TB7200 Series Thermostat      TB7200 Series Thermostat with Occupancy Sensor

APPLICATION

The TB7200 Series PI thermostat family is specifically designed for zoning applications. The TB7200 Series are communicating thermostats with models available in BACnet® MS/TP and ZigBee® wireless mesh protocols and can be easily integrated into a WEBs-AX building automation system based on the Niagara^AX® platform.

Typical applications include local hydronic reheat valve control and pressure dependent VAV with or without local reheat. Accurate temperature control is achieved due to the product’s PI proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differentialbased thermostats. Models are available for 3 point floating and analog 0 to 10 Vdc control. In addition remote room sensing is available.

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 and ZigBee wireless protocols
• 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 at any time
• Pre-configured sequences of operation means one model meets more application needs
• Password protection to minimize parameter tampering
• Four levels of keypad lockout to limit access to change user parameters such as setpoints, system mode, etc.
• Available in 24 Vac on/off, floating or 0-10 Vdc analog control to meet advanced applications requirements
• Three configurable inputs for monitoring and advanced functions
• SPST auxiliary output that can be used for lighting or reheat
• All wiring connections are made to removable terminal blocks simplifying installation

Theory of Operation

The TB7200 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 TB7200 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.
