FEATURES
● Models available with internal humidity sensing...increased occupant comfort
through dehumidification
● Advanced occupancy functions through the network or smart local occupancy
sensing
● 3 configurable inputs...adds functionality
● Configurable sequences of operation...single model meets more applications
● Configurable fan functions button...meets more applications with a single model
● Unique local configuration utility...minimizes parameter tampering
● Multi-level lockable keypad...tamper proof, no need for thermostat guards
● Auto Fan speed mode...increased occupant comfort in cooling mode by reducing
humidity and less fan noise in all modes of operation
● Auxiliary output...can be used for lighting or reheating

DESCRIPTION
The VT73xxC5x PI thermostat family is designed for fancoil control. The product
features a backlit LCD display with dedicated function menu buttons for simple
operation. Accurate temperature control is achieved with the PI proportional
control algorithm, which virtually eliminates temperature offsets associated with
traditional, differential-based thermostats. All models can control three, two, or
single fan speeds. Three additional inputs are also provided for added functionality.
All models feature configurable System and Fan button functions to meet a range of
applications and an auxiliary contact that controls lighting or auxiliary reheating. All
devices are also available with Echelon or BACnet MS-TP network adapters.
APPLICATIONS
● Three-speed fans
● Heating/Cooling valves
● Electric duct heaters
● Changeover sensors
