TC500A BACnet Integration Guide7High voltage safety test
Experienced electricians, at first contact, always assume that hazardous voltages may exist in any wiring system. A safety check using a known, reliable voltage measurement or detection device should be made immediately before starting work and when work resumes.Lightning and high-voltage danger
Most electrical injuries involving low-voltage wiring result from sudden, unexpected high voltages on normally low voltage wiring. Low-voltage wiring can carry hazardous high voltages under unsafe conditions. Never install or connect wiring or equipment during electrical storms. Improperly protected wiring can carry a fatal lightning surge for many miles. All outdoor wiring must be equipped with properly grounded and listed signal circuit protectors, which must be installed in compliance with local, applicable codes. Never install wiring or equipment while standing in water.Wiring and equipment separations
All wiring and controllers must be installed to minimize the possibility of accidental contact with other potentially hazardous and disruptive power and lighting wiring. Never place 24VAC or communications wiring near other bare power wires, lightning rods, antennas, transformers, or steam or hot water pipes. Never place wire in any conduit, box, channel, duct or other enclosure containing power or lighting circuits of any type. Always provide adequate separation of communications wiring and other electrical wiring according to code. Keep wiring and controllers at least six feet from large inductive loads (power distribution panels, lighting ballasts, motors, etc.). Failure to follow these guidelines can introduce electrical interference and cause the system to operate erratically.Warning

CHAPTER1About TC500A9INTRODUCTIONAbout TC500ATC500A-N/TC500A-W Thermostat is an advanced, configurable, connected device for commercial buildings. It controls and monitors Rooftop Unit, Heat Pump equip-
ment, and their configurations. This device communicates over Wi-Fi, Bluetooth, Sylk, and easily integrates with the building automation system.The built-in intelligent control algorithms of the device help to achieve the perfect balance between Energy Efficiency and Comfort. The device is packaged with numerous presets suitable for most commercial building requirements that enable the easy and quick initial setup. The firmware of the device can be upgraded via Wi-Fi network. The device has four universal terminals and a pair of Sylk terminals to connect with sensors or other accessories. It also has a built-in temperature sen-
sor, humidity sensor, and proximity sensor.Users can connect to the thermostat via Wi-Fi with the Honeywell Connect Me app. The Honeywell Connect Me app gives authorized users access to the Honeywell TC500 Thermostats in their commercial buildings. They can remotely monitor sites, schedules, settings, and override controls. Users can add and configure devices, manage users and more – all from a mobile device.Scope of the documentThe BACnet Integration document contains information related to BACnet Objects and its properties of the thermostat that helps engineers to integrate and config-
ure the settings via a BACnet tool.Reference documents•TC500A Commercial Thermostat User guide (31-00400M-02)•TC500A Commercial Thermostat Datasheet (31-00398M-02)•TC500A Commercial Thermostat Mounting instructions (31-00399M-02)•TC500A Commercial Thermostat Quick start guide (31-00401M-02)
