Better Control

Bring in the right amount of fresh air at the right time

Many homes rely on exhaust fans to reduce odors and humidity in kitchens or bathrooms. Introducing fresh air into the home can dilute viruses, odors, and other contaminants throughout an entire house – something an exhaust fan in one room can’t do.

The 8120X Ventilation Controller that comes as part of the 8145* lets you set to control the temperature and relative humidity limits that help bring the right amount of fresh air into the home at the right time.
