Method of connecting Mente PC in the combination Multi system
The design of the outdoor units separates the air flow compartment from
the mechanical compartment, allowing easy access to serviceable parts
by simply removing the panel.
This design also means that the base plate of the air flow compartment
acts as a drain tray connected to a drain pipe that runs through the
mechanical compartment, so a simple connection of a drain hose to the
base of the unit is all that is required, no need for a separate drain tray to
be installed.
Service maintenance and trouble shooting tasks can be carried out easily
via the wired remote controller, as well as a cooling test operation to
assist commissioning.
The outdoor unit control box is also equipped with a switch to invoke a
'test-run' mode. This function can be used to help detect any installation
errors, indoor/outdoor unit matching errors, EEV and valve operation. A
'pump-down' switch on the PCB allows refrigerant to be recovered with
the compressor protected.
All outdoor unit PCBs are also equipped with a 7-segment digital display
for detailed operation history and fault finding. Operation data is stored
for the 30 minute period preceding a fault occurring and details are
displayed on the 7-segment reading.
