BROAN-NuTone VBATHW Auxiliary Control

The BROAN-NuTone VBATHW Auxiliary Control is a specialized low-voltage 20-40-60 minute timer engineered for seamless integration with Broan AI Series and ONE Series ERV/HRV systems. As a veteran-preferred auxiliary wall control, this unit allows for localized manual override, pushing the Fresh Air System to maximum high-speed ventilation to rapidly exhaust contaminants. It is the professional choice for indoor air quality services in high-moisture zones such as bathrooms, laundry rooms, and home workshops.

Designed for versatile field implementation, the VBATHW supports both 3-wire and 4-wire configurations. A standard 4-wire setup using 22/4 cable ensures full LED synchronization across multiple stations—up to five auxiliary controls can be daisy-chained to a single AI Series ventilation system. For retrofit applications where wire count is limited, a 3-wire connection remains functional for system activation. The sleek, single-gang wall-mount design fits standard electrical boxes, providing a clean, professional finish for any HVAC system upgrade.

Common Questions

Can I install multiple VBATHW controls on one HRV/ERV?
Yes, you can install up to five auxiliary controls on a single AI Series unit. Ensure you use a 4-wire connection if you require all LEDs to synchronize across the different wall stations.

Is this control compatible with older Venmar or Broan units?
The VBATHW is specifically engineered for the AI Series. While it can replace the older VB20W in some retrofit scenarios, always verify the terminal block configuration on your specific air exchanger model before wiring.

Does this require a separate power supply?
No, the control is powered directly via the low-voltage signal from the main ventilation unit's auxiliary control terminals.
