Data Communication; Override - Danfoss AK-CC55 User Manual

User Guide | Controller for appliance control, AK-CC55

Data communication

The controller has built-in MODBUS data communication.
If there is a requirement for a different form of data
communication, a Lon RS 485 module can be inserted in the
controller.
The connection must then be to the module.
(This option is not available in the compact version).
Display
The controller has one or two plugs for an external display. One of
the following display types can be connected to a plug:
• AK-UI55 Info (temperature display)
• AK-UI55 Set (temperature display and operation)
• AK-UI55 Bluetooth (temperature display and app operation).
The connection between the display and the controller must be
made using an AK-UI55 cable.
The distance between the controller and the display must not
exceed 100 m.
If there are two external displays, it will be the sum of the two
distances that cannot exceed 100 m.
