5-3-2. Night Setback Control
The Night Setback Control function (hereafter abbreviated as Setback Control) prevents indoor condensation by
performing heating operation automatically when the room temperature goes outside of the specific range during
the night. Touch [Function2] in the menu bar, and then touch [Setback].
Heating operation starts when a given group is stopped and the room temperature drops below the specified
minimum temperature.
Note: The Setback Control function also prevents excessive temperature rise by performing cooling operation automatically when
the room temperature goes outside of the specific range. Cooling operation starts when a given group is stopped and the
room temperature rises above the specified maximum temperature.
Note: If the operation settings (on/off, operation mode, or set temperature) is changed from a local remote controller during the
Setback Control, the settings selected before the Setback Control will not be restored.
Note: If the room temperature is measured by the return air temperature sensor on the air conditioning unit, the measured value
may not be an accurate representation of the temperature in the room, especially when the air conditioning unit is stopped
and the room air is stagnant. When this is the case, use an external temperature sensor (PAC-SE40TSA) or remote
controller sensor to measure the room temperature.
Note: The Setback Control may not be accessible if logged in as a building manager.
Note: The [Controller] setting will appear (only on the AE-200’s LCD) when the [System Exp] setting on the [Unit Info.] screen is set
to [Expand]. Switch the [Controller] setting between [AE200] and [Exp1] through [Exp4] to make settings for each AE-200,
AE-50, and EW-50 individually.
Important
● Setback Control settings for the AE-50/EW-50 must be made with the AE-50/EW-50 properly connected to ensure proper
settings. Those settings made without the connection of AE-50/EW-50 will not be reflected.
(1) Touch the [Control Time] button to display the settings
screen.
Set the [Setback] setting to [Use], set the time period in
which Setback Control is performed, and then touch [OK].
Note: When [00: 00 - 00: 00] is selected, Setback Control is active
for 24 hours.
