The GREE E-Smart Zone Controller is a centralized control unit designed for multi VRF air conditioning systems, offering comprehensive management of indoor and outdoor units. This owner's manual provides detailed instructions for installation, display, operation, and various functions, ensuring efficient and effective control of your air conditioning system.

Function Description:

The E-Smart Zone Controller serves as a central interface for managing multiple indoor and outdoor air conditioning units. It allows users to control individual units, groups of units, and the entire system with ease. Key functions include:

All ON/OFF Control: Users can turn all indoor units in the current area ON or OFF with a single press of a button. When turned ON, units will operate according to their last memory settings.
Single Unit Control: This feature enables detailed control over individual indoor units. Users can adjust operation mode (Cool, Heat, Dry, Fan, Auto, Floor heating, 3D heating, Heat supply), set temperature, and control fan speed and swing functions (Up&Down, Left&Right). Advanced control parameters such as Sleep, Quiet, Auto Quiet, E-Heater, Absence, Rapid, and Energy Saving functions are also available for individual units.
Group Control: The controller supports the creation and management of groups of indoor units. Users can add new groups, edit existing groups (including setting group names and adding/removing indoor units), and delete groups. Control parameters for groups are similar to those for single units, allowing for synchronized operation of multiple units. A single indoor unit can be assigned to up to 5 groups.
Timer Setting: The controller offers a robust timer function for scheduling ON/OFF times for units. Users can set specific ON/OFF times, select repeat days (Mon, Tue, Wed, Thu, Fri, Sat, Sun), and configure timer mode, fan speed, and set temperature.
Local Setting: This section allows for customization of controller settings, including sound, language, temperature unit (°C/°F), time format (12hr/24hr clock), date and time, user password activation/inactivation, backlight settings, and customer service information.
Engineering Setting: Designed for professional engineering staff, this section includes indoor unit registration and name setting. Users can register up to 32 indoor units and customize their names and icons for easy identification on the main page.
Operation Notice: Provides access to information regarding local unit status, customer service details, operation instructions, and other important notices.
Malfunction View: If an indoor unit experiences a malfunction, an "Error" icon will be displayed, allowing users to view detailed information about the issue.

Important Technical Specifications:
