▪ A display to read feedback from the PCB
Field settings are defined by their mode, setting and value. Example:
[2‑1]=2.
PC configurator
It is alternatively possible to make several commissioning field
settings through a personal computer interface (for this, option
EKPCCAB is required). The installer can prepare the configuration
(off-site) on PC and afterwards upload the configuration to the
system.
See also: "6.1.9 To connect the PC configurator to the outdoor
unit" on page 25 .
Mode 1 and 2
Mode Description
Mode 1
(monitoring
settings)
Mode 1 can be used to monitor the current
situation of the outdoor unit. Some field setting
contents can be monitored as well.
Mode 2
(field settings)
Mode 2 is used to change the field settings of
the system. Consulting the current field setting
value and changing the current field setting
value is possible.
In general, normal operation can be resumed
without special intervention after changing field
settings.
Some field settings are used for special
operation. In such a case, it is required to abort
the special operation before normal operation
can restart. It will be indicated in below
explanations.
