Resideo Braukmann w7220a1000 Economizer Logic Module with Dcv Commissioning 24V

Product Description

The Resideo Braukmann W7220A1000 is an economizer logic module designed for rooftop HVAC units that require precise outdoor air management and demand control ventilation. This control module works with Series 72 actuators that operate on a 2 to 10 VDC signal to manage damper position. HVAC technicians and commercial building service pros use this module to automate fresh air intake based on occupancy and indoor air quality conditions. The W7220A1000 supports both occupied and unoccupied operating modes, allowing the system to reduce ventilation during off-hours and restore full airflow when the building is in use. This reduces energy consumption without sacrificing indoor air quality. When paired with a compatible 2 to 10 VDC CO2 sensor such as the C7232, the module enables demand control ventilation, or DCV. DCV adjusts the outdoor air damper position based on real-time carbon dioxide levels in the occupied space. As CO2 rises, the damper opens further to bring in more fresh air. As CO2 drops, the damper closes to conserve conditioned air. This approach meets ASHRAE 62.1 ventilation requirements while cutting heating and cooling loads. The module also supports exhaust fan mode, coordinating exhaust airflow with fresh air intake to maintain proper building pressure. The W7220A1000 operates on 24V at 50 to 60 Hz, making it compatible with standard commercial HVAC control circuits. It handles operating temperatures from -40F to 150F and humidity levels from 5 to 95 percent relative humidity, non-condensing. This range covers most rooftop unit environments including cold climates and hot, humid regions. Commissioning tools are built in to simplify startup and field verification. This module is a reliable choice for economizer retrofits and new rooftop unit installations where DCV and energy code compliance are required.

• Controls rooftop HVAC economizer dampers using Series 72 two-position and modulating actuators on a 2 to 10 VDC signal
• Supports demand control ventilation when connected to a compatible 2 to 10 VDC CO2 sensor such as the C7232
• Occupied and unoccupied mode switching plus exhaust fan mode for full system coordination

Product Highlights

The Resideo Braukmann W7220A1000 delivers economizer control with built-in DCV capability for rooftop HVAC units, helping technicians meet ventilation codes and reduce energy use through precise damper management and CO2-based airflow adjustment.
