VT7200 Series
24 Vac Low Voltage Zoning Thermostats
For Commercial HVAC Applications
(Issue Date August 10, 2007 – 028-0122 R6)
Product overview
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.
