14 GL FUNCTIONS 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. 13

15 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). 14

16 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. 15

17 4 Dry Mode Operation Reducing the ambient temperature. This is done cycling ON and OFF indoor and outdoor units according to below. ROOM TEMP DRY LEVEL 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 16

18 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 COOL HEAT OFF ). 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 30 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. 17

19 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 18

20 9.2 Overheat This feature prevents the build up of high pressure in the indoor heat exchanger during heating 19

21 10) I Feel Function sensor equipped in the wireless remote controller (icon I FEEL shown on the display). This feature provides a personalised environment since the temperature can be detected where the remote controller is located. It is possible to de-activate this option pressing the I FEEL button on the remote controller. In this case the I FEEL icon is no longer displayed and room temperature is detected trough the sensor included in the indoor unit. 11) Night Function When this function is active, room temperature changes automatically to compensate for body temperature variations while sleeping. After 10 hours of operation system switches automatically to OFF state. This mode of operation is available both in COOLING and HEATING mode. 20

22 10) 12) Diagnostic With this feature is possible to have a visual signal that a trouble is occurring. In case of no troubles the LEDS status follows its normal function. NOTES The troubles are showed according a priority list that is in case of more than one trouble present, is always showed, at first, the one with the highest priority (1 2 3 etc). Sensor damaged means a situation where sensor is short-circuited or opened. In case of damaged sensors, the system (CM, FMO, FMI etc), if in OFF state, does not start. WRONG MODE SELECTED means a situation where the operating mode chosen with remote controller does not comply with the one allowed by jumpers settings. Priority TROUBLE LEDS status LD1(stby) LD2(opr) LD3(timer) 1 RAT damaged F O O 2 ICT damaged F F O 3 WRONG MODE F F F SELECTED Effects System does not operate O = LED off F = LED blinking 21

23 13) Jumpers configuration Unit is shipped with jumpers set according to the following table: JUMPER STATUS JP1 open JP2 open for H/P models - closed for other versions JP3 open JP4 closed JP5 closed 22

24 14) CONTACTS FOR BUILDING AUTOMATION INPUT CONTACT (J4 - green) - AVAILABLE ONLY IF "BOILER CONNECTION KIT" IS NOT INSTALLED The status of this input affects system operation according to the following: Contact OPEN : system does not operate (always OFF) inputs from wireless remote controller are not processed Contact CLOSED: system operates in the normal way according to the inputs coming from wireless remote controller OUTPUT CONTACT (J12) This connector is directly tied to the contact (normally open) of a power relay which activates every time the following alarm condition occur: RAT damaged ICT damaged In this case when alarm happens, on poles 1 and 3 of J12 connector, 220 VAC-50Hz are available. Max electrical load: 1A- 240VAC 23

25 15) Maintenance address to each unit in order to avoid operation conflicts. Address is set acting on the dip-switches located on the indoor PCB and on the remote controller. The PCB settings must match the corresponding ones on the wireless remote controller How to change address of the air conditioner Dip switch is located on the indoor PCB near the buzzer. Set the PCB to the address desidered UNIT SETTINGS ADDRESS SW1 SW2 1 off off 2 off on 3 on off 4 on on As default switches SW1 and SW2 are in off status (PCB factory state). How to change address on Remote Control Unit Dip switch is located on the battery compartment. 1) Pull out the door and remove the batteries. 2) Set the switch SW1 and SW2 according to the indoor PCB settings (do not act on SW3 and SW4) 3) Insert the batteries and pull on the door As default switches SW1 and SW2 are in off status (remote controller factory state). 24
