PERATION
The VZ765 series uses a Viconics proprietary adaptive logic algorithm to control the
space temperature. This algorithm controls the heating and or air conditioning system to
minimize overshoot while still providing comfort. It provides exceptional accuracy due to
its unique PI time proportioning control algorithm, which virtually eliminates temperature
offset associated with traditional, differential-based on/off thermostats.

 When replacing an existing Terminal Equipment Controller, label the
wires before removal of the Terminal Equipment Controller.
 Electronic controls are static sensitive devices. Discharge yourself
properly before manipulating and installing the Terminal Equipment
Controller.
 A short circuit or improper wiring may permanently damage the Terminal
Equipment Controller or the equipment.
 All VT7000 series Terminal Equipment Controllers are designed for use
as operating controls only and are not safety devices. These instruments
have undergone rigorous tests and verification prior to shipping 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 or installer or electrical system designer to
incorporate safety devices (such as relays, flow switch, thermal
protections, etc…) and or an alarm system to protect the entire system
against such catastrophic failures. Tampering with the devices or
unintended application of the devices will result in a void of warranty.
