Honeywell TB7300 Series Communicating Fan Coil Thermostats User Manual

Honeywell TB7300 Series Communicating Fan Coil Thermostats

APPLICATION

The TB7300 PI thermostat family is specifically designed for fan coil control. The TB7300 Series are communicating thermostats with models available in BACnet® MS/TP protocol and can be easily integrated into a WEBs-AX building automation system based on the NiagaraAX® platform. Thermostats equipped with an occupancy sensor cover provide advanced active occupancy logic, which will automatically switch occupancy levels from Occupied to Stand-By and Unoccupied as required by local activity being present or not. This advanced occupancy functionality provides advantageous energy savings during occupied hours without sacrificing occupant comfort. All thermostats are PIR ready and can be ordered with or without Honeywell
occupancy sensor. The occupancy sensor cover is available to order separately if a PIR is needed at a later time.

FEATURES

• Available in BACnet MS/TP protocol.
• Backlit LCD display with dedicated function menu keys for simple operation.
• Fully integrated advanced occupancy functionality with a PIR cover provides energy savings opportunity on select models; all other models are PIR ready and can have an optional occupancy sensor cover added.
• Configurable sequences of operation.
• Configurable fan button allows thermostat to meet more applications with a single model.
• Password protection to minimize parameter tampering.
• Six levels of keypad lockout to limit access to change user parameters such as setpoints, system mode, etc.
• Auto Fan speed mode increases occupant comfort in cooling mode by reducing humidity and reduces fan noise.
• Available for 24 Vac on/off, floating or analog control meets advanced applications requirements.
• Three inputs for monitoring and other advanced functions.
• SPST auxiliary output that can be used for lighting or auxiliary reheat.
• All wiring connections are made to removable terminal blocks simplifying installation.

TB7300 Series Models

Thermostats ordered without an occupancy sensor cover can be retrofitted with an occupancy sensor cover later if needed.

Theory of Operation

The TB7300 uses a proprietary adaptive logic algorithm to control the space temperature. This algorithm controls the heating / air conditioning system to minimize overshoot while still providing comfort. It provides exceptional accuracy due to its unique PI time proportioning control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based on/off thermostats.

IMPORTANT

All TB7300 series controls are for use as operating controls only and are not safety devices. These instruments have undergone rigorous tests and verifications prior to shipment to ensure proper and reliable operation in the field. Whenever a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the user/installer/ electrical system designer to incorporate safety devices (such as relays, flow switch, thermal protections, etc.) and/or alarm system to protect the entire system against such catastrophic failures. Tampering of the devices or miss application of the device will void warranty.
