ELSTAT
SEQUENCE
OF
OPERATION
Once the cabinet is plugged in, the ELSTAT control will flash "888" and then go through a parameter check. Once completed, the control will do a "soft start". Lights come on first, 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 off at the predetermined temp (Model specific).
The whole time the controller is on it is learning the customer traffic. 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 traffic is nonexistent. It will display (---). It cycles the compressor to hold about 50˚F. It shuts the lights off and cycles the evap fan motor. It will hold this pattern until roughly 2 hours before customer traffic is predicted to start. The controller will then switch into the "use" mode. Cycling the compressor on and off based on temperature (Approx 36˚F to 38˚F product temp). Running lights continuously. The controller will then cycle between these two modes.
