Wall Control

ActronAir offers NEO and LC7-2, wall controls that can control the available features and maximise the function and 
operation of the air conditioner. To do this, 

CtrS

 on the Outdoor Board has to be set to 

Ct. 1

.

Basic BMS

The unit can be connected to a network through a BMS card (ICUNO-MOD). This allows the unit to be operated in the 
same way the as the NEO and LC7-2 does. To do this, 

CtrS

 on the Outdoor Board has to be set to 

Ct. 2

.

Wall C Basic BMS

The unit can be connected to a network (Basic BMS) and at the same time be controlled using the NEO or LC7-2 control. 
Priority will be given to the most recent command. To do this, 

CtrS

 on the Outdoor Board has to be set to 

Ct. 3

.

Advanced BMS

The unit can be connected for system that requires customised functions not included in the existing software or logic in 
the Outdoor Board but still retaining the safety logic. To do this, 

CtrS

 on the Outdoor Board has to be set to 

Ct. 4

.

15.04.  Configuring Indoor Fan Setting (iduS)

The fan settings may be configured using Three options: the Condenser CPU Board, NEO or LC7-2 Wall Control and Third 
Party Control.

15.04.01.  Indoor Fan Speed Commissioning

The Variable Capacity Commercial indoor fan operation is supplied as a single speed system, with speed settings 
model dependent.  This speed is adjustable via outdoor board and the NEO or LC7-2 wall control (when connected). 
Refer to the fan curve and the fan table section of each models fan speed setting.

When the NEO or LC7-2 Wall Control is connected, the option of a 3-speed indoor fan is available to be programmed. 
The default speed settings for each of the three speeds (High, Medium and Low) are also shown in the table below. 
See Option 2: via Outdoor Board. For more details  see Option 1: via Wall Control (NEO or LC7-2). 

NOTES

ActronAir do not recommend adjusting the RPM limit. Before making any changes, please contact ActronAir Technical 
Support on 1800 119 229.
