Integrated Programmable Controls

RenewAire’s Integrated Programmable Controls optimize the usability and performance of our commercial ERVs by improving functionality, enabling intelligent controls, streamlining operations and boosting efficiencies. This is accomplished via sophisticated factory-installed microprocessor controls and sensors that provide stand-alone ERVs with Direct Digital Control (DDC) and/or Building Management System (BMS) control interface.

Key Benefits

Optimize usability:
  • Maximize ERV functionality and intelligent control via remote Ethernet accessibility and BMS connectivity without third-party interface.
  • Streamline operations by easily managing and changing ERV control parameters via an advanced user interface.
  • Increase uptime reliability through constant system monitoring.
  • Achieve cleaner and healthier indoor air via IAQ-based ERV control.
Improve performance:
  • Support effective and efficient ERV performance with real-time data trending and logging capabilities.
  • Enhance ERV control via access to real-time airflow rates, airstream temperature and airstream humidity.
  • Facilitate fast and easy ERV upkeep and maintenance with real-time fan, filter and bypass status.
Increase capabilities:
  • Expand ERV connectivity via access to a wide range of open standard protocols, including BACnet and Modbus.
  • Broaden ERV interoperability by connecting to third-party equipment and receiving third-party signals for unit control.
  • Expand ERV-application scope by meeting new code requirements and the needs of institutional customers requiring DDC controls in mechanical equipment.
Simplify operations:
  • Achieve easier ERV setup, commissioning and balancing via simple-to-install controls.
  • Improve operational efficiencies by easily communicating ERV status, airflows, temperatures and humidity.
  • Allow for more flexible installations by enabling ERVs to be interconnected with a BMS, operated independently or run in concert with other ERVs.

Models and Features

Standard Controls
via dry contact and relays

Our ERV units are provided with a dry contact that can be used to control the unit with a variety of low-voltage (24VAC) control devices such as remote switches or relays. In addition, third-party analog output can be used to operate the ERV.

NEW - Enhanced Controls
Carel [c.pCOMini] with or without BACnet

Enhanced controls offer automated control, including temperature and humidity control with data trending via microprocessor controls and sensors that enable BMS connectivity.

NEW - Premium Controls
Carel [c.pCOMini] with expansion module with or without BACnet

Premium controls include all functionality of enhanced-controls capabilities, as well as airflow and IAQ monitoring, demand control, electric or gas heating options, as well as RD-Series cooling and heating control.
