Whenever the sum of the IDU code is outside the range the unit will be forced to Idle Mode and
report: “Mismatch between IDU and ODU models”.
If the unit is forced to Idle Mode, then it will keep checking this condition (the indoor total capacity
test) in order to prevent system latch up. Once the condition is fine, the fault will be cleared and the
unit will proceed to normal operation.

‘No Communication’ fault
If no legal transmission or no message received for 30 seconds, system enters ‘No
Communication’ fault.
When in ‘No Communication’ fault, the system will act as following:
 If there is no communication in all channels, the following will be performed:
1.
The unit changes to SB.
2.
The system will scan all the communication.
3.
Each channel that is identified as ‘no communication’ channel will be referred as
STBY unit.
4.

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.

 Heat sink overheating
 System over power
Operation logic of all protections is the same. The controlled input (CTT, HST, or PWR) is
controlled by changing the protection level using the fuzzy logic algorithm according the input
level and the change rate.
There are two sets of POWER values, the selection of the values are set according to the state

8 min
 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:
1.
2.
3.
4.
No indoor communication channel is connected to non existing tube channel.
The number of the connected/installed indoor unit is set properly.
All the EEVs are connected properly to the right EEV channels.
No mix between the indoor unit’s tubes, each indoor unit must have its own tubes connected
properly to the outdoor unit.
If the rules above are not respected, the test results will make no sense.

Checking the refrigeration system
Checking system pressures and other thermodynamic measures should be done when system
is in technician Mode where the system operates as in fixed settings. The performance curves
given in this manual are given for unit performance in Technician mode when high indoor fan
speed is selected.
For entering technician mode check 11.7.

Diagnostics
12.3.1
Fault Code for Outdoor unit
The last fault occurred in the system will be stored in the EEPROM.
If no fault exist in the system, no fault code will be displayed during normal operation mode.
For single Split units only, when system enters diagnostics mode (through IDU communication),
the last fault code will be displayed even if the system has recover from that fault. The last fault
will be deleted from the EEPROM after the system has exit diagnostics mode (through IDU
communication). The current system operation mode (cool/ heat/ off) will not be changed when
system enters diagnostics.
The coding method is as follow:
STATUS LED is blinking 5 times in 5 seconds, and shut off for the next 5 seconds.
FAULT LED will blink during the same 5 seconds according to the following table

Procedures for checking Main Parts
12.4.1
Checking Mains Voltage
Corrective Action
Check sensor connections or
replace sensor
Replace Indoor controller
Check Indoor to Outdoor wiring
and grounding
Check motor wiring, if ok,
replace motor, if still not ok,
replace Indoor controller.
Switch to Outdoor diagnostics.
No action
No action, unless special
parameters are required for unit
operation.
No action, unless special
parameters are required for unit
operation.
Check Indoor to Outdoor wiring
and grounding
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.
1.1.1
Checking the Outdoor Fan Motor
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.
12-8
SM YAZDCI 1-A.1 GB
TROUBLESHOOTING
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
12.4.10.1
Checking for electromagnetic interferance (EMC problems)
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.
Trouble :
Either of the following trouble may occur:
1. The unit may stop suddenly during operation.
2. Indicator lamps may flicker
SM YAZDCI 1-A.1 GB
12-9
TROUBLESHOOTING
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.
