Overview

Convenient Package

Small enclosure allows you to easily mount controller directly to VAV boxes.

Easily Addressable

Two decimal rotary switches (0-9) allow simple addressing – no hex, no binary.

Removable Screw Terminals

Allows for quick replacement.

Status Indicators

Bright on-board LEDs assist in troubleshooting.

Flexible Sensor Capability

Supports 10K Type III thermistors or a selection of digital display wall stats.

Tech Specs

Power Supply Input 24VAC ± 20% 50/60Hz Class 2 transformer
Power Requirements 3VA Quiescent, 75VA full load
Analog Input Types Three total: Configurable for either resistance (10K Type III thermistor), or voltage 0-10VDC input. Analog In 3 is configurable for use with MN-S3-700 display stat option.
Analog Output Types One selectable voltage source output as either 0-10VDC @20mA max analog output, or as fixed 24VDC @100mA max loop source.
Binary Output Types Four 24VAC triac controlled outputs, increasable to 6 outputs (420 mA max per output).
Damper Outputs Two 24VAC triac controlled damper outputs, one internal damper output for floating damper, and the second configurable externally accessible damper output for either floating or non-floating actuators.
Note: the second external damper can also be reconfigured as two independent 24VAC triac outputs, increasing the total fixed binary output types to six.
Electrical Connections Pluggable terminal blocks, capable of accommodating 14-22 AWG wire.
Communication Ports RS485 and RS232 communication ports.
Microprocessor Intel 386EX, 25MHz, 1 MB Flash ROM, 512k RAM, Real Time Clock with 10yr + Lithium battery backup.
Dimensions 5-1/2" W x 4-1/4" L x 1-1/2" H
Ambient Limits Operating Temperature: 32 to 158 °F
Shipping and Storage: -40 to 160 °F
Humidity: 5 to 95% RH, non-condensing

  • VAV-P.pdf
  • VAV with pressure pickup - the VAV-P provides a conveniently small package when you need airflow measurement, but are controlling air flow through external means.

  • VAV-AP.pdf
  • VAV with actuator and pressure pickup - the VAV-AP provides both air flow control and measurement for our most complete VAV solution.

  • VAV-A.pdf
  • VAV with actuator - the VAV-A is the perfect solution when you want to control the space temperature by adjusting air flow, or when the air flow cannot be measured directly.
