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.

THEORY OF OPERATION
The VT76X6E series uses a Viconics proprietary adaptive logic algorithm to control the
space temperature. This algorithm controls the heating 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.
Fig.2 - On-Off mechanical control vs. PI electronic control.

*Scheduling consecutive events to the same time will cause the Terminal Equipment
Controller to choose the last event as the time at which it will set its schedule. In the above
example for Saturday, the Terminal Equipment Controller will control to the occupied set
point from 8:00 AM until 11:59 PM. Since it is desired to be in occupied mode throughout
the night, then it is necessary to schedule the first event on Sunday at 12:00 AM. The
Terminal Equipment Controller will force a one minute unoccupied period for a one minute
period (between 11:59 PM and 12:00 AM on Saturday).

This section of the menu permits the user to set a permanent schedule
hold, which bypasses the internal Terminal Equipment Controller
scheduling.
The permanent schedule hold function is typically used for non-
scheduled events that extend for various periods of time.
Enabling a permanent occupied or permanent unoccupied schedule hold
will cancel any active override.
The use of temporary setpoints during permanent hold is permitted. The
duration of the temporary setpoint is as set per the TOccTime parameter.
