1-2 Trialoperationshouldbecarriedoutineithercoolingorheatingmode.
•Incoolingmode,selectthelowestprogrammabletemperature;inheatingmode,selectthehighestprogrammable
temperature.
1)Trialoperationmaybedisabledineithermodedependingontheroomtemperature.
Usetheremotecontrollerfortrialoperationasdescribedbelow.
2)Aftertrialoperationiscomplete,setthetemperaturetoanormallevel(78°Fto82°F(26°Cto28°C)incoolingmode,
68°Fto75°F(20°Cto24°C)inheatingmode).
3)Forprotection,thesystemdisablesrestartoperationfor3minutesafteritisturnedoff.
