5-3 Setting up the Auto Changeover

The Auto Changeover function allows you to automatically toggle the operation mode of air
conditioners that do not support the "Automatic" mode, depending on the change in the room
temperature. Furthermore, this functions automatically changes the setpoint when it changes the
operation mode.
If this function is enabled, the function assesses the control conditions from the representative
room temperature and representative setpoint every 5 minutes and toggles the operation mode
when the conditions for toggling are satisfied. No assessment is performed in the 30 minutes that
follows an operation mode change to cooling. However, if the setpoint is changed, an assessment
is performed immediately, and then, once every 5 minutes.
The assessment of the control condition is performed according to the following four patterns
depending on the thermal difference settings. If the thermal difference setting is 0 to 4°F, the
operation mode is changed to keep the thermal preservation range constant at 6°F.
When the thermal difference is 5°F or more
• When Representative suction temperature – Representative setpoint (Heat) > Thermal difference,
operation mode is changed from Heat to Cool
• When Representative setpoint (Cool) – Representative suction temperature > Thermal difference,
operation mode is changed from Cool to Heat
