USERS FEATURES 2 ZONE
The Following features can be operated by the buttons on the Display unit.
Power On/Off
Press button will turn on the air conditioner or vice versa. When turned on, it will operate according to the setting shown
on the Display unit. The ZONE LED on the Display unit will show the status of the zone operation.
Fan
Press to select the fan speed (high, medium, low or auto speed).
Auto Mode
When the fan speed is put in auto speed, the speed will be adjusted automatically according to the difference between the
room temperature and set temperature.
If the difference is 3C or more, the speed is high.
If the difference is 2C, the speed is medium.
If the difference is 1C or less, the speed is low.
Note: The button cannot be used in DRYmode.
Zone Control
ZONE buttons are used to turn on/off the damper. Jumper at OP5 is for selection of the following algorithm.
a) Jumper OP5 is not inserted: While only one zone is activated then that ZONE button is pressed (both zones are
turned off), the system will delay for 2 minutes and then turn off the operation. All LED will blink as an alarm signal.
During this delayed period if anyZONE button is pressed, the system will turn on the zone damper.
b) Jumper OP5 is inserted: There will be no protection and alarm as per above. If both zones are turned off, the system
will follow the command.
Operating mode
Bypressing MODE button, the air conditioner can be put in
3 operating modes (fan, cool, dry) if the COOL version is ordered.
5 operating modes (fan, cool, dry, heat, auto) if the HEAT/COOL version is ordered.

4
Room Temperature reading (Troom) 2 ZONE
There are 2 room temperature sensors. One is installed at the return air point of Fan Coil Unit. Another is at the Display unit.
Jumper at OP2 is for selection of the following algorithm.
a) Jumper OP2 is not inserted. The room temperature will be read from onlythe sensor at return air point for all modes of
operation.
b) Jumper OP2 is inserted: In COOL or DRY operation, the room temperature will be read from the sensor at the return
air point of FCU. In HEAT operation, the room temperature will be read from the sensor at the Display unit.When any
one of the sensors have failed (short/open circuit), the temperature will be read from another sensor.
Fan
The system will operate as Fan only. The SLEEP, TEMP and TEMP buttons are not used.
Cool
The system will operate as the cooling unit. The compressor will
Operate if T room >T set +1
Stop if T room <T set
However, the compressor issubjected to a 3-minute delay protection each time it stops.
Dry
The system will operate as the Dehumidifier.
Define Ts= setting temperature
Tr= room temperature
Zone A is the area where Tr –Ts> 2oC
Zone B is the area where 0oC <Tr–Ts< 1oC
Zone C is the area where -2oC < Tr–Ts< -1oC
Zone D is the area where Tr–Ts< -4oC
Other temperature rang is called dead band. Which the system is considered to be in the previous zone.

SYSTEM FEATURES 2 ZONE
Watchdog
There is a watchdog circuit to watch the operation of the microprocessor. If it has malfunctioned, this circuit will reset the
microprocessor automatically.
Compressor delay protection
Each time the compressor is off, there will always be a 3 minute time delay before the compressorcan restart. In case of
power interruption, the system will delaythe operation of the compressor in the range of 3-4minutes in random order. This is
to prevent more than one compressor starting at the same time as another, saving the powerboard from „overloading‟.
Compressor minimum on time
Once the compressor starts, it will operate at least 24 seconds.
Non-volatile memory
The system keeps the setting parameters such as on/off status, fan speed, etc. in its non-volatile memory. If there is a power
interruption and back to normal, the control will automaticallyresume its operation with the same setting parameters
(except the sleep and timer function which will be cancelled.)
If there is anychange in the parameter, it will be saved in the non-volatile memory 5 seconds later.
Freeze (Anti-ice) function
In COOL or DRYmode, there is a feature to prevent the evaporator from freezing.
Enter into Freeze process
While in Freeze process
Exit from Freeze process
Tindoor coil < 0oC, and
Comp. stops, and
Tindoor coil > 7oC, or
Comp. runs continuouslymore than 10 min.
Indoor fan at low speed, and
System OFF
There will be an alarm signal at the
Display unit.

7
Defrost Function 2 ZONE
In HEAT mode if the outdoor coil temperature is very low and there is ice formed on the coil. The air conditioner cannot
operate efficiently and the compressor may be damaged. The defrost function will be activated, it will reverse the system‟s
mode operation from heat to cool. The heat will be transferred from the indoor unit to the outdoor coil. Meanwhile the indoor
fan willbe stopped to protect the user in the room from the cold draught.
As soon as the outdoor coil temperature is below 3oC, the defrost timer starts. If the temperature is above 3oC more than 2
minutes, the timer is reset.
The defrost process is activated if
a) The compressor has been running continuously more than 5 minutes and the system is put in heat mode.
b) The defrost timer time meets one of the below conditions
The outdoor coil temperature is decreased from +3 to -8oC (line AB) during 30-60 minutes and remains at -
8oC or below, more than 5 minutes.
The outdoor coil temperature is reduced from +3 to -4oC (line AC) during 60-120 minutes and remains at
-4oC or below, more than 5 minutes.
The outdoor coil temperature is reduced from +3 to -2oC (line AD) after 120 minutes and remains at -2oC or
below, more than 5 minutes.
While the defrost function is activated,
The indoor fan stops and
The outdoor fan stops while the compressor runs and
The reversing valve is not energized (running in cool mode) and
The LED on the display unit blinks.
The system will go back to the normal stage if
The outdoor coil temperature is above 30oC or
The defrost function operates more than 10 minutes or
The air conditioner is turned off.
In COOL or DRYmode if the compressor has been operating more than 3 minutes but the indoor coil temperature is still
above 25oC, the compressor has failed. The controller will send the alarm by blinking LED on the display.
To exit is byturning off the air conditioner or changing the mode of operation of Fan or Heat.

8
Heat Fail 2 ZONE
In HEAT mode and not in the Defrost status if the compressor has been operating morethan the 3 minutes but the indoor coil
temperature is still below 25oC, the compressor has failed. The controller will send the alarm by blinking LED on the display.
To exit is byturning off the air conditioner or changing the mode of operation.
