ELSTAT SEQUENCE OF OPERATION
Once the cabinet is plugged in, the ELSTAT control will ash "888" and then
go through a parameter check. Once completed, the control will do a "soft
start". Lights come on rst, approximately 30 seconds later the compressor
will start. Approximately 30 seconds from the compressor start up, the evap
motor will start. The control will display "Use". The control will then cycle
the compressor on and o at the predetermined temp (Model specic).
The whole time the controller is on it is learning the customer trac. Once
enough data has been accumulated the controller will now cycle between
two modes. "Standby" and "Use". In the standby mode the controller
predicts that customer trac is nonexistent. It will display (---). It cycles the
compressor to hold about 50˚F. It shuts the lights o and cycles the evap
fan motor. It will hold this pattern until roughly 2 hours before customer
trac is predicted to start. The controller will then switch into the "use"
mode. Cycling the compressor on and o based on temperature (Approx
36˚F to 38˚F product temp). Running lights continuously. The controller will
then cycle between these two modes.
