The controller automatically cycles between three primary states to balance product temperature with energy savings:
Re-enter the password sequence to confirm. This clears the 7-day learning memory but keeps the compressor run-time data.
Initiates a manual defrost cycle or exits the current menu level. Technical Data Input Voltage: 100–240 VAC, 50/60 Hz
Press and hold the Set (snowflake) button until the display shows "PAS" . Input Sequence: Press Set four times ( x4 ). Press the Up Arrow once ( x1 ). Press the Down Arrow twice ( x2 ). Press the Defrost/Teach button twice ( x2 ). Elstat Ems 25 Advanced Manual
Navigates forward through menu items and increases parameter values.
If you have replaced a compressor or want to clear the "learning" memory, you can perform a ( Hr ): Enter the programming mode (the "key dance" above). Use the Down arrow to scroll until the display shows Hr .
: Displayed during the initial power-up sequence and parameter check. Technical Data Input Voltage: 100–240 VAC, 50/60 Hz
The front panel features a three-digit LED display and four primary control buttons:
100-240VAC (internal power supply converts to 12VDC for the display).
To help clarify your next steps with this energy management system, please let me know: Press the Down Arrow twice ( x2 )
: Increases parameter values during programming. Pressing and holding manually triggers a forced defrost cycle. Down Button : Decreases parameter values during programming. LED Status Indicators
The controller moves through distinct operational modes to balance product temperature with energy conservation. Operational State (Ready Mode)
: Embedded directly into the faceplate to actively detect kinetic movement and ambient heat sources. This helps map store opening and closing periods. 2. Menu Access and Password Authentication
The display will scroll through statistics, pausing for 20 seconds on each:
After adjusting any parameter value using the arrow keys, press to lock in the change. To exit the menu and return to the live temperature display, press the Defrost/Back button or wait 30 seconds for the system to time out automatically. 4. Troubleshooting and Alarms
