RE-LEARNING
If the outlet’s business times change or the learnt pattern is incorrect then the EMS will automatically
relearn. Under these circumstances the original pattern will be erased and the learning process will
begin again from day 1. Please note that the activity frequency will not be recalculated during a
relearn. For a relearn to occur the EMS must detect movement or the door being opened during a
stand by period. (The EMS can only relearn if it has finished learning).
ERASING THE EMS MEMORY
Half factory reset
If required, the learnt pattern can manually be erased by the using the following procedure:
Defrost button used to
erase the matrix
Disconnect the power to the control (unplug the cooler), push and hold the defrost button and restore
the power. Keep the button pressed until the display shows the temperature again, release the button
and the matrix will be erased. The control will then start to relearn. (During this procedure there will be
a short period when the display is blank)
Full factory reset
A full factory reset will erase the matrix, reset all parameters to the default and reset all the statistics
including the compressor running hours.
