Honeywell TC500A-N Thermostat Details

The Honeywell TC500A-N Thermostat is an advanced, connected device designed for commercial buildings, offering extensive control and monitoring capabilities for Rooftop Units, Heat Pumps, and Fan Coil Units, along with their accessories. It integrates seamlessly into building automation systems via Wi-Fi, Bluetooth, BACnet I/P over Wi-Fi, BACnet MS/TP, and Sylk protocols. This wide array of communication options ensures flexibility and ease of integration within diverse commercial environments.

This thermostat incorporates sophisticated intelligent control algorithms to achieve an optimal balance between energy efficiency and occupant comfort. It comes pre-packaged with numerous presets, making the initial setup both quick and straightforward for most commercial building requirements. The device's firmware can be conveniently upgraded over Wi-Fi and MS/TP networks, ensuring it remains up-to-date with the latest features and security enhancements.

The TC500A-N features a user-friendly and highly customizable interface, allowing for personalized settings and intuitive navigation. It supports multiple, configurable levels of user privilege access, enabling administrators to control who can modify setpoints, schedules, special events, language, units, and screen lockouts. This security feature prevents unauthorized changes, maintaining system integrity and operational efficiency.

Beyond basic temperature control, the thermostat includes advanced commercial control algorithms such as changeover, scheduled purge, power-up delay, freeze protection, and demand limit controls. It also leverages reliable optimized recovery methods proven over decades of use in Honeywell commercial thermostat models, further enhancing energy savings and system performance. The device's real-time clock ensures accurate timekeeping, even retaining settings for up to 72 hours during a power loss.

For remote management, users can connect to the thermostat via Wi-Fi using the Honeywell Connect Me app. This mobile application provides authorized users with remote access to monitor sites, manage schedules, adjust settings, and override controls from virtually anywhere. It also facilitates device configuration and user management, offering comprehensive control from a mobile device.

The thermostat also includes an LED indicator that shows its operational status, particularly useful when the display enters sleep mode due to inactivity. Configuration can be performed directly through the Human-Machine Interface (HMI), the Honeywell Connect Mobile app, or via BACnet, offering multiple avenues for setup and adjustment. BACnet settings can be further fine-tuned using the Honeywell TC500A BACnet Wizard tool.

Security is a paramount concern, and the manual emphasizes the need for an Internet firewall to isolate the thermostat from cyber threats. It also recommends keeping local servers and thermostat firmware up-to-date with the latest security patches. Furthermore, the use of strong, unique passwords for different user roles is advised, discouraging the use of default credentials to enhance system protection.

The device supports a wide range of external sensors, including occupancy, dirty filter, proof of airflow, shutdown, mixed air temperature, outdoor air temperature, return air temperature, discharge air temperature, space temperature, CO2, proof of waterflow, window open, and drain pan/leak detectors. This extensive sensor compatibility allows for comprehensive environmental monitoring and precise control, adapting to various building needs and optimizing HVAC operations.

The integral economizer feature, when enabled, allows for intelligent use of outdoor air for free cooling and ventilation, further reducing energy consumption. This system can be configured with Demand Control Ventilation (DCV) using CO2 sensors to regulate fresh air based on occupancy levels. The purge function rapidly flushes building air for improved indoor air quality, which can be scheduled for specific times.

Frequently Asked Questions (FAQs)

Can't find the answer you need? Here are some frequently asked questions about the Honeywell TC500A-N Thermostat, and we answer them below.

What equipment types can the Honeywell TC500A-N control?

The TC500A-N can control Rooftop Unit, Heat Pump equipment, and Fan Coil Units, supporting up to 3 heating stages and 4 cooling stages in conventional systems, or up to 3 compressor stages and 2 auxiliary heat stages in heat pump systems. For FCU, it supports 2-pipe heat or cool only Single coil, or 4-pipe Dual coil configurations.

How can I remotely control or monitor my TC500A-N thermostat?

You can remotely monitor and configure the TC500A-N using the Honeywell Connect Me app (for occupants) or the Honeywell Connect Mobile app (for installers). Both apps connect via Wi-Fi and allow access to schedules, settings, and override controls.

What communication protocols does the TC500A-N support?

The thermostat communicates over Wi-Fi (802.11 b/g/n), Bluetooth (BLE 4.2, Classic Bluetooth), BACnet I/P over Wi-Fi, BACnet MS/TP over RS485, and Honeywell Sylk™.

What are the main display features of the TC500A-N?

It features a 4-inch, 480x480 pixel LCD screen with a touch-sensitive interface. It shows indoor temperature, humidity, current mode, desired temperature, Wi-Fi signal strength, time, and indicators for energy saving or purge functions.

Can the thermostat be configured to save energy automatically?

Yes, it includes advanced commercial control algorithms like an internal economizer for free cooling and Demand Control Ventilation (DCV) using CO2 sensors. It also supports Auto Demand Response (ADR) events from utilities to reduce electricity consumption.

What are the temperature setpoint limits?

Heat setpoints are automatically limited between 40°F to 90°F (4.5 to 32°C), and cool setpoints are limited between 50°F to 99°F (10 to 37°C). Occupied cool setpoint should be at least a deadband value bigger than occupied heat setpoint.

How does the presence detection feature work?

The TC500A-N has a built-in proximity sensor that detects a user's presence up to 1.5 meters away, automatically "waking" the screen for interaction.

What types of schedules can I set up?

You can set up Weekly schedules for day-to-day operations, Holiday schedules for recurring events (up to 10), and Special Event schedules for one-time events, all of which use Occupied, Unoccupied, or Standby setpoint configurations.

How do user roles and permissions work on the thermostat?

The thermostat supports four user roles: Visitor (read-only, optional setpoint adjustment), Basic User (limited read/write access), Admin (full read/write for advanced controls), and Installer (full access to all application elements). Each role can be passcode-protected and have customized permissions.

What is Delta T Diagnostics and what does it do?

Delta T Diagnostics is a tool that measures temperature differences across heating or cooling coils using Discharge Air and Mixed Air sensors. It helps identify performance issues by comparing measured Delta T to configured target ranges and triggers alarms if values are outside the set limits.

How can I reset the thermostat to its default settings?

You can reset the entire thermostat to factory defaults, which deletes all configurations and user data. Alternatively, you can choose to only reset the Weekly Schedule and temperature setpoints to factory defaults, retaining other configurations.

What happens if Wi-Fi is disabled on the thermostat?

Disabling Wi-Fi will restart the thermostat, disable Bluetooth and ADR, suspend communication with the Gateway and Mobile app, and disable BACnet IP communication. Only Admin and Installer users can enable/disable Wi-Fi.

What onboard sensors does the TC500A-N have?

The device has a built-in temperature sensor, humidity sensor, and proximity sensor. It also supports offsets for these onboard sensors to allow for calibration.

Does the TC500A-N support external economizers?

Yes, it supports external economizer integration. You can enable this feature if economizer sensors and actuators are connected to an additional economizer module, requiring specific I/O configurations for proper operation.

What is the purpose of the Purge function?

The Purge function is designed to rapidly flush the building's air volume using a high percentage of outdoor air, typically just before or after occupancy. This is done to improve indoor air quality and can be scheduled with configurable fan speed and damper positions.
