– with USB port or Bluetooth
– with BEST Software installed
The BEST Software can be downloaded for free
from the BITZER website (www.bitzer.de).
• Data connection
– via BEST interface converter
– or via Bluetooth 4.0. Range approx. 3 m
• If the BEST interface converter is used, the com-
pressor must be controlled via the analogue connec-
tion (CN13). The Modbus connection does not allow
capacity control and BEST data connection at the
same time. Bluetooth is not available upon market
launch.
Setting up communication
• Only for communication via the BEST interface con-
verter: Plug the cable into the compressor control
module (CN14) and the mobile device.
• Switch on the mobile device and start the BEST
Software.
A window displaying the available devices opens.
• Select CM-RC-01.
• Click the C
ONNECT
button.
• Only for communication via Bluetooth: Enter the au-
thorization code.
The C
ONFIGURATION
menu appears with the M
AIN
S
ETUP
window. This concludes the connection of the com-
pressor control module to the mobile device.

Configuring CM-RC-01 with the BEST Software
In its state of delivery, the compressor control module
CM-RC-01 is configured for the compressor, in which it
is built in, and its motor. Date and time should be
checked and adjusted if necessary. Afterwards, a con-
figuration of the installed options is required. Depend-
ing on the system design, it may be useful to adjust
some other parameters.
8.2.1
Setting the current time
Check the programmed date and time using the BEST
Software:
• Check the C
ONFIGURATION
menu, the M
AIN
S
ETUP
win-
dow and the D
ATE
and T
IME
lines.
• Correct the data if necessary.
8.2.2
Checking the motor start function
The compressor control module controls the activation
and deactivation times of the motor contactors. In the
state of delivery, the time relay control is configured for
the installed motor. The BEST Software can be used to
check and change the configured motor start method
(part winding, star-delta or direct-on-line start).
Check in the BEST Software and adapt if necessary:
• C

UNCTION
win-
dow. When operating with frequency inverter or soft
starter, the system must be set to direct-on-line start.
If necessary, set the suitable motor start function.
In any case, the compressor motor is activated
1 second after the release signal of the superior system
controller.
8.2.3
Activating application limits monitoring
◦ Requirements: High pressure and low pressure
transmitters are installed.
• Set the refrigerant in the BEST Software: select the
refrigerant used in the R

window in the
M

menu.
• Enter relative pressure limit values that are adapted
to the system in the C

Data log
All monitored operating parameters and alarm mes-
sages are stored internally:
• All operating parameters in 10-second intervals of at
least the last 14 days
• The last 10 faults in detail
• Statistics for the last 365 days
The data can be exported as files using the BEST Soft-
ware. They enable an analysis of the system operation
and detailed error diagnostics if necessary.
