This is a structured Content Outline for the ELSTAT EMS 55 Advanced User Manual (New Edition). This outline assumes the device is an advanced energy management system, power analyzer, or grid monitoring unit (common for the "EMS 55" series in industrial settings).
7. Safety & Compliance (New Edition Notes)
- Overvoltage category: CAT III (600V L-L max)
- Installation: Use only UL/CSA-listed fuses (max 10A) on voltage inputs.
- New compliance mark: CE-RED (for wireless M-Bus variants) and UKCA.
- Firmware upgrade: Now possible via IR port using ELSTAT “Loader Tool v2.0” (manual includes CRC verification steps).
3. Wiring and Installation
The Advanced Manual dedicates a significant section to wiring diagrams, which is critical for the "New" hardware revisions.
- Terminal Layout: The manual outlines the specific terminal blocks for:
- Power supply (Typically 230V AC or 24V versions).
- Compressor output (relay rating).
- Defrost output.
- Fan output.
- Auxiliary outputs (Lights, Heat traced drain lines).
- Sensor Inputs:
- S1 (Evaporator Probe): Usually located on the evaporator coil to terminate defrost.
- S2 (Product Probe): Located in the air or product to control the compressor based on load temperature.
- S3 (Optional): Often used for condenser monitoring or a second product probe.
- Safety Note: The manual emphasizes that wiring must be performed by qualified personnel and usually includes specific instructions regarding the separation of high and low voltage cables to prevent interference.
7. Important Notes
- Safety First: Changing parameters like C2 (Output Delay) or dF (Defrost Type) without understanding them can damage the compressor or cooling coils.
- Lock-out: On newer versions, if you hold buttons incorrectly, the unit may lock. Wait 60 seconds and try again.
- Sensors: The EMS 55 usually relies on two sensors (Evaporator and Ambient/Cabinet). If defrost is not working correctly, check the evaporator sensor first.
Note: This guide covers the standard Elstat EMS 55 firmware. Some OEMs (like Coca-Cola) may have custom firmware where parameter codes differ slightly (e.g., using P1, P2 instead of C1, C2).

The Elstat EMS 55 Advanced is an intelligent energy management controller designed for commercial refrigeration. It uses self-learning technology to predict store opening times and adjust cooling modes to save energy during closing hours. 1. Key Operating Modes
The controller automatically cycles between three primary states based on a learned 7-day schedule:
Active Mode (USE): The cooler is ready for customer use. Lights are on, and the product is maintained at the optimal serving temperature (e.g., 36°F–38°F).
Standby Mode (---): Occurs during closing hours. Lights are off, the evaporator fan cycles, and the temperature is allowed to rise to a more economical set point (approx. 50°F) to save power.
Defrost Mode (dEF): The compressor stops while the evaporator fan runs to clear ice buildup. This is a pre-programmed maintenance function. 2. Accessing the Configuration Menu
To change settings or perform resets, you must enter the "key dance" password sequence: Press and hold SET until PAS appears on the display. Enter Password Sequence: Press SET (Snowflake) 3 times. Press UP arrow 2 times. Press DOWN arrow 1 time. Press DEFROST (Water drops) 4 times.
The display should now show PS, confirming you are in the parameter menu. 3. Common Settings & Resets
Half Reset (Hr): Clears the self-learning matrix so the controller can re-learn a new business schedule. Navigate to Hr in the menu and enter the password sequence again to reboot.
Perishable Mode: If enabled (setting 1), the unit will not enter standby mode, maintaining a constant low temperature to protect high-risk food items.
Test Routine (tst): Used by technicians to verify that the compressor, lights, and fans are functioning correctly. 4. Troubleshooting Display Codes 888 Initial Power-up Normal startup sequence. USE Ready Mode System is operating normally for customers. --- Standby Mode System is in energy-saving mode. PF1 / PF2 Probe Failure
Check connections for appliance (1) or condenser (2) sensors. dEF Defrosting Normal cycle; wait for it to complete.

The Elstat EMS 55 Advanced is a sophisticated energy management system designed specifically for commercial refrigeration. It utilizes "self-learning" algorithms to balance energy savings with product temperature integrity.
The following comprehensive overview serves as a detailed guide to the unit’s operation, parameter logic, and maintenance. 🟢 System Overview
The EMS 55 is an intelligent controller that replaces standard thermostats. It learns the usage patterns of a retail environment to determine when a cooler should be in "Ready Mode" (active cooling) or "Saving Mode" (energy conservation). Self-Learning Logic: Monitors door openings and motion. Energy Savings: Can reduce consumption by up to 35%.
Dual Sensors: Uses an appliance sensor (air temp) and a condenser sensor (safety). 🛠 Operation Modes 1. Ready Mode This is the standard operating state during business hours. The controller maintains the set-point temperature. The lights remain ON. The fan cycles normally to ensure even cooling. 2. Saving Mode
Activated when the unit detects the store is closed or inactive.
The set-point temperature is allowed to rise slightly (Save Set Point). The lights are turned OFF to save power. The compressor runs less frequently. 3. Freeze-Up Protection
If the evaporator temperature drops too low, the EMS 55 enters a protection cycle. It shuts down the compressor while keeping the fans running to melt ice buildup. 📋 Advanced Parameter Settings
To access the advanced menu, users typically hold the Function Button for five seconds. Key parameters include: Description SP The target temperature for Ready Mode. SSP Saving Set Point The target temperature during Saving Mode. DIF Differential
The allowable temperature swing before the compressor kicks in. DFT Defrost Time The duration of the timed defrost cycle. LST Low Storage Temp
The absolute minimum temperature allowed to prevent freezing. PST Pull Down Time
Maximum time allowed to reach the set point before an alarm sounds. ⚠️ Alarm Codes & Troubleshooting
The EMS 55 communicates issues through three-letter codes on the LED display:
PF1: Appliance Sensor Failure. The unit will run on a timed cycle to protect stock.
PF2: Condenser Sensor Failure. Check for disconnected wires at the back.
HT: High Temperature. Likely caused by a blocked condenser or a door left open.
CL: Condenser Clean. A reminder that the cooling fins are dusty and restricting airflow.
dF: Defrost in progress. This is a normal functional state, not an error. 🧼 Maintenance Best Practices
Clean the Condenser: Use a soft brush or vacuum every 3 months. High "HT" or "CL" alarms are usually solved here.
Check Door Seals: The EMS 55 learns based on door activity. If seals are leaky, the unit may struggle to enter Saving Mode.
Sensor Placement: Ensure the appliance sensor is not touching the evaporator coils, as this will give false "cold" readings.
To help you get the most out of your controller, please let me know: Are you seeing a specific error code on the display? Do you need help adjusting the temperature set points? Are you trying to force a manual defrost?
I can provide the specific button-press sequences for any of these tasks!

1. Introduction
The ELSTAT EMS 55 is a high-precision electronic energy meter used for submetering, energy management systems (EMS), and cost allocation in commercial and industrial facilities. The “New” Advanced User Manual reflects updated firmware (v3.x or higher), enhanced communication protocols (Modbus RTU/TCP, M-Bus, and optional LON), and improved data logging capabilities.
This write-up consolidates the advanced features, programming procedures, diagnostics, and integration methods for technical personnel, energy managers, and system integrators.
Issue 1: "Err1" or "Err2" on Display
- Meaning: Probe 1 or 2 is open circuit or shorted.
- Advanced fix: Do not just replace the probe. First, use a multimeter to check resistance: Pt100 should read 100Ω at 0°C. If resistance is correct, check the RJ12 connector for cold solder joints (a known issue in high-humidity environments).
