The fan speed can be selected either High or Extra High, when
the speed is set High with the remote controller or the system
controller. Select Extra High when large air volume is required,
or when the ductwork length is long.
When set to High fan speed, High/Low fan speed can be
switched, and when set to Extra High fan speed, Extra High/
Low fan speed can be switched.

When PZ-60DR-E will not be used in a system of
multiple Lossnay units, set the function selection
switches on the Lossnay circuit board for each
unit.
The fan speed display of the remote controller,
and the system controller will be the same for
either Extra High or High.

is adjusted to suit the usage environment or the place of instal-
lation.

During the first 30 minutes of operation, operation will be at
High (Extra High) fan speed. This is used when rapid ventila-
tion is desired at the time of starting operation.
After 30 minutes have elapsed since starting operation, or
when the fan speed set from the remote controller or the sys-
tem controller has been changed to something other than High
fan speed, power ventilation will be cancelled and the system
will follow the fan speed set by the remote controller or system
controller.

When PZ-60DR-E will not be used in a system of
multiple Lossnay units, set the function selection
switches on the Lossnay circuit board for each
unit.
When both supply and exhaust are set to the multi
ventilation mode, due to operation restrictions
PZ-60DR-E cannot be switched to a setting other
than Low fan speed. Other remote controllers and
system controllers can change the fan speed dis-
play; however, the fan will remain fixed at Low fan
speed.
Operation
Multiple
units
When PZ-60DR-E will not be used in a system of
multiple Lossnay units, set the function selection
switches on the Lossnay circuit board for each
unit.
During power ventilation, PZ-60DR-E will display
“POWER VENT START”. Other remote control-
lers and system controllers will display the set fan
speed, even during power supply exhaust opera-
tion.
