| Power Supply Input | 24VAC ± 20% 50/60Hz Class 2 transformer |
|---|---|
| Power Requirements | 2VA 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. |
| Actuator Outputs | Torque Rating: 53 lb.-in. (6 N-m) Stroke: Full adjustable from 0° to 90° Timing: Approximately 3 minutes at 60 Hz (3.6 minutes at 50 Hz) for 90° rotation @ 24 VAC Position Indicator: Provides a visual indication of position. Manual Override: Push-button to allow manual positioning on the damper. Damper Linkage: 1/2" (12.75 mm) or 3/8" (9.5 mm) diamater round shaft extending 7/8" (22.23 mm) minimum from terminal box. |
| 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 | 5-3/4" W x 7-1/4" L x 2-1/2" H |
| Ambient Limits | Operating Temperature: 32 to 158 °F Shipping and Storage: -40 to 160 °F Humidity: 5 to 95% RH, non-condensing |
| Enclosure | Surface mount. Conforms to NEMA-1 requirements. Meets UL94-5V flammability for plenum application use. |
| Agency Compliance | E195258 UL 916 (PAZX) Energy Management Equipment Canadian Standard C22.2 No. 205-M1983 E231285 UL 61010C-1 (QUYZ) Electrical Process Control Equipment Canadian Standard C22.2 No. 1010 CE IEC 61010-1 (1990) with Amendments 1 (1992) and 2 (1995) |

- 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-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-X.pdf
- VAV with no actuator or pressure pickup - the VAV-X, our smallest VAV solution, is used when direct air flow measurement and control are not required.
