When turning on the power supply, the display flashes on and off. First 
checks of the power supply are executed (1 – 2 minutes).

When no trouble occurs: lighted as indicated (8 – 10 minutes).

Ready for operation: blank display indication as indicated.

When above situation cannot be confirmed after 12 minutes, the mal

-

function code can be checked on the indoor unit user interface and the 
outdoor unit segment display. Solve the malfunction code accordingly. 

The communication wiring should be checked at first.

 INFORMATION

Be sure to turn the power on at least 6 hours before operation in order 
to have power running to the crank case heater.

Accessing modes

BS1 is used to change the mode you want to access.

• 

Access mode 1
Push BS1 one time. Segment indication changes to:

• 

Access mode 2
Push BS1 for at least 5 seconds. Segment indication changes to:

 INFORMATION

If you get confused in the middle of the process, push BS1.
Then it returns to idle situation (no indication on segment displays: 
blank, refer to Functions of the push button switches which are located 

on the outdoor printed circuit board (A1P) on page 24).

Mode 1

Mode 1 is used to set basic settings and to monitor the status of the 

unit (15.2. Monitoring function and field settings on page 33).

• 

Changing and access the setting in mode 1:
Once mode 1 is selected (push BS1 one time), you can select the 
wanted setting. It is done by pushing BS2. Accessing the selected 
setting’s value is done by pushing BS3 one time.

• 

To quit and return to the initial status, press BS1.

Example

:

Checking the content of parameter [1-10] (to know how many indoor 
units are connected to the system).

[A-B]=C in this case defined as: A=1; B=10; C=the value we want to 

know/monitor:

• 

Make sure the segment indication is displayed in operational default 
mode as shipped from factory.

•  Push BS1 one time; result segment display:

Result: mode 1 is accessed.

•  Push BS2 10 times; result segment display:

Result: mode 1 setting 10 is addressed.

•  Push BS3 one time; the value which is returned (depending on the 

actual field situation), is the amount of indoor units which are con

-

nected to the system.
Result: mode 1 setting 10 is addressed and selected, return value is 
monitored information.

• 

To leave the monitoring function, push BS1 one time, you will return 
to the default situation when shipped from factory.

Mode 2

Mode 2 is used to set field settings of the outdoor unit and system.

• 

Changing and access the setting in mode 2:
Once mode 2 is selected (push BS1 for more than 5 seconds), you 
can select the wanted setting. It is done by pushing BS2.
Accessing the selected setting’s value is done by pushing BS3 one 
time.

• 

To quit and return to the initial status, press BS1.

• 

Changing the value of the selected setting in mode 2:

 

- Once mode 2 is selected (push BS1 for more than 5 seconds) 

you can select the wanted setting. It is done by pushing BS2.

 

- Accessing the selected setting’s value is done by pushing BS3 

one time.

 

- Now BS2 is used to select the required value of the selected 

setting.

 

-

When the required value is selected, you can define the change 

of value by pushing BS3 one time.

 

- Press BS3 again to start operation according to the chosen value.

Example:

Checking the content of parameter [2-18] (to define the high static 

pressure setting of the outdoor unit’s fan).

[A-B]=C in this case defined as: A=2; B=10; C=the value we want to 

know/change

Make sure the segment indication is as during normal operation (de-
fault situation when shipped from factory).

•  Push BS1 for over 5 seconds; result segment display:

Result: mode 2 is accessed.

•  Push BS2 18 times; result segment display:

Result: mode 2 setting 18 is addressed.

•  Push BS3 one time; the value which is returned (depending on the 

actual field situation), is the status of the setting. In the case of [2-

18], default value is 0, which means the function is not active.
Result: mode 2 setting 18 is addressed and selected, return value is 
the current setting situation.

• 

To change the value of the setting, push BS2 till the required value 

appears on the segment indication. When achieved, define the set

-

ting value by pushing BS3 one time. To start operation according to 

the chosen setting, confirm again by pushing BS3.

• 

To leave the monitoring function, push BS1 two times, you will 
return to the default situation when shipped from factory.
