11. pre set temperature St is reached evaporator temperature gt St when the hot gas valve output is switched back OFF and fan switched back ON standard working condition is restored OLIMPIA SPLENDID According to the above description the parameters Co and Ft refer to defrosting start condition higher Co and lower Ft values means higher ice accumulation on evaporator heat exchanger before defrosting whereas the parameter St refers to defrosting exit condition lower St value means shorter function duration As the compressor keeps always ON during defrost operations the hot gas valve activation period can be shorter than Cf minutes If the frost condition evaporator temperature lt Ft compressor ON and hot gas valve output OFF lasts for less than Co minutes then no defrosting operations shall occur In dehumidification mode if frost condition is detected and RH set point is reached within Co minutes the unit shall switch off the compressor and the fan 30 seconds later as usual and the defrosting function currently running is not completed If RH set point is reached during the hot gas valve output activation the unit must complete the defrosting function currently running before switching off the compressor keeps working with compressor and hot gas valve output ON and fan OFF until the evaporator temperature reaches St then all outputs can be finally switched OFF If Stand by mode is selected during any defrost fu
