4-4 Deadband and set temperature
The Cool and Heat set temperature difference at Custom
Auto cannot be less than the deadband set value. If the Cool
and Heat set temperature difference is the same as the
deadband set value, the Heat setting drops by the amount
of drop of the Cool setting and the Cool setting rises by the
amount of rise of the Heat setting. When the Cool set value
reaches the upper limit, Heat setting exceeding the dead-
band set value cannot be set.
4-5 Occupied state
In the following cases, the operation button needs to be
pressed twice:
• When stopping the operating indoor unit while “Unoccu-
pied” is displayed, press the operation button once to set
to “Occupied” and press it again to set to “Unoccupied”.
Then the indoor unit stops.
• When operating the stopped indoor unit while “Occupied”
is displayed, press the operation button once to set to
“Unoccupied” and press it again to set to “Occupied”.
Then the indoor unit operates.
In the following cases, the occupied state does not switch to
“Occupied” even if the indoor unit starts operation:
• Anti freeze operation
