1 Cool Mode Operation
In Cool mode , the operation of Compressor ( CM ) , Solenoid Valve ( SV ) and Indoor Fan ( FMI ) are
determined by the difference between the Room Temperature (RAT) and the Set Point Temperature (SPT)
as in the graph above.
Notes:
a. In this graph, the FMI is operating in the"Auto Fan Speed" setting. If the user has selcted the low,
medium or high fan speed, the FMI will run constantly at that speed only.
b. In addition to the value of ( RAT-SPT ) , the operations of the relays are also controlled by protection
delays.For example,(a) the minimum On/Off time of the ( CM ) is 3min respectively, and (b) the FMI can
change speed only after it has operated at de same speed for 30sec.wen in autofan setting and 1sec.
for H/M/L setting.
FUNCTIONS
GL
14

2 Heat Mode Operation
The Heating mode operation is similar to the Cooling mode operation.The compressor CM,solenoid valve SV and
fan motor indoor FMI are mainly controlled by the value of ( RAT – SPT ).In the graph above, the FMI is operating
in AUTO speed mode. Therefore, the FMI speed changes automatically according to the ( RAT - SPT ).
NOTES
1. After the CM has stopped, the FMI runs for 30s in order to purge heat from the indoor coil.
2. The FMI will not be turned on until the indoor coil temperature is warm enough to prevent the supply of
cool air (see COLD DRAFT PREVENTION feature for details).
The indoor fan can change speed only after it has operated at the same speed for 30 sec if in AUTO and
1 sec for the other settings (High, Med, Low).
15

3 Auto (Cool/Heat) Mode Operation
In Auto Mode, the unit switches automatically between the Auto Cooling and Auto Heating in order to
maintain the room temperature (RAT) at the prescribed set point (SPT).
The switching between the two modes is according to the above graph.
Refer to the sections 1.COOLING MODE and 2.HEATING MODE for system operation details.
16

4 Dry Mode Operation
Reducing the ambient temperature. This is done cycling ON and OFF indoor and outdoor units
according to below.
ROOM DRY LEVEL
TEMP
≥SPT+2°C LEVEL 0 Operation according to COOLING mode
CM on
< SPT+2°C LEVEL 1 FMO on
≥SPT-1°C FMI switches between L and off (30 seconds)
RV off
CM switches 9 minutes off and 3 minutes on
< SPT-1°C LEVEL 2 FMO switches 9 minutes off and 3 minutes ON
≥15°C FMI switches off and L during CM operation
RV off
CM off
< 15°C DRY OFF ZONE FMO off
FMI off
RV off
SPT = Set Point Temperature
5) Fan Mode Operation
With this mode, the indoor fan is turned on while CM, FMO and RV stay off all the time.
The user can select between 3 speeds: HIGH, MEDIUM and LOW.
6) Auto Fan speed
With this option selected, the indoor fan speed changes automatically according to the difference
between the detected air temperature (RAT sensor) and the set point (SPT):
COOLING MODE
2 ≤(RAT – SPT): HIGH speed
1 ≤(RAT – SPT) <2: MEDIUM speed
(RAT – SPT) <1: LOW speed
HEATING MODE
2 ≤(SPT - RAT): HIGH speed
(SPT - RAT) <2: MEDIUM speed
NOTE
SPT = Set Point Temperature
17

7) Forcede mode
means of the OPERATION button on the front panel. The operation modes can be selected
pressing the button in a cyclic way (OFF ÖCOOL ÖHEAT ÖOFF…). The settings are:
COOLING mode
SET POINT temperature = 25°C
FAN SPEED = HIGH
HEATING mode
SET POINT temperature = 21°C
FAN SPEED = HIGH
See also paragraph 15 for additional details.
8) Protection operations in Cool and Dry Mode
8.1 Freeze-up
This protection prevents ice formation on the indoor coil heat exchanger. The protection is activated by
the indoor coil temperature (ICT sensor) and only after 6 minutes of compressor operation. This
protection acts in 2 levels:
LEVEL 1
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: ON
OUTDOOR FAN: cycling (30 seconds ON B30 seconds OFF).
DRAIN PUMP: operates according to paragraph 17
LEVEL 2
INDOOR FAN SPEED: ANY (as selected from remote controller)
COMPRESSOR: OFF for at least 6 minutes and until ICT ≥8°C
OUTDOOR FAN: OFF for at least 6 minutes and until ICT ≥8°C
DRAIN PUMP: always ON ( stops when exiting the protection)
The system exit this protection routine when ICT temperature rises above 8°C.
18

9) Protection operations in Heat Mode
9.1 Cold draft
This feature prevents the supply of cold air forcing the indoor fan to a speed which cannot be changed
by the user. As soon as the protection mode is exited speed can be changed manually through the
remote controller. The protection acts in the following
19

9.2 Overheat
This feature prevents the build up of high pressure in the indoor heat exchanger during heating
