5-7 Forced ModeIn this mode the system operates (COOLING or HEATING mode – fixed settings) or is switched off bymeans of the MODE button of the indoor unit control board. The operation modes can be selectedpressing the button in a cyclic way (OFF COOL HEAT OFF…). The settings are:COOLING modeSET POINT temperature = 25°CFAN SPEED = HIGHHEATING modeSET POINT temperature = 21°CFAN SPEED = HIGH5-8 Protection operations in Cool and Dry ModeThis protection prevents ice formation on the indoor coil heat exchanger. The protection is activated bythe indoor coil temperature (ICT sensor) and only after 6 minutes of compressor operation. Thisprotection acts in 2 levels:LEVEL 1INDOOR FAN SPEED: ANY (as selected from remote controller)COMPRESSOR: ONOUTDOOR FAN: cycling (30 seconds ON 30 seconds OFF).LEVEL 2INDOOR FAN SPEED: ANY (as selected from remote controller)COMPRESSOR: OFF for at least 6 minutes and until ICT ≥ 8°COUTDOOR FAN: OFF for at least 6 minutes and until ICT ≥ 8°CThe system exit this protection routine when ICT temperature rises above 8°C.22

As soon as the protection mode is exited speed can be changed manually through theremote controller. The protection acts in the following5-9.2 DefrostThe defrost process is controlled by a detection algorithm designed in order to mantain optimalutilization of the heat pump capacity especially during negative outdoor temperature conditions.During DEFROST OPERATION the main components operates according to the following chart:30 seconds 30 seconds6 seconds 6 seconds23
