Note: ems controllers must be able to detect activity to work correctly. The motion detector should never be obstructed.
The diagram below shows the detection pattern of the motion sensor.
ems controllers use activity to determine when retail outlets are open and closed. Periods with activity mean the retail out-
let is open, and periods without activity mean the retail outlet is closed.
ems controllers run coolers in the ready mode during periods with activity and the saving mode during periods without activ-
ity.
ems controllers record the periods with and without activity in the self-learning matrix.

ready mode
ems controllers run in the ready mode when outlets are open.
In the ready mode, the product is at the correct serving temperature and the cooler lights are on.
ems controllers ensure that the product is at the correct serving temperature by keeping the product temperature within
the range defined by set point (S P) parameter and the differential (dI F) parameter.
The ems controller runs the compressor until the set point (S P) temperature is reached. The compressor is then stopped
until the measured temperature reaches the set point (S P) plus differential (dI F) temperature.
