Setting conditions
This function is used to define a
minimum time of operation in a given
mode, in order to avoid too frequent
changes of operation mode.
Operation mode does not change
until the minimum transition time
passes, even if the room temperature
reaches the setpoint to shift to the
other operation mode.
If outdoor ambient temperature is
higher than rC, there is no mode
transition to heating in automatic
cooling/heating operation mode,
even if room temperature reaches
the setpoint to switch operation mode
from cooling to heating.
If outdoor ambient temperature is
lower than rd, there is no mode
transition to cooling in automatic
cooling/heating operation mode,
even if room temperature reaches
the setpoint to switch operation mode
from heating to cooling.
If room temperature becomes lower
than this setting, indoor unit operation
is resumed in heating mode by the
setback function.
