Introduction
Inputs
4 inputs for connecting the following types of sensors:
•
An alternate space temperature sensor (#33ZCT55SPT)
•
Supply air temperature sensor (#33ZCSENSAT)
•
Duct air temperature sensor (#33ZCSENDAT)
•
CO2 sensor (#33ZCSENCO2)
•
Relative humidity sensor (#33ZCSENSRH-02 [indoor space] or
33ZCSENDRH-02 [duct])
•
Remote occupancy sensor
Input resolution
10 bit A/D
Digital outputs
#OPN-VAVB1: 1 digital output
#OPN-VAVB3: 3 digital outputs
Relay contact rated at 1 A max. @ 24 Vac/Vdc. Configured normally open.
Analog output
1 analog output, 0–10 Vdc (5 mA max). The controlled device must have a
minimum of 2000 Ohms resistance measured from its input to ground and
must share the same ground as the controller.
Output resolution
8 bit A/D, using filtered PWM
Integral actuator
Brushless DC motor, torque 35 inch-pounds (4 Nm), runtime 205 seconds for
90 degree travel during control, or 25 seconds in high-speed test and balance
mode
Battery
10-year Lithium CR2032 battery retains the following data for a maximum of
10,000 hours during power outages: control programs, editable properties,
schedules, and trends.
Protection
Incoming power and network connections are protected by non-replaceable
internal solid-state polyswitches that reset themselves when the condition that
causes a fault returns to normal.
The power, network, input, and output connections are also protected against
transient excess voltage/surge events lasting no more than 10 msec.
BT485 connector
You attach a BT485 (not included) to a controller at the beginning and end of
a network segment to add bias and to terminate a network segment.
Status indicators
LED's indicate status of communications, running, errors, power, and digital
outputs
Environmental operating
range
0 to 130°F (-18 to 54°C), 0 to 90% relative humidity, non-condensing
Storage temperature range
-24 to 140°F (-30 to 60°C), 0 to 90% relative humidity, non-condensing
Physical
UL94-5VA plenum rated enclosure for installation in plenum (or other space
for environmental air) in accordance with NEC Section 300.22 (c) and (d)
6
VAV Zone Controllers
