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.
