Product Overview


The VT7600 PI thermostat family is specifically designed for single stage and
multi-stage control of heating/cooling equipment such as rooftop and self-
contained units. The product features an intuitive, menu-driven, back-lit LCD
display, which walks users through the programming steps, making the
process extremely simple. Accurate temperature control is achieved due to
the product’s PI time proportional control algorithm, which virtually eliminates
temperature offset associated with traditional, differential-based thermostats.

All models contain two digital inputs, which can be set by the user to monitor
filter status, activate a remote temporary occupancy switch, and/or used as a
general purpose service indicator. In addition, depending on the model, up to
three remote sensor inputs are available. All models contain a SPST auxiliary switch, which can be used to
control lighting or disable the economizer function and a discharge air sensor input. For more advanced
applications, an economizer control logic has been integrated onto the thermostat for use with proportional
damper economizer actuators.

The thermostats are also compatible with the new Viconics PIR cover accessories. Thermostats equipped
with a PIR cover provide advanced active occupancy logic, which will automatically switch occupancy levels
from Occupied to 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.
