: Control execution condition
The relationship between room temperature, set temperature, and operation /
stop status is shown in the figure below.
The operation period of the control is every 5 minutes after the system power is
turned on, and the operation is executed when the control conditions are met at
each timing.
This function performs start / stop control based on the relationship between the
set temperature and the room temperature (intake air temperature) of the air
conditioner in heating operation. The control conditions are described below.
Operation interruption control in heating mode (Stop control)
When the room temperature for the air conditioner in heating operation becomes
higher than the set tempe 1
°
C, the air conditioner is stopped. The
stoppage (operation interruption) by this control is processed as “in-operation of
the air conditioner” on the monitoring screen of the unit.
Operation restart control in heating mode (start control)
When the room temperature for the air conditioner in interruption becomes lower
than the set temperature – 1
°
C by this function, the air conditioner is
restarted.
Enabled-to-disabled Automatic Changeover control (start control)
When the setting of this function for the air conditioner is changed from enabled
to disabled during operation interruption, the operation is restarted.
Operation mode Automatic Changeover control (Start control)
When the operation mode of the air conditioner in interruption is changed by this
function, the air conditioner is restarted.

: Precautions for the use of this control
1.The stoppage (operation interruption) by this control is processed as “in-
operation of the air conditioner” on the monitoring screen of the unit. As a result,
this status is indicated as “Stop” on the remote controller of the air conditioner,
and as “In-operation” on the monitoring screen of the unit.
2.As explained above (item 1), because the display on the remote controller
during operation interruption by this control is “Stop,” the user may not perform
the stop operation even at the scheduled time of system stoppage, resulting in
forget-to-stop error. Therefore, it is recommended that a measure against forget-
to-stop error be executed by the scheduled control of the unit or other
appropriate methods.
