(6) Procedures for replacing the circuit boards

Notes
• Before removing the circuit boards for replacement, check the following Steps 1 and 2.
• When the Lossnay remote controller PZ-61DR-E is connected, make sure to replace the circuit boards as
described in the Steps.
Step
1

Check the system configuration.

Check if PZ-61DR-E is connected to the circuit board to be replaced.
The following describes settings required when replacing the circuit boards per the
system configuration.
Check which system configuration is applicable, and then replace the circuit boards.
Lossnay
(A)
Remote controller cable
PZ-61DR-E
(B)
City Multi indoor unit
2

Check the settings on PZ-61DR-E.

Regarding the settings on PZ-61DR-E, prepare the data recorded at the time of
installation (setting status record, etc.).
In the case there is no data recorded at the time of installation, and if the Lossnay
unit can be operated with PZ-61DR-E, use the form in "(8) Setting status record (page
48)" to record the settings on PZ-61DR-E.
To check the settings on PZ-61DR-E, see the Lossnay technical manual or remote
controller manual.
On the function setting screen of PZ-61DR-E, display the M-NET address of the
•
Lossnay unit for which you wish to check the settings.
The address can be checked by the address setting switches (SA1 and SA2) on the
•
Lossnay circuit board.
3
Setting status record of the address setting switches and function selection switches on the circuit board
Using the form in "(8) Setting status record (page 48)", record setting statuses nec-
essary for replacing the circuit board.
Remove the control box cover, and check the setting status of each switch on the
circuit board.
If the function setting statuses were recorded at the time of installation, this step can
be skipped.
