Monitoring function and field settings
The operation of the outdoor unit can further be defined by changing
some field settings. Next to making field settings it is also possible to
confirm the current operation parameters of the unit.
The setting can also be performed via the PC configuration software.
Below relevant Monitoring mode (mode 1) and Field setting mode
(mode 2) settings are explained in detail. How to access them, how to
change the value of the settings and how to confirm them is explained
in 13. Making field settings on page 24. In that chapter, an example
is given on how to make a setting. It is advised to check this procedure
before accessing, checking and changing below settings.
Once the default situation of the segment indication is confirmed (see
13. Making field settings on page 24), the mode 1 and mode 2 can
be accessed.
Making settings is done via the master outdoor unit.
15 .2 .1 . Mode 1
Mode 1 can be used to monitor the current situation of the outdoor
unit. Some field setting contents can be monitored as well.
Below the settings in mode 1 are explained.
[1-0]=
shows whether the unit you are checking is a master or sub
1 unit
• No indication=undefined situation
•
0=outdoor unit is master unit
•
1=outdoor unit is sub 1 unit
Master and sub 1 indications are relevant in multiple outdoor
unit system configurations. The allocation of which outdoor
unit is master and sub 1 are decided by the unit’s logic.
The master unit must be used to input field settings in
mode 2 .
[1-1]=
shows the status of low noise operation.
•
1=unit is currently operating under low noise restrictions
•
0=unit is currently not operating under low noise restric-
tions
Low noise operation reduces the sound generated by the
unit compared to nominal operating conditions.
Low noise operation can be set in mode 2. There are two
methods to activate low noise operation of the outdoor unit
system.
The first method is to enable an automatic low noise opera
-
tion during night time by field setting. The unit will operate at
the selected low noise level during the selected time frames.
The second method is to enable low noise operation based
on an external input. For this operation an optional acces
-
sory is required.
[1-2]=
shows the status of power consumption limitation operation.
•
1=unit is currently operating under power consumption
limitation
•
0=unit is currently not operating under power consump-
tion limitations
Power consumption limitation reduces the power consump-
tion of the unit compared to nominal operating conditions.
Power consumption limitation can be set in mode 2. There
are two methods to activate power consumption limitation of
the outdoor unit system.
The first method is to enable a forced power consumption
limitation by field setting. The unit will always operate at the
selected power consumption limitation.
The second method is to enable power consumption
limitation based on an external input. For this operation an
optional accessory is required.
[1-5]=
shows the current T
e
target parameter position.
Refer to 15.3. Energy saving and optimum operation on
page 37 for more details about the contents of this value.
[1-6]=
shows the current T
c
target parameter position.
Refer to 15.3. Energy saving and optimum operation on
page 37 for more details about the contents of this value.
[1-10]= shows the total number of connected indoor units.
It can be convenient to check if the total number of indoor
units which are installed match the total number of indoor
units which are recognized by the system. In case there is a
mismatch, it is advised to check the communication wiring
path between outdoor and indoor units (F1/F2 communica-
tion line).
[1-13]= shows the total number of connected outdoor units.
It can be convenient to check if the total number of outdoor
units which are installed matches the total number of out-
door units which are recognized by the system. In case there
is a mismatch, it is advised to check the communication
wiring path between outdoor and outdoor units.
[1-17]= shows the latest malfunction code.
[1-18]= shows the 2nd last malfunction code.
[1-19]= shows the 3rd last malfunction code.
When the latest malfunction codes were reset by accident
on an indoor unit user interface, they can be checked again
through this monitoring settings. For the content or reason
behind the malfunction code see 15.5. Malfunction code list
on page 40, where most relevant malfunction codes are
explained. Detailed information about malfunction codes can
be consulted in the service manual of this unit.
[1-40]= shows the current cooling comfort setting. See 15.3. Energy
saving and optimum operation on page 37 for more de
-
tails about this setting.
[1-41]= shows the current heating comfort setting. See 15.3. Energy
saving and optimum operation on page 37 for more de
-
tails about this setting.
