5. 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. ems controllers ensure that products are at the optimal
serving temperature.
• Condenser: ems controllers manage the temperature on the
condenser to prevent high temperature. This is optional for ems
controllers, and dependent on controller specification.
• Compressor: ems controllers switch the compressor to manage
the performance of the compressor. evaporator fan:ems controllers
switch the evaporator fan to manage the temperature of the
refrigeration compartment. This is optional for ems controllers, and
dependent on controller specification.
• Lights: ems controllers manage the cooler lights for marketing and energy saving purposes.
Note
Dependent on controller and sensor configuration
5.1 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 (CA1) can add
an offset to the temperature measured on the appliance sensor.
ems controllers can be set to use Celsius (°C) or Fahrenheit (°F) - set by the Celsius or Fahrenheit (CF) parameter.
