VAV/Zone Controller Overview
The OE326-23I-OR VAV/Zone Controller is designed for pres-
sure independent VAV Box and Zone Damper applications. It
is supplied with an integral Airfl ow Sensor and is mounted in a
plastic enclosure.
The OE326-23D-OR VAV/Zone Controller is designed for pres-
sure dependent VAV Box and Zone Damper applications and is
mounted in a plastic enclosure.
The OE326-23I-OR and OE326-23D-OR VAV/Zone Controllers
utilize terminal block connections for wiring. The 24 VAC power
is supplied from a transformer (by others) wired to the VAV/Zone
Controller using standard stranded wire and 2 position terminal
blocks. The communications wiring is connected between the
other VAV/Zone Controllers, CommLink 5, MiniLink PD5,
HVAC unit controller or other controllers on the local loop by
using 2 conductor 18 gauge twisted pair with shield wire which
is connected to the VAV/Zone Controllers via a standard 3 posi-
tion terminal block.
Both VAV/Zone Controllers are designed for use with an OE282-
01 Zone Damper Actuator. The VAV/Zone Controller connects
to the actuator via the modular cable that is included with the
actuator.
The VAV/Zone Controller can use a Standard Room Temperature
Sensor wired to the provided 3 position terminal block or an
E-BUS Digital Room Sensor connected via the integral E-BUS
cable connector or to the provided 4 position terminal block. The
VAV/Zone Controller also has a 2 position terminal block for
wiring a Discharge Temperature Sensor, if desired.
A relay output on the VAV/Zone Controller provides for one stage
of electric heat or an On/Off Hot Water Valve if the controlled
terminal unit is not a fan terminal unit.
An optional Expansion Module is available for applications us-
ing fan terminals and/or more than 1 stage of electric heat, SCR
electric heat, or modulating HW heat. The Expansion Module
connects to the VAV/Zone Controller by means of a prefabricated
E-BUS cable.
