Outdoor Unit Control Pcb (Cr-C906Vh8P) - Panasonic S-200PE2E5 Technical Data & Service Manual

4-5. Outdoor Unit Control PCB (CR-C906VH8P)

Explanation of Functions
2P (white): Automatic address setting switch
Auto Address
pin
• If the system address switch (S002: set to 0 at time of shipment) setting is other than "0"(central
(CN047)
control), press this switch once to automatically set the addresses at all indoor units which are
in the same system, and are connected to that outdoor unit.
During automatic address setting, the 2 LEDs (red) on the outdoor unit control PCB blink
alternately. (Pressing this switch again stops automatic address setting.)
• If automatic address setting is currently in progress at another system that is subject to central
control, only LED 1 on the outdoor unit control PCB blinks to indicate that automatic address
setting is in progress at another unit. If automatic address setting is in progress at another unit,
automatic address setting cannot be made at this unit, even if S001 is pressed.
* After the power is turned ON, automatic address setting will not be functioned for over 1
minute and 30 seconds.
Rotary switch (10 positions, black): System address setting switch
S002
• This switch is set to 0 (1 system control) at the time of shipment. However the address for
each system must be set when multiple systems are controlled or when central control is
used.
(Figure 1)
• If the system address is set to 0, automatic address setting is started when the power is
turned ON. Therefore it is not necessary to use switch SW01 and perform automatic address
setting in the case of single or simultaneous-operation multi control of a single system.
• When using central control for multiple systems, a maximum of 30 systems (maximum 64
units) can be connected. In the case of group control or central control, set the system address
to a setting other than 0 (1 or above).
• If the number of systems is greater than 9, this switch can be used in combination with DIP
switch S003 to set up to 30 systems. The setting can be made as high as 39, however all
settings above 30 are handled as 30 for control. (For details, refer to Table 4-1.)
• If system addresses are duplicated (the same address exists more than once), LED 1 on the
outdoor unit control PCB lights up, and alarm "L04" is displayed on the remote controller.
DIP switch (2P, blue): System address 10s-digit and 20s-digit place setting switch
S003
• When setting 10 systems or more, set this switch in combination with S002.
• For 10 – 19 systems, set 1P (10s-digit place) to ON.
• For 20 – 29 systems, set 2P (20s-digit place) to ON, and set 1P (10s-digit place) to OFF.
• For 30 systems, set both 1P (10s-digit place) and 2P (20s-digit place) to ON.
(For details, refer to Table 4-1.)

• Press this switch to perform refrigerant recovery control using cooling operation.The indoor
(CN048)
unit fan will operate at HIGH and 55 Hz for a maximum of 10 minutes. When refrigerant
recovery is completed, close the valves and press this switch to stop the operation.
