Installation in network

1. Set the address (here, for example 3)
Turn the right-hand address switch so that the arrow will point
at 3.
The arrow of the two other address switches must point at 0.
2. Push the Service Pin
Press down the service pin and keep it down until the Service
Pin LED lights up.
3. Wait for answer from the system unit
Depending on the size of the network it may be up to one
minute before the controller receives an answer as to whether
it has been installed in the network.
When it has been installed the Status LED will start to flash
faster than normal (once every half second). It will continue
with this for about 10 minutes
4. Carry out new login via Service Tool
If the Service Tool was connected to the controller while you
installed it in the network, you must carry out a new login to
the controller via the Service Tool.

The controller has to be remote-monitored via a network. In this net-
work we assign address number 3 to the controller.
The same address must not be used by more than one controller in the
same network.
Requirement to the system unit
The system unit must be a gateway type AKA 245 with software version
6.0 or higher. It is capable of handling up to 119 AK controllers.
Alternatively, it can be an AK-SM 720. It is capable of handling up to 200
AK controllers.
If there is no answer from the system unit
If the Status LED does not start flashing faster than normal, the control-
ler has not been installed in the network. The reason for this may be
one of the following:
The controller has been assigned an address out of range
Address 0 cannot be used.
If the system unit in the network is an AKA 243B Gateway only the ad-
dresses between 1 and 10 can be used.
The selected address is already being used by another controller or
unit in the network:
The address setting must be changed to another (vacant) address.
The wiring has not been carried out correctly.
The termination has not been carried out correctly.
The data communication requirements are described in the document:
"Data communication connections to ADAP-KOOL® Refrigeration Con-
trols" RC8AC.
