Viconics VT7600 Programmable Thermostats
Product Overview
The VT7600 PI thermostat family is specifically designed for single-stage and multi-stage control of heating/cooling equipment such as rooftops 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 an 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 into 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 ( see ordering notes below ).

Important notice
All VT7600 series controls are for use as operating controls only and are not safety devices. These instruments have undergone rigorous tests and verifications prior to shipment to ensure proper and reliable operation in the field. Whenever a control failure could lead to personal injury and/or loss of property, it becomes the responsibility of the user/installer / electrical system designer to incorporate safety devices ( such as relays, flow switch, thermal protections, etc…) and/or alarm system to protect the entire system against such catastrophic failures. Tampering of the devices or missing application of the device will void the warranty.
