This document is to address a problem with the ACPA400 cool set point. If a customer cannot change the cool set point, or when they change the cool set point it reverts back to the previous set point. The reason this would happen is because the scheduling is enabled on the unit. If the scheduling is enabled it will over ride any change to the set point.
Path: Main Menu > Setup > Operating Schedule. Program up to eight sets of environmental controls that run according to the time and day.
Scheduling: on/off. Select Off to use the default schedule, or on to use the programmed schedules.
