Deadband And Set Temperature - Fujitsu UTY-RNRUZ2 Operating Manual

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.
