1. CONTROLLER WITH INTELLIGENCE
The Nexo controllers are the first truly intelligent refrigeration
solution for the beverage industry that delivers consumer insights
from field data to optimize and take complete control of cold drink
marketing.
Elstat's game-changing Nexo platform is a powerful tool that
connects drink brands directly to consumers at the point of sale,
wherever they are in the world, to create sustainable and profitable
relationships.
The energy management system controllers from Elstat are used
in a variety of drinks coolers, optimising energy savings, without
compromising on drinks serving temperature.
The CMS200 Nexo controller is designed for sub-zero beer coolers.
It consists of Control Display Module (CDM) and a Power Supply
Module (PSM) connected by an interface cable.
1.1 Control Display Module
The control display module (CDM) consists of the user interface
with a large 3-digit 7-segment LED display, the temperature
sensors and door switch inputs.
CDM is powered by a 12VDC supply from the power supply
module and it provides the following functionality:

3-digit, 7-segment display that displays the product temperature and other information
such as defrost and alarm conditions.
Push buttons enable the end-users to cancel alarms and service technicians to run test
routines.
An appliance sensor measures temperature of the refrigeration compartment. The
controllers use the refrigeration temperature to manage the product temperature.
An optional condenser sensor measures the temperature of the refrigeration system.
The controllers use the temperature to alert to problems such as blocked condensers.
A remote or integrated motion sensor enables controllers to detect activity when
someone moves in front of the cooler.
A door switch enables the controllers to detect cooler activity when someone opens the
cooler doors.
Timed-based or temperature-based defrost can be boosted by a defrost heater or a hot
gas defrost. An evaporator sensor is required for temperature-based defrost.

Questions and answers
Hello! My fridge doesnt cool but it heats, how can i fix the settings?
To fix the cooling settings on your Elstat Nexo CMS200 fridge that heats instead of cools, follow these steps:
1. Check Temperature Settings: Ensure the temperature settings are correctly configured for cooling and not heating.
2. Verify Appliance Sensor: Confirm that the appliance sensor is reading the correct temperature and is properly connected. The controller should register a PF1 alarm if the sensor is disconnected.
3. Inspect Condenser and Fan: Check for any blockages in the condenser grill, ensure the condenser fan is functioning properly, and look for excessive freeze-up in the evaporator.
4. Adjust HT Parameter: Ensure the High Temperature (HT) parameter setting is appropriate for the ambient conditions.
5. Check for Refrigeration System Leaks: Inspect the system for any leaks that may affect cooling performance.
6. Perform a Half Reset: If required, reset the controller by following the half-reset procedure:
- Press the Set button.
- Enter the button sequence for the main menu.
- Press Set four times.
- Press Down twice.
- Press Up once.
- Press Defrost twice.
- Scroll to the half reset option and select it.
If the issue persists, consult a service technician.
