Description
This function is automatically
started during maintenance. Based
on the system pressure change,
this function recycles all or partial
refrigerant of the faulty module or
the indoor unit pipeline.
The unit can be set to cooling and
heating, cooling only, heating only,
or fan mode for centralized
management.
This function sets different silence
modes based on the user's needs.
During maintenance, the system
automatically turns on all electronic
expansion valves and solenoid
valves to ensure that all lines can
be vacuumed.
This function can automatically
reduce power consumption of the
unit based on system operating
parameters.
This function forcibly enables
defrosting of the outdoor unit of the
system.
This function forcibly reduces the
maximum power consumption of
the unit.
When different refrigerating
systems are controlled in a
centralized manner, this function
avoids the conflict of indoor unit
engineering numbers.
This function opens the water
valves of all dual-heat-source
indoor units in the system.
