True Manufacturing Company GDM-26 Manuel D’Utilisation

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.
