Improve air quality by triggering the HVAC ventilation on a daily schedule to refresh the air. Take advantage of the air outdoor temperature by bringing it indoors, not only is the temperature nice, its also fresh! Automate the washroom fans to stay on after the light has been turned off to refresh the air after use. Bathroom and Shower fans can be automated with humidity sensors to remove the steam after a shower with the fan. Once the humidity levels drop, the fan is switched off automatically. Control the Kitchen Extractor Fan, the Bathroom Fans, Ventilation, Heat Exchanger, on demand from your smart phone or tablet or smart home touch screen display controller.
