My new control unit was already installed when my associate and I bought our dwelling nearly twenty years ago. It’s a undoubtedly easy plastic dial that requires manual adjustment & serves only a single function. While my husband & I have completed extensive remodeling, my associate and I overlooked the control unit. We’ve replaced windows, added insulation & installed ceiling fans to help increase the efficiency & comfort of the home. We’ve invested into new electrical wiring, bathroom renovation & state-of-the-art appliances to improve convenience. When the HVAC specialist worked on the heating system in the fall, I complained about the high cost of bi-weekly heating bills. He recommended upgrading to a smart control unit. I instantaneously started researching the available models & was amazed by the progress in technology. This week’s generation of control units allows easy & remote access through an app on the smartphone, but from virtually someplace in the world at any time of the day or night, I’d be able to make adjustments to temperature. Plus, the control unit would automatically cater to my family’s schedule, conserving energy when we’re asleep or the dwelling is empty. The control unit would know the ideal time to start up the heating system or cooling system to welcome us dwelling to perfect comfort. Advanced control unit options give features such as energy tracking, service reminders & alerts for power outages. They can even control air quality accessories such as humidifiers or media media air cleaners. My largest concern is deciding which control unit to buy. I like the idea of a learning control unit that creates a program according to our preferences, comings & goings. I am also interested in control units that feature geofencing. I want a model that lights up when I approach & responds to voice commands.
