Dip Switches.
In the rear of the controller there is a bank of 6 “Dip” switches.
These allow for certain functions to be enabled or disabled.
1) Header/Follower, this allows for more than one remote controller to be connected to a system.
(Default setting OFF – Header)
2) LCD Back Light, this turns ON/OFF the back-light display. (Default setting OFF, Light ON).
3) Temp. Set, this allows for the temperature to be displayed /selected as a whole or a decimal i.e.
21oC Dip switch ON, 21.5oC Dip switch OFF. (Default setting OFF 0.5oC).
4) Remote Sensor, this will set the “Return Air – TA” at the remote controller, (Default is OFF – Return Air –
TA at the indoor unit.)
5) Press and Hold 4 Sec. This will change the operation mode of the ON/OFF switch, the button will
need to be pressed and held for 4 seconds or more to turn ON/OFF the system. (Default OFF – No delay.)
6) Reduces the brightness of the operation indicator lamp of the remote controller, set the lamp to be
dim when the switch is turned on and bright when the switch is turned off. (Default OFF – Bright)

For “DN Code” access.
The RBC-ASCU11-E remote can also be used by service/installation engineers to access the configuration
menu, “DN Codes”
With power applied but the system OFF,
i.e. the power light is NOT illuminated.
Press and hold for 10 seconds the “Menu”
button and the “Down button”
Once the display changes then press the
“Timer” button.
The system automatically starts at “DN Code” 10.
Scroll through the “DN Codes” using the
“Up/Down” buttons.
To move to “Data” (Bottom left display)
press the “Menu” button.
To change the “Data” use the “Up/Down” buttons.
To “Fix” a change to the “Data” press the
“Timer” button.
To end press the “Power Button”
NOTE.
The new “UP” range of VRF indoor units and the new “U” series outdoor units (SMMSu)
utilize a range of new “DN” codes, some of which are now three-digit codes, when
accessing a three-digit code the last digit is slightly smaller than digits one and two.
DN Code 103 (3 figure)
DN Code 03 (2 figure)

Some useful DN codes.
For a full list of “DN Codes” please refer to the service manual for the installed equipment or to one of the
”CDL Pocket Handbooks”
