2 Fan speed control by function setting
The following fan speed control can be set with PZ-60DR-E or the function selection switch (SW2) on the
Lossnay circuit board.
Function
Extra High This switches the settable fan speed from the remote control-
/High ler and the system controller. Set this when there is a need for
Fan speed large air volume, or when there is a long duct line.
selection When set to High fan speed, High/Low fan speed can be set,
and when set to Extra High fan speed, Extra High/Low fan
speed can be set.
Display

Multi ven- This switches the settable fan speed from the remote controller
tilation and the system controller to a fixed Low fan speed. The sup-
mode ply/exhaust balance is adjusted to suit the usage environment
or the place of installation.
Operation

will follow the fan speed set by the remote controller or system
controller.

Details
The fan speed display of the remote controller,
and the system controller will be the same for
either Extra High or High.
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/Extra Low fan speed. Other remote con-
trollers and system controllers can change the fan
speed display; however, the fan will remain fixed
at Low fan speed.
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.
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.
