Sequence Of Operation; Temperature Sensors - Carrier VAV Zone II Installation And Startup Manual

Sequence of operation

Sequence of operation
The VAV Zone II supports 3 types of pressure-independent terminal configurations:

Single duct

Series fan-powered

Parallel fan-powered
The controller can operate as part of a linked system (VAV or VVT) or as a stand-alone controller.

Temperature sensors

The VAV Zone II supports the following temperature sensors:
Sensors
Space temperature sensors:

Wireless Standard or Plus

ZS Standard, Plus, Pro

T55 3

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).
If the zone has ducted reheat, install an SAT sensor downstream of the
reheat source. The SAT is used in controlling the reheat.
If heat is not supplied, install the SAT sensor in the duct on the terminal's
leaving air side.
The SAT determines the air source mode should Linkage communication
fail or if the controller is stand-alone. See Air Source Mode Determination
(page 57) for details.
