Product overview VT7200 Series 24 Vac Low Voltage Zoning Thermostats For Commercial HVAC Applications 1 The VT7200 PI thermostat family is specifically designed for zoning applications. Typical applications include local hydronic reheat valve control and pressure dependent VAV with or without local reheat. The product features a backlit LCD display with dedicated function menu keys for simple operation. Accurate temperature control is achieved due to the product s PI proportional control algorithm, which virtually eliminates temperature offset associated with traditional, differential-based thermostats. Models are available for 3 point floating and analog 0 to 10 Vdc control. In addition remote room sensing is available. They all contain an SPST auxiliary switch that can be used to control lighting or auxiliary reheat. All devices are also available with Echelon or BACnet MS-TP network adapter. The additional following documentation is available on www.viconics.com Information on the LON models (VT72xxX1000E), is available on document ITG-VT7200-LON-E01 Information on the BACnet models (VT72xxX1000B), is available on document ITG-VT7200-BAC-E01 For more application information including detailed wiring, specific configuration and sequences of operation, please refer to online document APP-VT7200-E01.
