About the CK75 Cold Storage Model Heater

CK75 Cold Storage (CS) models come equipped with touch screen and scan

the ambient temperature drops below the Heater Enable Temperature, the system
starts a Heater enabled delay timer.
Once the Heater enabled delay timer expires, the system operates in one of two

on once the following conditions are met in the order listed:

2. The Heater enabled delay timer expires. A snowflake
3. The computer detects a quick rise in the ambient temperature indicating an exit
If you remove the computer from cold storage before the Heater enabled delay
timer expires, the system does not turn on the heater, saving battery power.
Note: When the heaters turn on in Automatic Mode, the icon changes from a
snowflake
In Automatic mode, cold storage battery life may exceed 6 hours (scanning a bar
code every ten seconds). Window defrost times should be a minute or less with
factory default settings implemented.
You can configure the heater operation for your individual environment in
Enterprise Settings or by editing the computer registry values. To learn more, see
