Temporary switch
For an temporary operation when the remote

TEMPORARY switch to COOL or AUTO side.
If setting the switch to COOL side, the cooling
operation can be confirmed even while the
thermostat is OFF when temperature of the return
air is low.
Auto Restart switch
The Auto Restart switch is useful for restarting the
system when the outside power supply is unstable
by an instantaneous power failure, etc. Do not use
this switch when the unit itself is in trouble.
For usual operation by the remote controller, set
this switch to OFF. (Otherwise, an operation by the
remote controller is unavailable.)
