ems controllers functionality

ems controllers have the capability to manage the following:
temperature: ems controllers measure the air temperature of the refrigeration compartment to control the temperature of the products.
l
ems controllers ensure that products are at the optimal serving temperature.
condenser: ems controllers manage the temperature on the condenser to prevent high temperature.
l
This is optional for ems controllers, and dependent on controller specification.
compressor: ems controllers switch the compressor to manage the performance of the compressor.
l
evaporator fan:ems controllers switch the evaporator fan to manage the temperature of the refrigeration compartment.
l
This is optional for ems controllers, and dependent on controller specification.
lights: ems controllers manage the cooler lights for marketing and energy saving purposes.
l
Note:
Dependent on controller and sensor configuration.

product temperature

ems controllers manage the product temperature.
ems controllers use an appliance sensor to measure the air temperature of the refrigeration compartment.
The location of the appliance sensor within the refrigeration compartment depends on the cooler type.
However, to compensate for differences between the air temperature and the product temperature, calibration 1 (C A1) can
add an offset to the temperature measured on the appliance sensor.
See "calibration 1 (CA1)" on page 69
l
ems controllers can be set to use Celsius (°C) or Fahrenheit (°F) - set by the Celsius or Fahrenheit (C F) parameter.
See "Celsius or Fahrenheit (CF)" on page 70

activity

ems controllers learn when retail outlets are open or closed by monitoring activity. For example, people opening and closing
the cooler door to retrieve products or movements detected in front of the cooler.
ems controllers detect activity as follows:
