Indoor Fan Control
10 Indoor fan speeds are determined for each model. 5 speeds for each mode cool/dry/fan
or heat.
When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate
constantly at set speed.
When Auto Fan is selected, indoor unit controller can operate in all speeds. The actual
speed is set according to the cool/heat load.
11.4.1.1 Turbo Speed
The Turbo speed is activated during the first 30 minutes of unit operation when auto fan
speed is selected and under the following conditions:
Difference between set point and actual room temperature is higher than 3 degrees.
Room temperature is higher than 22°C for cooling or less than 25°C for heating.
11.4.2
Cool Mode
NLOAD is calculated according to the difference between actual room temperature and user
set point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be adjusted automatically according to the calculated
NLOAD.
11.4.3
Heat Mode
NLOAD is calculated according to the difference between actual room temperature and user
set point temperature by PI control.
In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed.
In AutoFan user setting, fan speed will be adjusted automatically according to the calculated
NLOAD.
11.4.3.1 Temperature Compensation
In wall mounted, ducted, and cassette models, 3 degrees are reduced from room
temperature reading (except when in I-Feel mode), to compensate for temperature
difference between high and low areas in the heated room, and for coil heat radiation on
room thermistor.
The temperature compensation can be enabled/disabled by shortening of J2 on the indoor

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 Æ COOL
Short Æ HEAT
The ODU will go to SB if all the IDU are at SB or at different modes.
4.

Outdoor Fan Speed Control
11.5.4.1 General Rules
o
OFAN operates between OFMinRPM to OFMaxRPM.
o
The OFAN speed is consecutive and related to the high pressure of the system.
o
The fan speed is also related to compressor speed, outdoor temperature and to protections.
11.5.4.2 Behavior when there is a failure in OFAN
Whenever OFAN fault occurs the compressor will be stopped immediately, except during
deicing protection, then the OFAN will be enabled to be started for maximum 5 times. This rule
is enabled each time the ODU switches to heat/cool modes.
11.5.4.3 Protection Behavior
•
When in total IDU protection level is different than normal, the OFAN will reduce
OFSpdReducePrtC and OFSpdReducePrtH RPM for cool and heat respectively.
•
In cool mode the OFAN will operate according to CTT or HST protection level:
Protection level
SR, D1 or D2
Stop-Compressor
Action
OFAN will add 100 RPM to the target speed
continue to operate for maximum 2 minutes at it last speed or until normal level is
achieved.
11.5.4.4 OFAN Force On condition
If HST is higher than 70°C or defined as “HST bad”, OFAN will remain ON at the last operating
speed for maximum 2 minutes after COMP is OFF.
11.5.4.5 Night mode
Upon receiving night mode, the OFAN will be limited to max NightRPM speed only in Cool. It
will be back to its normal operation when receiving the mode is cleared.
11.5.5
RV State Setting
During heat mode (except during Deicing) RV is ON.
During cool/SB mode RV is OFF.
RV status will be changed only if COMP is OFF for 3 minutes or more.

ODU Protections
There are 3 ODU protections:
•
Compressor overheating
•
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
of the Power-Shed dry contact input.
Power-Shed input open Æ Power1
Power-Shed input sort Æ Power2
The following table summarizes the basic levels of each protection.

Deicing Starting Conditions
Deicing operation will start when either one of the following conditions exist:
Case 1: OCT < OAT – DST AND TLD > DI
Case 2: OCT < OAT – 12 AND TLD > 30 minutes.
Case 3: OCT is Invalid AND TLD > DI
Case 4: Unit is just switched to STBY AND OCT < OAT – DST
Case 5: NLOAD = 0 AND OCT < OAT - DST
Case 6: OAT is invalid AND OCT< DST AND TLD > DI AND Compressor ON Time > CTMR

OAT – Outdoor Air Temperature
TLD – Time from Last Deicing
DI – Deicing Interval (Time Interval between Two Deicing)
DST – Deicing static threshold (Temperature)
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.

Procedures for checking Main Parts
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 20A 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 30, 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.
Dis-connect the chock from the controller wire extensions, check if the 2 wires of the chock are
shorted. If shorted (OK) check between each wire and the metal box. If shorted replace chock, if
not (OK), open the controller top cover and check if the wire extensions are connected well and
if shorted. If not shorted, replace wires, if shorted (OK) than might be a controller problem –
replace controller.
12.4.4
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.
SM TQDCI 1-A.1 GB
CONTENTS
12-5
TROUBLESHOOTING
The normal value should be between 10Ω to 20Ω.
Change to Stand-by or Power OFF and re-start - If the fault is still active - replace controller.
12.4.5
Checking 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 (see 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 termistors
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.
Trouble :
Either of the following trouble may occur:
1. The unit may stop suddenly during operation.
2. Indicator lamps may flicker
Correction :
The fundamental concept is to make the system less susceptible to noise

CONTENTS
SM TQDCI 1-A.1 GB
TROUBLESHOOTING
(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.

12.5.1
Precaution, Advise and Notice Items
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.
