Product Overview
The VT7300 PI thermostat family is specifically designed for fan coil control. The
product features a backlit LCD display with dedicated function menu buttons 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 On/Off, 3 point floating and analog 0 to 10 Vdc control.
All models contain can control three, two or single fan speed. 3 additional inputs are
also provided for monitoring and / or various advanced functions.
All models feature configurable System and Fan button functions to meet all possible
applications. They all contain an SPST auxiliary switch that can be used to control
lighting or auxiliary reheat.
The thermostats are also compatible with the new TACO PIR cover accessories. Thermostats equipped with a PIR 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 can be ordered
with or without a factory installed PIR cover (see notes below ).
