If the thermostat ON time did continue for 60 min. or longer, then it means that the state wherein the inlet temperature did not reach the set temperature also continued for 60 min. or longer. In the step S11 , if the thermostat ON time did continue for 60 min. or longer, then the method determines whether the difference between the inlet temperature and the set temperature is greater than or equal to the prescribed determination value (i.e., a step S12 ). In the step S12 , if the difference between the inlet temperature and the set temperature is greater than or equal to the determination value, then one hour is added to the reduced comfort time (i.e., a step S13 ).
