Many newer energy efficient homes, especially those insulated with spray foam, are built extremely "tight" and require fresh air ventilation. Fortunately, the Comfort Window thermostat comes equipped with a ventilation control timer.
Comfort Window's built in ventilation timer helps to regulate the amount of fresh air brought into a house. The ventilation controller can be configured to drive either the system fan or use our dedicated output (ECD). Set the number of minutes per hour of fresh air required to ensure indoor air quality, without needlessly wasting energy.
"Ventilation controllers on the market today typically run between $80 and $120."
