3. In the Differential combo box (12), select the thermal difference. The range of values you can
set is 0 to 7°C, in increments of 1°C.
"Differential" is the tolerance for the indoor unit's setpoint. When the difference between the room
temperature and the representative setpoint exceeds this thermal difference, the operation mode
changes.
When the operation mode changes from cooling to heating, the setpoint is decreased by this
thermal difference.
When the operation mode changes from heating to cooling, the setpoint is increased by this
thermal difference.
Example: If the indoor unit's setpoint: 22°C and differential: 4°C, when operation changes to
cooling because the indoor temperature exceeds 26°C, the setpoint changes to 26°C.
4. Select one from the three methods below for assessing the indoor temperature and setpoint for
the group in (13). Average is selected by default.
Fixed: Uses the room temperature information and setpoint of the indoor unit registered at the
top of the group as representative room temperature and representative setpoint. In this
mode, information of the indoor unit registered at the top is used even when that indoor
unit is stopped. However, this function does not work if the operation mode of that indoor
unit is other than Cool, Heat, or Automatic, is Communication error, or Maintenance.
Operating: Searches for an indoor unit in the group operating in Cool, Heat, or Automatic mode,
and uses the indoor temperature information and setpoint of that indoor unit as the
representative indoor temperature and setpoint. The order in which an operating
indoor unit is searched is the order in which the management point is registered with
the group. If none of the indoor units in the group satisfies the condition, the indoor
unit registered at the top, as in the Fixed method is referenced. In this mode, an
indoor unit stopped by the Heating Mode Optimization is considered operating.
Average: Uses the average room temperature information and average setpoint of indoor units
of the group operating in Cool, Heat, or Automatic mode as representative room
temperature and representative setpoint. If none of the indoor units in the group
satisfies the condition, the indoor unit registered at the top, as in the Fixed method is
referenced. In this mode, an indoor unit stopped by the Heating Mode Optimization is
considered operating.
