5 When the system is operated,
an error code is displayed on
the remote controllers.
6 Even though no error code is
displayed on Lossnay remote
controller (PZ-61DR-E), an
error code is displayed on
Dx-coil unit remote controller
(PZ-01RC).
7 Even though an error code is
displayed on Lossnay remote
controller (PZ-61DR-E), no
error code is displayed on
Dx-coil unit remote controller
(PZ-01RC).
8 Lossnay remote control-
ler (PZ-61DR-E) displays a
supply air temperature that is
different from actual tempera-
ture.
9 "System error 2" is displayed
on Dx-coil unit remote con-
troller (PZ-01RC).
10 Operation mode and target
temperature are not dis-
played on the system control-
lers.
11 Even when operation mode
or target temperature is set
by schedule setting of the
system controllers, the opera-
tion mode or target tempera-
ture of the Dx-coil unit is not
changed.
12 Lossnay remote controller
(PZ-61DR-E) does not start
and continues to display
"Please Wait."
Error code "6831" is dis-
played.
Cause
Some error, which can be detected
only during operation, has occurred.
The error code "P1" may be dis-
played on Dx-coil unit remote con-
troller (PZ-01RC), even though no
error code is displayed on Lossnay
remote controller (PZ-61DR-E).
The Dx-coil unit is stopping.
The function selection switch
(SW11-3: Selecting of the pattern
when an error occurs) on PCB B is
set to ON "Pattern B."
Communication error between PCB
A and PCB B of the Dx-coil unit
Calculated supply air temperature
display is not available.
Dx-coil unit remote controller (PZ-
01RC) is connected to the Lossnay
unit.
The system controllers do not dis-
play operation mode and target
temperature of the Dx-coil unit.
Schedule setting of the system con-
trollers cannot be used to change
the operation mode or target tem-
perature of the Dx-coil unit.
Lossnay remote controller (PZ-
61DR-E) is connected to the Dx-coil
unit.

Corrective action
See 7-3 (3).
See 7-3 (1).
Remote controller (PZ-01RC) does
not display the error code when the
Dx-coil unit is stopped.
When the switch (SW11-3) is set to
ON, remote controller (PZ-01RC)
does not display the error code dur-
ing the "Fan" mode of the Dx-coil
unit.
See 7-3 (1).
Set the function setting (No. 38)
of Lossnay remote controller (PZ-
61DR-E) to 0: No use of calculated
supply air temperature display.
Check the model name of the re-
mote controller, and make sure to
connect Lossnay remote controller
(PZ-61DR-E) to the Lossnay unit.
It is not a failure.

connect Dx-coil unit remote control-
ler (PZ-01RC) to the Dx-coil unit.
