Sequence Of Operation; Temperature Sensors - Carrier TruVu VVTZC-E2 Installation And Startup Manual

Wiring inputs and outputs

Sequence of operation

The TV-VVTZC-E2 supports 3 types of pressure-dependent terminal configurations:
•
Single duct
•
Series fan-powered
•
Parallel fan-powered
The controller can operate as part of a linked VVT system or as a stand-alone controller.

Temperature sensors

The TV-VVTZC-E2 supports the following temperature sensors:
Sensors
Space temperature sensors:
•
Wireless Standard or Plus
•
ZS Standard, Plus, Pro
•
T55 3
Duct temperature sensors:
•
Duct Air Temperature (DAT)
•
Supply Air Temperature (SAT)
1 To configure the control program for the desired user interaction with the sensor, see the Wireless Sensors
Application Guide. For detailed instructions, see the Wireless Sensors Installation Guide.
2
For basic user instructions, see the ZS Sensor User Guide. For detailed installation instructions, see the ZS
Sensors Installation Guide.
3 See the Carrier Sensors Installation Guide for details on T55 sensors.

humidity, and/or CO
Push the sensor's override button from 2 to 10 seconds to initiate a
timed override.
If a network space temperature value is used, that value must be
written to the BACnet space temperature point (system_spt) at 1 to 5
minute intervals or on a COV of 0.1 °F (.06 °C) .
To reference another zone as your space temperature input, read the
BACnet point zone_temp by using the network point System Space
Temperature.
10K Type II.
If the zone does not have ducted reheat, install a DAT sensor on the
inlet of the damper.
If the zone has ducted reheat, install an SAT sensor downstream of the
reheat source. The SAT is used in controlling the reheat.
The DAT/SAT determines the air source mode if Linkage
communication fails or if the controller is stand-alone. See Air Source
Mode Determination (page 65) for details.
