(OA) air temperatures and automatically select the "Lossnay ventilation"
or "Bypass ventilation". With this mode, however, priority is given to the
"Bypass ventilation".
* This setting reflects to the night purge operation condition.
OFF ON
When outdoor temperature (OA) is 82.4˚F (28˚C) or higher within
24 hours, then Bypass ventilation starts by the comparison
OA and RA temperature. The lowest RA temperature of Bypass
7 operation is 75.2˚F (24˚C) (factory setting)
When the night purge is set by the remote controller PZ-
60DR-E, night purge operation starts at a temperature of
SW2 82.4˚F (28˚C) (within 24 hours).
When outdoor temperature (OA) is 62.6˚F (17˚C) or
higher within 24 hours, then Bypass ventilation starts by
the comparison OA and RA temperature. The lowest RA
7 temperature of Bypass operation is 66.2˚F (19˚C)
When the night purge is set by the remote controller PZ-
