Appliance shutdown
The function closes the AKV valve and all outputs are switched o. The cooling appliance is stopped like the “Main
switch”, but this happens without an “A45 standby alarm”. The function can be enabled by a switch on the DI input
or via a setting through data communication.
Defrost
Depending on the application, you may choose between the following defrost methods:
Natural: Here the fans are kept operating during the defrost
Electric: The heating element is activated
Electrical defrosting
At electrical defrost, an electrical heater is placed in front of the evaporator and the fan will “pull” the hot air through
the evaporator during defrosting.

Natural defrost
At natural defrost, the ice is melted by running the fans and thereby circulating warm air through the evaporator.

Start of defrost
A defrost can be started in dierent ways:
Interval:
Defrost is started at xed time intervals like e.g. every eighth hour. An interval must ALWAYS be set to a "higher"
value than the period set between two defrostings when a schedule or network signal is used.
Week schedule:
Here defrost can be started at xed times of the day and night. However, max. 6 defrosts per day.
Contact:
Defrost is started with a contact signal on a digital input.
