7-2 Night setback control
To use Night setback control (abbreviated to setback control below), click [Functions 3] on the menu, and then
click [Setback Control]. Air conditioning group can be set for this control.
This control prevents indoor dew by heating automatically when the room temperature goes outside of the
specific range during the night.
Note: This control starts heating operation when the control object group stops and the temperature drops below the Min.
temperature. Also this control starts cooling operation when the control object group stops and the temperature rises above
the Max. temperature.
Note: If the room temperature is measured by the air-conditioner's suction temperature sensor, the temperature may not be
correct when the air-conditioner is inactive and the air is not fresh. When the temperature is not measured correctly, switch
the sensor to external temperature sensor (PAC-SE40TSA / PAC-SE41TSA) or remote control sensor.
(1)Select [Use] and set the setback control period.
Note: When [00:00 - 00:00] is set, setback control is active for 24 hours.
(2)Set the control temperature range (Max. and Min.) for each group. For example, suppose [01:00 -
05:00][12°C - --°C] is selected. In this case, heating operation starts automatically when the room
temperature drops below 12°C between 1:00 to 5:00. When the control period is over at 5:00, the set
temperature returns to the original and the operation stops.
Note: During setback operation after the temperature drops below the Min. temperature, when the control period is over or the
room temperature rises to <Min. temperature + 3°C>, the setback control and air conditioning unit stop and the set
temperature returns to the original. In the same way, during setback operation after the temperature rises above the Max.
temperature, when the control period is over or the room temperature drops to < Max. temperature - 3°C>, the setback
control and air conditioning unit stop and the set temperature returns to the original.
Note: When copying settings of a group to another group, click [Copy] button. The screen will change to a selection screen
(yellow-green). Click [Paste] on a group to be copied.
Note: The CITY MULTI model supports a temperature setting range of 12-28°C / 53-83°F when in Heat mode. (When S series
(PUMY) is used, set the temperature at 17°C-28°C / 63-83°F in heat mode.)
