The pulse signal can be turned
ON/OFF.
Operation/Fault signal can be
received at a distant place
(DC 12V signal).
Operation/Fault signal can be received
at a distant place (when channeled
through the PAC-SF40RM →
no-voltage signal, when channeled
through the PAC-SA88HA-E →
DC 12V signal).
Weekly timer:
ON/OFF and up to 8 pattern
temperatures can be set for each
calendar day. (Initial setting)
Simple timer:
ON/OFF can be set once each
within 72 hr. in a unit of one hour.

after elapsing a certain time.
Set time can be changed from
30 min. to 4 hr. at 30 min. intervals.
*Simple timer and Auto off timer cannot be
used at the same time.
Mounting the adapter for M-NET
connection to the outdoor unit
allows MELANS (M-NET system)
connection.
Allows centralized control by
MELANS.
LOSSNAY can be connected to the
indoor unit.
