AK-CC55 Multi Coil

Applications

The chapter outlines application examples:
• 1-3: Control of one, two and three evaporators
• 4: Control of high temperature cold rooms with two evaporators
• 5: Control of low temperature cold rooms with two evaporators
An application setting will configure inputs and outputs so that the controller's operation interface is reflecting the
selected application.

AK-CC55 Multi Coil is optimised for control of one to three expansion valve + different combinations of light, rail
heat and alarm relays. It has 7 Digital Outputs (DO), known as DO1 – DO7, one Analogue Output (AO), known as
AO1, 6 Analogue Inputs (AI), known as AI1 – AI6, an input that can be used as either DI1 (Digital Input) or AI7 (Sensor
Input), and 2 Digital Inputs, known as DI2 - DI3.
Table 7: The controller covers the following five applications:
Application 1-3 Control of one, two and three evaporators.
Application 4 Control of high temperature cold rooms with two evaporators.
Application 5 Control of low temperature cold rooms with two evaporators.
