• If 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 wrong 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 verication prior to
shipping to ensure proper and reliable operation in the eld. 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, ow 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.

Features overview

• C02 control logic based on fresh air volume or fresh air damper position.

• Fresh air damper output for building CO2 level control.

• Gas, oil or electric system compatibility.

• Remote outdoor sensing capability for added exibility.

- System mode heating and cooling lockout.

• Remote discharge air sensor input for monitoring and control purpose.

- System efciency feedback.

- Discharge high limit heating lockout.

- Discharge low limit cooling lockout.

• Remote return air sensor input that replaces internal on board sensor.

- System efciency feedback.

• Password protected conguration menu and lockable keypads for security.

• Automatic smart fan operation saves energy during unoccupied periods.

• Non volatile EEPROM memory prevents loss of parameters during power short­age.

• Congurable SPST output relay on scheduling models for lighting, exhaust fan or
fresh air control.

• 6 hour typical reserve time for clock in case of power loss.

Easy conguration and self-binding operation

• Easy conguration without using any special software or additional tools.

• Can be used as stand-alone or with BACnet™ MS-TP supervision controller for
monitoring purposed.

The fresh air damper can be controlled through more than one sequence to achieve
different control strategies such as free cooling (economizer mode), minimum fresh air

control and CO2 level control. Here are the control sequences available:

Note: For the sequences mentioned below, the following conditions must be
met in order for the sequences to be performed as stated:

- Max Pos parameter value must be greater than Min Pos Parameter value.

- Mac CO2 parameter value must be greater than Min CO2 Parameter value.

- Max FA parameter value must be greater than Min FA Parameter value.

Economizer Control Mode Only

If the fresh air damper is to be used only for free cooling purposes (economizer mode,
without fresh air measurement station or CO2 control), only the Min Pos parameter
and the free cooling sequence will be active.

- The FA Range parameter should be set to 0 CFM. (Default Value = 0 CFM)

- Set the Chngstpt parameter to desired value which free cooling is enabled.

(Default Value = 55°F)

If the outside air temperature is greater than the changeover setpoint, then normal
mechanical cooling will be used. If the outside air temperature is less than or equal
to the changeover setpoint, then free cooling will be enabled and mechanical cooling
stages will be locked out.

Economizer Mode and Fresh Air Measurement Station

If the fresh air damper is to be used for both free cooling and minimum fresh air vol­ume control (economizer mode and fresh air measurement station, but without CO2
level control), only the Min FA parameter and the free cooling sequence will be active.

- The FA Range parameter should be set to a value higher than 0 CFM (0 CFM
disables the fresh air control).

- Min FA (minimum fresh air) parameter should be set to the desired level.

The FA Range parameter value should be set to the maximum capacity of the fresh
air measurement station. Therefore the relationship between air volumes and input
signals can be established. For example, if the fresh air station capacity is 10000
CFM, set FA Range to 10000.

This will set the relationship of 0 VDC = 0 CFM and 10VDC = 10000 CFM.

Economizer Mode and CO2 Level Control

If the fresh air damper is to be used for both free cooling and CO2level control (econo­mizer mode and CO2 level control, but without fresh air measurement station), only
the Min Pos, Max Pos, Min CO2and Max CO2 parameters as well as the free cooling
sequence will be active.

- The FA Range parameter should be set to 0 CFM.

- Set AI1 parameter to CO2 (0 VDC = 0ppm ; 10VDC = 2000ppm)

- Min Pos, Max Pos, Min CO2 and Max CO2 parameters should be set accord-

ing to the required setting.

Current CO2 Level

The highest value between free cooling demand output and interpolation output for
the fresh air setpoint will be the output to the fresh air damper.

Economizer Mode, CO2 Level Control and Fresh Air Measurement Station

If the fresh air damper is to be used for both free cooling and CO2 level control with
a fresh air measurement station, only the Min FA, Max FA, Min CO2 and Max CO2
parameters as well as the free cooling sequence will be active.

- The FA Range parameter should be set to something other than 0 CFM.

- Use an air ow transmitter to read fresh air level with AI2 input (0-5 VDC

input)

- Min FA, Max FA, Min CO2 and Max CO2 parameters should be set according
to the required setting.

Current CO2 Level

The highest value between free cooling demand output and interpolation output for
the fresh air setpoint based on the CO2 level will be the output to the fresh air damper.
