To continue the configuration of the system, it is required to give
some input to the PCB of the unit. This chapter will describe how
manual input is possible by operating the pushbuttons/DIP switches
on the PCB and reading the feedback from the LEDs.
INFORMATION
If you get confused in the middle of the process, push BS1.
Then it returns to setting mode 1 (H1P is off).
6.2.2 Field setting components
The components to make field settings are as follows:
BS2

H7P
MODE
TEST:
L.N.O.P. DEMAND

H1P H2P H3P H4P H5P H6P H8P
BS1~BS5 Pushbuttons
H1P~H8P LEDs

) OFF ( ) Flashing ( )
Pushbuttons
Use the pushbuttons to make the field settings.
BS1 MODE: For changing the set mode
BS2 SET: For field setting
BS3 RETURN: For field setting
BS4 Not used
BS5 Not used
LEDs
The LEDs give feedback about the field settings, which are defined
as [Mode-Setting]=Value.
H1P Shows the mode
H2P~H7P Shows the settings and values, represented in binary code
H8P NOT used for field settings, but used during initialisation
Example:
H1P H2P H3P H4P H5P H6P H7P
- + + + + + [
H1P
32 16 8 4 2 1]
Description
(H1P OFF)
Default situation
(H1P flashing)
Mode 1
(H1P ON)
Mode 2
+ + + + + 0 0 8 0 0 0
(H2P~H7P = binary 8)
Setting 8
(in mode 2)
+ + + + + 0 0 0 4 0 0
(H2P~H7P = binary 4)
Value 4
(in mode 2)
6.2.3 To access the field setting components
Remove the inspection cover to carry out field settings.
b
a
Operate the switches and pushbuttons with an insulated stick (such
as a closed ball-point pen) to avoid touching of live parts.
Make sure to re-attach the inspection cover into the electrical
component box cover after the job is finished.
NOTICE
Make sure that all outside panels, except for the service
cover on the electrical component box, are closed while
working.
Close the lid of the electrical component box firmly before
turning on the power.
6.2.4 To access mode 1 or 2
After the units are turned ON, the display goes to its default
situation. From there, you can access mode 1 and mode 2.
Initialisation: default situation
NOTICE
Be sure to turn on the power 6 hours before operation in
order to have power running to the crankcase heater and
to protect the compressor.
Turn on the power supply of the outdoor unit, and turn on the
external operation switch. After initialisation, the display indication
state will be as below (default situation when shipped from factory).
Single unit
Multi-unit Left unit (master)
Right unit (slave)
If the default situation is not displayed after 10~12 minutes, check
the malfunction code. Solve the malfunction code accordingly.
The HAP LED flashes to indicate normal microcomputer operation.
Switching between modes
Use BS1 to switch between the default situation, mode 1 and
mode 2.

INFORMATION
If you get confused in the middle of the process, press BS1
to return to the default situation.
6.2.5 To use mode 1
Mode 1 is used to monitor the status of the unit.
