuit is not enough or bad work, electric shock, fire and other accidents will happen.
8.8 Special Work and Main Points in Installation Warning l l During installation, if refrigerant l leakage occurs, take ventilation measurement immediately. l As soon as the leaked refrigerant gas meets fire, poisonous gas will generate. After finishing installation, confirm the refrigerant gas does not leak. If the refrigerant gas leaks in the room, once it meets heater, burner and gas stove etc. fire source, the poisonous gas will generate. A.
(4) Pipe connection of the outdoor unit Referring to the installation diagram in page 4, connect the indoor unit, outdoor unit, branch pipe and electronic expansion valve together by using the pipe connection method and welding method. (5) Test of airtight quality After connection of the refrigerant pipes, carry out airtight quality test.
8.9 Test of leakage after wiring work is finished After connection of the refrigerant pipes, carry out leakage test. In this test, pressurize to the pipes as shown in the below figure by using nitrogen tank. Close the valves of the gas side and liquid side totally. The nitrogen may enter the cycle system of the outdoor unit, so that, before pressurizing, the valve rods must be fastened. (Both the gas side and liquid side).
c. Vacuumize 2~3 hours according to the length of the pipe. When vacuuming, confirm the gas side and liquid side of the 2-way valve and 3-way valve shall be in full close state. d. When it is not lower than 200Pa after 2 hours or more vacuuming, vacuums for another 1 hour. If after more than 3 hours vacuuming it is still not lower than 200Pa, the leak part shall be found. e.
8.11 Refrigerant MRV central air conditioner uses refrigerant “R22”. This refrigerant itself is innocuous, non-combustible safety refrigerant. But then, when arranging the air conditioner equipment, it is necessary to take some steps to take precautions against in case of the indoors refrigerant leakage. Such as, the room size shall be taken into account to avoid making the concentration of the refrigerant not exceed the concentration limit and other relevant steps.
8.12 Electric wiring Note: l l l l l l l The air conditioner must use special circuit (over 40A), and wiring by the qualified electrician according to the wiring rules specified in national standard. The grounding wire and the neutral wire shall be strictly separated. Connect the neutral wire with grounding wire is incorrect. The electric leakage breaker must be installed. All the electric wire must be copper wire.
Wiring method 1. Wiring method of orbicular terminals For the connection wire with orbicular terminals, its wiring method is as shown in the right figure: remove the connecting screw, put the screw through the ring on the end of the wire, then connect to the terminal block and fasten screw. 2.
2. Do not connect the power line with different dimensions to the same grounding wire end. Improper contact will affect protection. 3. Keep a proper distance between the communication wire and the power line. Otherwise, abnormal communication will occur because of disturbance. 4. Do not connect the power line to the connecting end of communication wire. Incorrect connection will cause damage of connected unit. 5.The communication wire must be shielding wire. Wiring example diagram: 8.
