12.17 How to Commission Single Component
Context
● On the diagnostic mode screen, you can turn on or
o components, and
control their output ratio.
● If you need to manually turn on or
o system components in diagnostic
mode, ensure that the smart cooling product is started before operation.
● Take commissioning the indoor fan as an example.
Procedure
Step 1 Choose Maint > Diagnostic Mode > Enter.
The screen for entering the diagnostic mode:
● Components are interlocked. Therefore, buttons for turning on or o certain
components are in gray, indicating that operations of the components are not allowed.
● To ensure system security, a component may not promptly respond to operations
performed on this screen. For example, the compressor does not respond promptly after
the O (On) button is tapped if the shortest running (shutdown) time is not met.
● To exit the diagnostic mode, tap
on the status bar.
● The system automatically exits diagnostic mode when it reaches the maximum
diagnostic mode duration.
Step 2 Set Indoor fan to 50%.
For safe system operation, when smart cooling product components are turned on,
the following coupling relationships are presented:
● When the electric heater is turned on, the indoor fans will turn on
automatically.
● When the electrode
humidier is turned on, the indoor fans and inlet water
solenoid valve will start automatically.
● When the input value of the indoor fan is less than the minimum speed, the
indoor fan will run at the minimum speed.
Step 3 Check that the indoor fans run properly, and no alarm generates.
Step 4 Choose Maint > Diagnostic Mode > Exit or tap to exit the diagnostic mode.
