Replacement USB Display for VT110, VT212 & VP18 Controllers
The Expert VT110 Top Display Board (part #E330‑0531) is a direct OEM replacement USB display module used in AP® Expert Series ventilation controllers, including the VT110, VT212, and VP18 models. This top-mounted display unit provides the essential visual interface for navigating menus, adjusting environmental settings, and viewing real-time barn conditions.
If your controller’s screen is blank, unresponsive, or failing to read USB files, replacing the display board is often the fastest and most cost-effective solution—no need to replace the entire controller.
Designed for plug-and-play compatibility, this board allows quick installation with minimal downtime in swine or poultry barns. It also restores full access to key features like USB data transfer, alarm viewing, temperature readings, and ventilation curve adjustments.
The Expert VT110 top display board is your controller’s user interface—handling real-time display, navigation, and USB functions.
Why & When to Replace It:
You should consider replacing this board if:
-
Display issues: LCD fails, becomes dim, ghosted, lines/characters missing.
-
Unresponsive controls: Buttons or arrows stop working or act erratically.
-
LED indicators go dark: You lose status lights (fan, heater, alarm) despite correct operation.
-
USB port malfunction: Prevents you from loading new firmware or backing up settings.
-
Electrical damage: Socket arcing, burnt traces, water ingress, or corrosion.
-
Preventive maintenance: Older units near end-of-life, or you’re preempting downtime.
Without a functioning top board, you’ll lose your primary human–machine interface—(mostly crippled system visibility and usability) even if the controller is still running.
