WTL-GBC-00 Johnson Controls Control Server

Overview

The Johnson Controls WTL-GBC-00 Control Server serves as the application server and core hub for the Wireless Pneumatic Thermostat LoRa (WTL) Series system. Operating alongside a paired WTL Gateway, the control server enables the integration of legacy pneumatic thermostat infrastructure with modern building management systems. It provides a centralized platform for managing data, configuring schedules, and interfacing with building automation architectures.

Features

• Web Application Interface: Offers an intuitive web-based user interface for system configuration and management.
• Centralized Database: Stores and tracks historical data logs, system trends, and diagnostics.
• Advanced Scheduling: Supports customized occupant comfort control with occupied, unoccupied, weekday, weekend, holiday, and special day schedules.
• System Notifications: Provides automated email and text alert notifications for system events and user updates.
• Thermostat Capacity: Allows mapping and management of up to 125 WTL thermostats per individual control server.

Specifications

• Power Requirements: Powered via an external adapter supporting 90 VAC to 264 VAC, 36 W. Device input rating is 12 VDC at 3 A.
• Communications: Equipped with two RJ-45 Ethernet connectors supporting network transmission speeds of 10 Mbps, 100 Mbps, and 1000 Mbps.
• Supported Protocols: Communicates natively through BACnet/IP to facilitate seamless building integration.
• Operating System: Built on the Microsoft Windows 10 platform.
• Environmental Conditions: Operates efficiently between -4°F to 131°F (-20°C to 55°C) within a non-condensing relative humidity range of 10% to 90%.
• Enclosure Material: Durable aluminum extrusion construction with heavy-duty steel, meeting IP40 ingress protection requirements.
• Physical Dimensions: Measures approximately 4.7 inches high by 9.33 inches wide by 2.05 inches deep (120 mm x 237 mm x 52 mm), weighing 3.97 lb (1.8 kg).

Applications

The WTL-GBC-00 Control Server is primarily applied in commercial and institutional building retrofits where existing pneumatic zoning systems are upgraded to digital wireless control. It acts as the operational bridge linking a LoRaWAN wireless thermostat network to an overarching Building Automation System (BAS) via BACnet/IP. Additionally, it can function independently as a standalone scheduling and tracking engine for facility managers when a primary BAS infrastructure is not deployed.
