Appliance Cleaning - Danfoss AK-CC55 Multi Coil User Manual

AK-CC55 Multi Coil
The three sensor points must be:
1. Lowest temperature in wanted measuring range
2. Highest temperature value in wanted temperature range
3. Temp. value in the middle where a high measuring accuracy is required
A sensor error is detected at temperature values below/above the min./max. temperature values typed in for the
sensor points.

Limitations:
A user defined temperature sensor can only be be defined within the temperature range from -40 – +60 °C and
within the resistance range from 400 – 179.999 ohm.
When applying a new user defined sensor type, please contact Danfoss for validation of compliance and measuring
accuracy.

Appliance cleaning

This function makes it easy for the shop's staff to carry out a cleaning of the appliance according to a standard
procedure. Appliance cleaning is activated via a pulse signal – as a rule via a key switch placed on the appliance or
via the AK-CC55 Connect mobile app.
Appliance cleaning is carried out via three phases:
1. At the first activation, the refrigeration is stopped, but the fans keep on operating in order to defrost the
evaporators. "Fan" is shown on the display.
2. At the second activation, the fans are also stopped and the appliance can now be cleaned. "OFF" is shown on the
display.
3. At the third activation, refrigeration is recommenced. The display will show the actual appliance temperature,
o97 setting.
When appliance cleaning is activated, a cleaning alarm is transmitted to the normal alarm recipient. A later
processing of these alarms will document that the appliance has been cleaned as often as planned.
There are no temperature alarms during appliance cleaning.
