SECTION I: USERI.4 RAPID OPERATING GUIDEI.4.1 AUTOMATIC MODEWhen t he automatic programme AUTO is selected, the unit mayoperate i n COOLING or HEATING mode depending on t he temperaturedifference i n plac e bet ween the ambient temperat ure and thetemperature s elect ed on the remot e control.The unit will op erate in mode: If:cooling AT-ST > 1 °Cfan -1 °C ≤ AT-ST ≤ 1 °Cheating AT-ST < 1 °CAT = ambient t emperature ST = selec ted temperat ureI.4.2COOLING MODETo set the cooling mode COOL, proceed as f ollows :• select t he c ooling pr ogramme by pressi ng the MODE key (1) untilthe word COO L appears on t he display;• adjust the desired temperatur e by pressing t he TEMP keys (2). Thedisplay s hows val ues from 17 °C t o 30 °C;• adjust the fan s peed by pr essing the FAN SPEED key (3), c hoosingbet ween AUTO and the other s peeds HI GH-MED-LOW;• point the remot e control at t he unit recei ver and press the ON/OFFkey ON/OFF (4);• adjust the air flow i n keepi ng with requirements by using the SWINGkey (5) or AIR DIRECTION key ( 6).Once these adjustments have been made, they will be offered when theunit is s witched bac k on.If received b y the unit, ever y sign al tran smitted b y the remotecontrol is confirmed b y a double "beep”.I.4.3DEHUMIDIFICATION MODETo set the dehumidific ation mode DRY, proceed as f ollows:• select t he dehumidification programme by pressing the MODE key(1) until t he wor d DRY appears on t he display;• adjust the desired temperatur e by pressing t he TEMP keys (2). Thedisplay s hows val ues from 17 °C t o 30 °C;• point the remot e control at t he unit recei ver and press the ON/OFFkey ON/OFF (4);• adjust the air flow i n keepi ng with requirements by using the SWINGkey (5) or AIR DIRECTION key ( 6);Once these adjustments have been made, they will be offered when theunit is s witched bac k on.If received b y the unit, ever y sign al tran smitted b y the remotecontrol is confirmed b y a double "beep”.When t he dehumidification programme DRY is selec ted, t he unitoperates wit h a free temperat ure setting, progressi vel y lowering theambient temperat ure and humidit y.When t he dehumidification programme DRY is in operation, t he F ANSPEED button cannot be used.I.4.4 HEATING MODETo set the heati ng mode HEAT, proc eed as follows:• select t he heating programme by pressi ng the MODE key ( 1) untilthe word HEAT appears on the display;• adjust the desired temperatur e by pressing t he TEMP keys (2).

It prevents the f an from starting up if the inlet watertemperature at t he exchanger is above 22°C for t he mini mum speedand 25°C for t he medium and maximum speed, t hus preventingunpl easant hot air flows. T his situation could occur t he first time the unitis started or after long periods out of use. When the ANTI-HEATINGfuncti on is acti ve, the red DEF./F AN LED is on.I.4.6.2 ANTI-COOLINGThe ANTI-COOLING function is envisaged for the HEAT operati ngmode. It prevents the fan from starting up if the i nlet water temperatureat t he exchanger is below 28°C f or the minimum speed and 32°C for t hemedium speed and maxi mum s peed, thus preventi ng unpleas ant coldair flows . This sit uation c ould occur t he first time t he unit is started orafter long periods out of use.When t he ANTI-COOLING func tion is acti ve, t he red DEF./FAN LED ison.I.4.6.3 MEMORYREMOTE CONTROlAfter a power cut, ON/OFF from the remote control or an alar m, theappliance will recommence operation in the mode in which it wasoperating at the moment t he power c ut occurred. If the TIMER f unctionwas acti ve before the power cut, this function is deacti vated.W IRED CONTROL PANELAfter a power cut , t he applianc e is in O ff st ate. When it is t urned onagain, it res tarts in Auto mode with set point 24°C.After On/Off from the wired control panel or an alarm the appliance willrecommence operation in the mode in which it was operating at themoment t he power cut occurred. If the TIMER f uncti on was acti vebef ore t he power c ut, this f uncti on is deacti vat ed.IMPORTANT !The unit fan stops wh en the set temperature isreach ed and is then automaticall y reactivated atminimum sp eed to prevent air str atificationphenomena in the vicinit y of the appliance.33
