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 Viconics 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.
