The Elstat EMS 55 Advanced is a self-learning energy management controller designed for commercial refrigeration units like glass door coolers (GDC). It utilizes a "7-day learning matrix" to automatically detect business hours via motion sensors and door openings, switching between high-efficiency "Standby" and standard "Ready" modes to save up to 38% in energy costs. Key Technical Specifications

The EMS 55 Advanced is engineered for precision and durability in demanding commercial environments: Operating Voltage: 12V AC (<15W SELV). Temperature Range: Monitors appliance temperatures from and condenser temperatures from Display: 15mm 7-segment green LED.

Sensors: Uses NTC thermistors and a Passive Infrared (PIR) motion detector. IP Rating: Front panel rated IP45; Rear rated IP24. Accessing the Advanced Menu (The "Key Dance")

To modify parameters or perform resets, users must enter a specific button sequence known as the "key dance" to unlock the menu:

Enter Password Mode: Press and hold the SET (snowflake) button until PAS appears. Input Sequence: Press SET 3 times. Press UP 2 times. Press DOWN 1 time. Press DEFROST (water drops) 4 times. Confirm: The display should show PS. Reset Procedures There are two main types of resets for the EMS 55 Advanced: ems-55-controller.pdf

Elstat EMS 55 Advanced is an intelligent energy management system designed to reduce electricity consumption in commercial refrigeration by learning foot traffic patterns and adjusting cooling modes accordingly. By utilizing motion sensors and door switches, it transitions the chiller into energy-saving modes during low-activity periods. combustioncontrols.pk Core Operational Modes elstat ems 55 advanced user manual new

The controller cycles through three primary states based on detected activity: Active Mode (

The standard operating state where product is kept at the set temperature and cabinet lights are on. Standby Mode (

Activated during periods of inactivity (e.g., after business hours). The lights turn off, and the temperature is allowed to rise slightly to save energy. Defrost Mode (

A predetermined program function where the compressor shuts off and the fan runs to clear ice buildup. combustioncontrols.pk System Programming & Reset

Advanced users can access specific menus to clear learning memory or test components using a specific "key dance" sequence: Accessing the Menu: Press and hold the (snowflake) button until (password) appears on the display. The "Key Dance" Password: (snowflake) (water drops) Memory Reset (Half Reset): Once in the menu, scroll to (Half Reset) and press to clear the learning matrix. Coca-Cola Parts Common Troubleshooting Codes If the system encounters an issue, it will display specific error codes

Appliance or condenser sensor failure. Check sensor connections.

Door is open. Ensure the door is fully closed or check the door switch.

High temperature alarm. This often indicates a blocked condenser or inadequate ventilation.

The Elstat EMS 55 Advanced is an energy management controller that uses a self-learning algorithm to optimize refrigeration cooling based on customer traffic patterns. It automatically switches between Active (Ready) and Standby modes to reduce energy consumption during periods of low activity. 1. Operational Modes & Display Codes

The controller identifies and adapts to usage cycles via motion sensors and door switches.

"888" (Startup): Displayed immediately upon power-up during a parameter check.

"USE" (Active Mode): The chiller is in normal operation, maintaining set product temperatures (typically 36°F to 38°F) with lights on. The new EMS 55 has a hidden 3

"---" (Standby Mode): Displayed when no activity is detected. The unit raises the temperature (around 50°F) and turns off lights to save power.

Perishable Mode: If enabled, the unit bypasses Standby mode to maintain consistent cooling for sensitive products. 2. Advanced Menu Access (The "Key Dance")

To modify parameters or perform resets, you must enter a specific password sequence known as the "key dance".

Press and hold the Set (Snowflake) button until "PAS" appears. Follow this specific button sequence: Set (Snowflake): Press 3 times. Up Arrow: Press 2 times. Down Arrow: Press 1 time. Defrost (Water Drops): Press 4 times.

The display should now show "PS", indicating successful entry into the configuration menu. 3. Reset Procedures

Resetting the device is often necessary to clear an old learning matrix if the cooler is moved to a new location.

Half Reset (Hr): Clears only the self-learning memory (opening/closing schedule).

Access the menu as described above, scroll to "Hr", and press Set to confirm.

Complete Reset: Erases all settings and returns them to factory defaults.

Unplug the unit, hold down Reset and Defrost, and reconnect the power while holding both until "USE" appears. 4. Technical Specifications

For hardware maintenance or replacement, note these key technical ratings: Voltage: 12 Volt AC.

Temperature Range: Appliance sensor operates from -15°C to +23.5°C (+5°F to +74°F). To change fan delays, defrost intervals, or differential

IP Rating: Front panel is IP45 (dust and water jet protected); Rear is IP24.

Relays: Supports compressor relays (up to 30 Amp), evaporator fan relays (4 Amp), and light relays (500W). Go to product viewer dialog for this item.

Elstat Ems-55 Temperature Controller Refrigerator Thermostat

Elstat EMS 55 Advanced represents a significant leap in refrigeration technology, moving beyond simple thermostats to a predictive energy management system. By utilizing self-learning algorithms and multi-sensor inputs, it balances strict temperature regulation with energy savings of up to 38%. Core Functionality and Intelligence The hallmark of the EMS 55 Advanced is its self-learning matrix

. Unlike traditional controllers, it tracks customer traffic patterns via motion sensors and door openings to build a seven-day operational schedule. Coca-Cola Parts Active Mode:

The controller prepares the unit roughly two hours before predicted peak traffic, ensuring product temperature is ideal for sales. Standby Mode:

During periods of inactivity (e.g., after-hours), the system enters an economical state where lights are extinguished and internal temperatures are allowed to rise slightly to save power. combustioncontrols.pk Advanced Features for the Expert User

The "Advanced" manual details several technical capabilities that distinguish this model from its predecessors: Dual Probe Monitoring:

It uses two NTC thermistor sensors—one for the appliance cabinet and one for the evaporator coil—providing much more reliable temperature control than single-probe systems. Perishable vs. Non-Perishable Settings:

Users can toggle between these modes to adjust the strictness of temperature maintenance based on the product type. Protection Systems: It includes built-in safeguards like Freeze-up Protection (to prevent ice accumulation) and Supply Low Alarms (to protect motors during voltage drops). combustioncontrols.pk Technical Access and Troubleshooting
