Overview
The Automatic Off Function in Fujitsu General’s VRF system is a smart feature designed to enhance energy efficiency by automatically turning off the air conditioning system after detecting inactivity for a set duration. This functionality helps reduce energy consumption, especially in spaces with intermittent occupancy, such as offices, conference rooms, and hotel rooms.
Key Features of the Automatic Off Function
Occupancy-Based Control:
Utilizes external inputs, such as occupancy sensors or keycard systems, to monitor room usage.
Customizable Timeout Duration:
Allows the user to set the inactivity duration before the system powers down automatically.
Energy Savings:
Prevents unnecessary energy usage by shutting off the system when the space is unoccupied.
System-Wide Integration:
Works seamlessly with other VRF features, such as the keycard interlock and human sensor functions.
Use Cases
Hotel Rooms: Automatically turns off air conditioning when guests leave the room without removing the keycard.
Conference Rooms: Shuts down cooling or heating after meetings to prevent wasted energy.
Office Spaces: Ensures unused areas are not unnecessarily cooled or heated after working hours.
Setting Up the Automatic Off Function
Install Necessary Hardware:
Ensure an external input device, such as an occupancy sensor or keycard system, is installed and connected to the VRF unit using the appropriate terminals (e.g., UTY-XWZXZD connection kit).
Access Function Settings:
Use the remote controller or central control panel to navigate to the function setup menu.
Set Function Parameters:
Enter the Function No. and Setting No. corresponding to the Automatic Off Function:
Function No.: 46 (External Input Control)
Setting No.: Configure timeout duration (e.g., 15 minutes, 30 minutes).
Save and Test the Configuration:
Confirm the settings and simulate inactivity (e.g., no movement detected or keycard removed) to verify the system shuts off as expected.
