HTPG EcoNet Enabled Unit Coolers: Evaporator Controller

Key Features and Benefits

The EcoNet Enabled Unit Coolers are intelligent, electronically operated evaporators that contribute to significant energy savings in refrigeration systems. They achieve this through precise superheat and space temperature control, optimized fan cycling, and intelligent defrost scheduling based on compressor runtime. This technology helps eliminate unnecessary defrost cycles, reduces compressor runtime, and mitigates icing issues, ultimately improving product quality and system efficiency.

These controllers are versatile, capable of configuring for single or dual evaporator coils and can be integrated into systems with single or multiple evaporator installations as a group.

System Installation and Setup

The manual details the process of system installation, including connecting power to the evaporator unit and ensuring all sensors and relays are securely connected. It supports both 230 VAC and 115 VAC power supplies, with automatic voltage detection. Important safety considerations, such as proper lockout procedures and avoiding contact with live components, are emphasized.

Guidance is provided on refrigerant line brazing, purging lines, and charging the system, with specific instructions on monitoring critical parameters like suction pressure, temperature, and superheat.

Operation and Maintenance

The document outlines the controller's navigation system, allowing users to access settings, status information, and service menus. Key settings covered include Set Point, System Enabled, Group Configuration, Network Instance, and Time & Date. The Status Overview section details how to monitor various sensor readings, digital inputs, and system outputs.

Maintenance information includes details on supported refrigerants and EXV stepper types, along with references to specific sections for leak detection and other operational limits.
