Product Overview
Distech CDIB-VAXX-IMP-10 BACnet Controller
The Distech Controls CDIB-VAXX-IMP-10 ECB-VAV BACnet Controller is a programmable variable air volume (VAV) controller used to control VAV boxes in commercial HVAC systems. It communicates over BACnet MS/TP and combines configurable inputs and outputs with an onboard airflow sensor and built-in damper actuator for applications including cooling-only, cooling with reheat, dual-duct, parallel-fan, and series-fan VAV boxes
Part Details:
- ECB-VAV programmable VAV controller with BACnet MS/TP communication and B-ASC BACnet profile
- 10 configurable I/O points: 4 universal hardware inputs, 4 digital Triac outputs, and 2 universal outputs

FAQs:
Q: What is the Distech Controls CDIB-VAXX-IMP-10 used for?
A: The CDIB-VAXX-IMP-10 is a programmable ECB-VAV controller used to control variable air volume boxes in HVAC systems. Supported applications include cooling-only, cooling with reheat, dual-duct, parallel-fan, and series-fan VAV boxes.
Q: What communication protocol does the CDIB-VAXX-IMP-10 use?
A: The controller communicates using the BACnet MS/TP protocol. The ECB-VAV series is identified as a BACnet Application Specific Controller (B-ASC).
Q: Does the CDIB-VAXX-IMP-10 have a built-in airflow sensor?
A: Yes. The controller includes an onboard differential-pressure airflow sensor with a range of ±2.0 in. W.C. (±500 Pa) and polarity-free high/low pressure connections.
Q: Does the CDIB-VAXX-IMP-10 include a damper actuator?
A: Yes. It has an integrated brushless DC actuator rated for 45 in-lb (5 Nm) of torque with 95° adjustable rotation.
Q: What types of sensors can be connected to the CDIB-VAXX-IMP-10?
A: The universal inputs support resistance, voltage, and digital inputs. The manufacturer's specifications include support for thermistors and RTDs from 0 to 350 kΩ, 0-10 VDC and 0-5 VDC signals, and 0-20 mA signals when used with the specified external resistor.
