Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The ECS-961neo Temperature Controller is a versatile device designed for precise temperature management in various refrigeration units. It features both a user menu and an administrator menu, allowing for flexible control and enhanced security. The user menu is primarily for adjusting temperature settings, while the administrator menu, protected by a password, prevents unintended operational mistakes, ensuring the system's stability and reliability.

This controller is equipped with a single NTC sensor dedicated to monitoring room temperature. It utilizes a robust 17A (max) relay, capable of directly controlling a single-phase 1.0HP (220VAC) load, making it suitable for a wide range of refrigeration applications. The device boasts a large display screen that provides clear visibility of the current status, complemented by dedicated indicator lights for the compressor and defrost functions. These visual cues enable users to easily monitor the operational state of their refrigeration units.

Function Description:

The ECS-961neo offers comprehensive temperature control capabilities. Users can define the maximum (HSE) and minimum (LSE) set points for temperature, allowing for a customizable operating range. The controller incorporates sophisticated fault probe management with "Ont" (controller on time) and "OFt" (controller off time) parameters. If both are set to zero, the compressor remains off. If "Ont" is non-zero and "OFt" is zero, the compressor remains continuously on. When both are non-zero, the compressor operates in a duty cycle, providing controlled cooling even in the event of a probe fault.

A "Compressor relay activation delay" (dOF) can be configured to prevent short cycling, extending the lifespan of the compressor. The "Delay in activation output after the instruments is switch on" (Odo) parameter allows for a delayed start of the output after the controller powers on, further protecting the compressor.

Defrost management is a key feature, with a configurable "Defrost cycle" (dit) that determines the frequency of defrost operations. The controller offers three modes for counting the defrost interval: compressor running time, natural time, or compressor closing time, providing flexibility based on system requirements. A "Delay for start of first defrost after request" (dOH) can be set to postpone the initial defrost cycle. The "Defrost time" (dEt) parameter defines the duration of each defrost, with a setting of zero disabling defrost entirely. The "dPO" parameter determines whether the instrument should enter defrost mode upon startup, offering an immediate defrost option if needed.

The display mode during defrost (ddL) can be customized. Users can choose to display the real room temperature, display the temperature at the start of defrost until the room temperature reaches the set point, or display "dEF" during defrost until the room temperature reaches the set point. This allows users to select the most informative display for their specific needs. The controller also supports both cooling (HC=0) and heating (HC=1) modes, making it adaptable to various thermal management applications.

Usage Features:

The ECS-961neo is designed for ease of use, with a straightforward key operation system. To set the temperature, users press and release the "Set" button to enter the user menu, where the "set" light illuminates. The "Set" key then displays the current set point value, which can be adjusted using the up/down arrow keys. Pressing "Set" again or waiting 30 seconds saves the new set point and returns to the display status.

Accessing the administrator menu requires pressing the "Set" key for at least 5 seconds, which prompts for a password (PA1). If a password is set (PA1≠0), users must enter the correct password using the up/down arrow keys. Once authenticated, users can navigate through various parameters like diF, HSE, CA1, and ddL using the arrow keys. The universal password for administrator access is 125.

Parameter values can be easily adjusted within the administrator menu. After selecting a parameter code, pressing "Set" displays its value, which can then be modified using the up/down arrow keys. Pressing "Set" again saves the change and returns to the parameter display status.

The controller also supports a manual defrost function, activated by pressing the defrost key for 3 seconds. This allows for on-demand defrosting when necessary.

Maintenance Features:

The ECS-961neo includes features to simplify maintenance and ensure long-term reliability. A parameter value recovery function can be initiated by pressing both the up arrow and "Set" keys simultaneously for 10 seconds while the controller is in temperature display status. This displays an "rSt" code, indicating that the controller has been reset to its default parameters.

The device supports a copy card function (CPK-4) for convenient programming and backup. Users can upload parameters from a programmed controller to a copy card by first programming the controller manually, then connecting the copy card and pressing the "Set" key until "up" code is displayed. After 5 seconds, the copy card can be removed.

Conversely, parameters can be downloaded from a copy card to the controller by connecting the copy card and pressing the "Set" key until "do" code is displayed. After 5 seconds, the copy card can be removed. This feature is particularly useful for configuring multiple controllers with the same settings or for restoring configurations after a reset or replacement.

The controller provides special display codes to assist with troubleshooting. "E1" indicates a probe failure, "Er" signifies a copy card failure, and "EP" suggests that the copy card data does not match the controller data. "rSt" confirms parameter recovery, "do" indicates a successful download, and "up" indicates a successful upload. "LOC" signifies that the room temperature set point is locked, preventing modification. These codes help users quickly diagnose and address potential issues, minimizing downtime and simplifying maintenance.
