11.5 Run Mode
Run mode is the default operation mode of the system. This is the standard operation mode that is active in field application (at customer site). System can go from run mode to other operation modes through keyboard or serial ports.
11.5.1 Mode Setting
Mode defines the ODU operation mode. There are three possible operation modes:
1. STBY – standby mode
2. COOL - the unit operating at cooling cycle
3. HEAT - the unit operating at heat pump cycle
The ODU define the system operation mode according to three methods set by the display key board:
1. First request priority
The first IDU which requests different mode than STBY mode will set the new operation mode. The mode will change once all the units exit the current operation mode.
2. Priority unit
If an IDU is defined as a priority unit, the operational mode will be defined according to that unit request, unless the unit is at STBY mode. In case priority unit is SB the mode will be set acceding to first request priority.
3. Forced operation mode
If forced mode is enabled than the ODU mode will be forced according to the Forced mode input: Open COOL Short HEAT The ODU will go to SB if all the IDU are at SB or at different modes.
4. SB Input
The ODU will change mode between COOL/HEAT and Idle according to the STBY dry contact input as follows:

Deicing interval time when compressor is first started in heat mode, is 10 minutes if OCT < -2, and is 40 minutes in other cases. Deicing interval time is changed (increased/ decreased in 10 minutes steps) as a function of deicing time. If deicing time is shorter then former deicing time, the deicing interval time will be increased. If deicing time is longer then former deicing time, the deicing interval time will be decreased.

11.6 Installation Test Mode
11.6.1 Test Objectives
Find tube-communication wires mismatch.  Instruct the technician to match the tubes to the communication wires. Find EEV or tubing problems.
11.6.2 Test Concept
The unit will open each EEV separately in cooling mode. Detect a temperature drop on the indoor unit. Based on the temperature drop, the system can match the tube to the indoor unit.
11.6.3 Test Rules
Before starting the installation/technician test, make sure for the following:
No indoor communication channel is connected to non existing tube channel.1.
The number of the connected/installed indoor unit is set properly.2.
All the EEVs are connected properly to the right EEV channels.3.
No mix between the indoor unit’s tubes, each indoor unit must have its own tubes connected 4.
properly to the outdoor unit.
If the rules above are not respected, the test results will make no sense.

12.4 Procedures for checking Main Parts
12.4.1 Checking Mains Voltage
Confirm that the Mains voltage is between 198 and 264 VAC. If Mains voltage is out of this range, abnormal operation of the system is expected. If in range check the Power (Circuit) Breaker and look for broken or loosed cable lugs or wiring mistake(s).
12.4.2 Checking Main fuse
Check 25A fuse on the Filter Board - If burnt – check the compressor, fan or any other peripheral that can cause a short. In case of a problematic peripheral - replace it. In case no problematic peripheral, check the resistance on the DC bank (B+ & B- on the Power board), if it is less than 30Ω, replace the controller. Otherwise replace the burnt fuse. In case of frequent burning fuse, replace the controller.
12.4.3 Checking PFC Chock coil
Check PFC chock connection – repair if needed.
Checking the Outdoor Fan Motor1.1.1
Check FAN-Power and FAN-Halls connections - Repair if needed. Rotate the fan slowly by hand. If the fan does not rotate easily, check whether something is obstructing the fan, or if the fan itself is coming into contact with the outer case, preventing it from rotating. Correct if necessary - otherwise, the fan motor bearings have seized. Replace the motor. If the fan rotates easily, use a current probe (“Clamp”) to assure AC current on each phase and it is less than 1A. In case there is no current, check the resistance between the three poles. Assure the three coil resistances are almost the same. The normal value should be between 10Ω to 20Ω.
12-9
TROUBLESHOOTING
SM YAZDCI 1-A.1 GB
Change to Stand-by or Power OFF and re-start - If the fault is still active - replace controller.
12.4.5 aaChecking the Compressor
Check Compressor connections - Repair if needed. Use a current probe (“Clamp”) to assure that there is an AC current on each phase – no more than 15A. In case there is no current, check the resistance between the three poles. Assure the three coil resistances are almost the same (between 0.8Ω to 1.5Ω). Change to Stand-by or Power OFF and re-start - If the fault is still “Active” - replace controller.
12.4.6 Checking the Reverse Valve (RV)
The RV has two parts, Solonoid and valve. Solonoid - Running in heating mode, check the voltage between two pins of reverse valve connector, normal voltage is 230VAC. if no power supply to RV, Check RV operation with direct 230VAC power supply, if OK, replace outdoor controller. Valve - if RV solonoid is OK (as above) but still no heating operation while compressor is On, replace the valve.
12.4.7 Checking the electrical expansion valve (EEV)
The EEV has two parts, drive and valve. When Outdoor unit is powered on, EEV shall run and have click and vibration. For assuring the problem is of the EEV parts, perform the installation test check( 11.6) and if fails and no other indications in the diagnostics, than the problem is with the EEV (one or more). Drive - a step motor; ringed on the valve. Check the drive voltage, should be12VDC. Valve – if drive is OK (as above) but still the indoor unit perform no conditioning replace the valve (no need to take out the refrigerant, just pump down and shut off the main valves).
12.4.8 Checking the thermistors
Check Thermistor connections and wiring - Repair if needed. Check Thermistor resistance – between 0ºC and 40ºC should be between 35KΩ and 5KΩ.
12.4.9 Checking the communication
Change to Stand-by or Power OFF and re-start - If the fault is still “Active” check Indoor to Outdoor Communication wiring and grounding connections (should be less than 2.0Ω) - Repair if needed. If IDU failure – replace IDU controller that does not respond. If ODU failure – replace ODU.
12.4.10 Checking for electromagnetic interferance (EMC problems)
12.4.10.1 EMC troubles to the A/C unit
Locations most susceptible to noise :
1. Locations near broadcast stations where there are strong electromagnetic waves.
2. Locations near amateur radio (short wave) stations.
3. Locations near electronic sewing machines and arc-welding machines.

Either of the following trouble may occur:
1. The unit may stop suddenly during operation.
2. Indicator lamps may flicker
12-10
TROUBLESHOOTING
SM YAZDCI 1-A.1 GB
Correction :
The fundamental concept is to make the system less susceptible to noise (insulate for noise or distance from the noise source):
1. Use shielded wires.
2. Move unit away from the noise source.
12.4.10.2 EMC troubles to near by home appliances
Locations most susceptible to noise :
1. A television or radio is located near the A/C and A/C wiring.
2. The antenna cable for a television or radio is located close to the A/C and A/C wiring.
3. Locations where television and radio signals are weak.
Trouble :
1. Noise appears in the television picture, or the picture is distorted.
2. Static occurs in the radio sound.
Correction
1. Select a separate power source.
2. Keep the A/C and A/C wiring at least 1 meter away from wireless devices and antenna cables.
3. Change the wireless device’s antenna to a high sensitivity antenna.
4. Change the antenna cable to a BS coaxial cable.
5. Use a noise filter (for the wireless device).
6. Use a signal booster.
12.5 Precaution, Advise and Notice Items
12.5.1 High voltage in Outdoor unit controller
Whole controller, including the wires, connected to the Outdoor unit controller may have the potential hazard voltage when power is on. Touching the Outdoor unit controller may cause an electrical shock. Advise: Don’t touch the naked lead wire and don’t insert finger, conductor or anything else into the controller when power is on.
12.5.2 Charged Capacitors
Three large-capacity electrolytic capacitors are used in the Outdoor unit controller. Therefore, charging voltage (380VDC) remains after power down. Discharging takes about one minute after turned off. Touching the Outdoor unit controller before discharging may cause an electrical shock. When open the Outdoor unit controller cover, don’t touch the soldering pin by hand or by any conductive material.
Advise:
Open the Outdoor unit controller cover only after one minute from power off.  Measure the electrolytic capacitors voltage before farther checking controller. 
Additional advises
When disassemble the controller or the front panel, turn off the power supply.  When connecting or disconnecting the connectors on the PCB, hold the whole housing,  don’t pull the wire. There are sharp fringes and sting on shell. Use gloves when disassemble the A/C  units.
