5.1 DAY AND NIGHT MODE
In DAY mode, the temperature is lower to keep the products inside the cooler at the correct temperature for resale, and
the lights are ON for Point of Sale (POS). In NIGHT mode the regulated temperature is higher than in DAY mode as the
products do not need to be as cold, and the lights are OFF as no need for POS. This saves energy and reduces the work
load of the outputs (compressor) to extend operational life. Switching between day and night mode is controlled by
learning algorithm which makes the decision based on what it learned a week before.
5.2 NORMAL, ECO AND SUPERFROST MODE
In either Day or NIGHT mode there are 3 different temperature cut-in/cut-out settings which can be implemented:
Normal, Eco or Superfrost. The values can be customisable. Normal is the standard cut-in/cut-out temperature required
for general cooler operation. Eco has higher cut-in/cut-out temperature than Normal and Superfrost has lower cut-
in/cut-out temperature vales than Normal. These settings are manually activated by pressing buttons on the display
interface.
5.3 DEFROST MODE
Depending on customer requirement there are different parameters which can trigger the defrost mode:
Defrost can be triggered by either using the temperature of the evaporator probe or/and by time lapse (see defrost in
parameters for different type of timers). When both settings are enabled which ever event happens first will trigger or
end the defrost cycle. The JEA can also be forced into defrost by pressing a button on the display interface.
The JEA has a minimum defrost duration and minimum duration between defrost cycles which must be satisfied before
it will act no matter the status of the other parameters. This is to ensure the defrost cycle is not stopped too early or
defrost cycles are not initiated to close together.

5.4 WINTER MODE
Winter mode is designed for when coolers are in extreme cold temperatures (For example: outdoor coolers in cold
countries such as Russia), and requires a heater to be fitted. The compressor will be turned OFF and the heater will be
turned ON. This is to warm up the inside of the cooler to ensure products in the cooler do not get too cold and freeze.
Winter mode is entered automatically based on configurable parameters.
