9.5.4. Electric funtions of outdoor

A.1 Control of the compressor, outdoor motor and 4-way valve A.1.1 Outdoor fan motor control

A. When system do not have overheating or over current protection, outdoor fan speed will vary with outdoor ambient temperature, as follows: a. in cooling mode

26℃

22℃

temperature reduce

13℃

super low speed

b. in heating mode (heat pump unit)

16℃

temperature reduce

B.When fan speed changes, if it is from Low speed to High speed, there is no time delay; if it is from High speed to Low speed, there is 45-second delay. C.In cooling mode, in one minute before the compressor begins to run,the outdoor motor will be switched on to run. D.Super low speed control:outdoor motor will be off for 1 minute at the interval of 45 seconds. A.1.2 Compressor control After receiving the “compressor ON” signal sent from indoor unit, the compressor will run. Its running-stop interval is 3 minutes. Being powered on firstly is without 3-minute delay. If the two systems receive the “compressor ON” signal simultaneously,they will start up in turn, and the interval is 20 seconds.

A.1.3 4-way valve control

A. In cooling or dehumidification mode, 4-way valve is not electrified. B. When receiving the “heating” and “compressor ON” signal from indoor unit, 4-way

valve and compressor will start up simultaneously.

C. In 3 minutes after heating is over, it will be shut off 2 minutes and 50 seconds later. In

3-minute standby period, at 2-minute and 50-second clock, it is electrified.

D. Changing from cooling mode to heating mode, 3 minutes later, it is eletrified.

Changing from heating mode to cooling mode , 3 minutes later, it is shut off.

E. In heating mode, when indoor temperature has arrived the set one (sensor is OFF),

4-way valve will be shut off 3 minutes later.

A.1.4 Solenoid valve control

Cooling mode: After the outdoor unit receives the Startup signal from indoor unit, the corresponding solenoid valve will open 10 seconds earlier than compressor startup. Heating mode: After the outdoor unit receives the Startup signal from indoor unit, all the solenoid valve of the corresponding system will open 10 seconds earlier than compressor startup. After the compressor shuts off, the solenoid valvs will close 3 minutes later.

A.1.5 Unloading valve control

When only one indoor unit of one system starts up, the solenoid valve will open. When receiving the overheating signal from indoor unit, solenoid valve will open. If one system only connects one indoor unit (single type), solenoid valve will open. If two indoor units of one system are running, and ourdoor ambient temperature is no more than –2 degree, the solenoid valve will open.

Priority of operation modes:

All indoor units are running in the same mode:

1) Operate as “prior to the earlier entering”, the outdoor will adjust if there is non-matching type and inform of indoor units which is entering later.

2) When there i s non-matching, the indoor unit entering later will act: the indoor buzzer sounds two times, and then the indoor unit is in standby state.

3) Method to eliminate the non-matching type

a) The operation mode of indoor unit entering later changes to the same mode of

A.2 Protection functions

Protection functions of the system can be controlled individually.

A.2.1 Overheating protection

If the units of the two systems are all operating, when the four indoor units all reach the stop-motor point of the overheating protection, outdoor motor can stop. Outdoor motor has

not the control point of High/Med/Low speed. If one indoor unit reaches the stop-compressor point of overheating protection, the corresponding compressor will stop,

but the outdoor motor and the other system will work normally. If the two systems all arrives at the stop-compressor point of overheating protection, the outdoor unit stops; at this time, if one system resumes, the outdoor motor and the system will work normally, the compressor not resuming will stop.

A.2 3-minute protection when compressor starts up

If the compressor stops running, it must 3 minutes later that it can re-start up; if the unit is powered off during operation within 3 minutes, after being powered on, 3 minutes later, the compressor can start up again.

A.2.3 Communication abnormal between indoor and outdoor

Within 4 minutes after outdoor unit is powered on, it cannnot communicate with indoor unit, or in the couse of communication, it cannot communicate with indoor unit for 4 minutes

the one earlier. b) The operation mode of indoor unit entering later changes to FAN mode. c) The operation mode of indoor unit entering earlier stops or changes the mode. d) The operation mode of indoor unit entering later stops.

Chff^j\bZe Abj Chg]blbhg^j

contineously, then the outdoor stops running, and shows failure code. After the communication resumes normal operation and cancel the failure

When all indoor units can not communicate normally, it shows communciation malfunction.

A.2.4 Solenoid valve control with single unit in cooling mode

If indoor unit sends the “start-compressor” signal, the corresponding solenoid valve will open; when shutting off the compressor, the corresponding solenoid valve will close. If the indoor units in one system all send the “stop-compressor” signal, the solenoid valve last receiving signal will close 3 minutes later.

A.2.5 Solenoid valve control with single unit in heating mode

If indoor unit sends the “start-compressor” signal, the corresponding two solenoid valves will open; if there is only one indoor unit, the two valves will open too. A.2.6 When double units of one system are in cooling mode, if the two indoor units send the “start-compressor” signal, the two solenoid valves will open; if one indoor sends “start-compressor” signal, while the other sends “stop-compressor”, then the solenoid valve will open or close respectively. If the two units all send “stop-compressor” signal, the solenoid valve will open for 3 minutes after compressor stops.

A.2.7 When double units of different system are in cooling mode, if the indoor unit sends

the “start-compressor” signal, the corresponding solenoid valves will open; If the unit sends “stop-compressor” signal, the corresponding solenoid valve will open for 3 minutes after compressor stops.

A.2.8 When double units of one system are in heating mode, if any of the two indoor units

sends the “start-compressor” signal, the two solenoid valves will open. After compressor stops, the solenoid valve will close 3 minutes later. A.2.9 When double units of different system are in heating mode, if one indoor unit of one system sends the “start-compressor” signal, the two solenoid valves of this system will open. After compressor stops, the solenoid valve will close 3 minutes later. A.2.10 The treatment for 1 to 3 or 1 to 4 refers to the different combination of the above 1-7 items.

A.2.11 Treatment for anti-freezed function

When the two systems are in operation, if one system enters anti-freezed function, the compressor of this system will stop, while the outdoor motor and the other system will work normally. If the two systems all enter anti-freezed function, outdoor unit will stop operation, at this moment if one system resumes, outdoor motor and the corresponding system will work normally. The compressor of the system which does not resumes will stop.

A.2.12 Treatment for overheating function

The treatment of stop-compressor status is identical to that of anti-freezed status. If one system enters overheating 3, this system will stop, while the outdoor motor and the other system will work normally. If the two systems enter overheating 3, the outdoor will stop; at this moment if one system resumes, outdoor motor and the corresponding system will work normally. If the indoor units of the two systems all enter the overheating 2, outdoor motor will stop. The outdoor will not deal with the status of overheating 1. Note: The overheating point is decided by the indoor unit.
