Vykon VT76X7 User Manual

Product overview
The VT76x7 PI thermostat family is specifically designed for single stage
and multi-stage control of heating/cooling equipment such as rooftop and
self-contained units with humidifier and/or dehumidifier. The product
features an embedded complete humidity solution with an intuitive, menu-
driven, backlit LCD display that walks users through the programming
steps, making the process extremely simple. Accurate temperature &
relative humidity 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 one digital input, 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. The two models contain a SPST auxiliary switch, which can be used to control lighting or disable the
economizer function and a discharge air sensor input.
The thermostats are also compatible with the new Vykon 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 ordering
notes below ).
