Honeywell Wi-Fi Thermostat Case Study

Bob's New ThermostatDo you remember our previous post about smart thermostats?  A good friend of mine, Bob, went out and bought the Honeywell Wi-Fi unit at Home Depot for $249 and tax. Our Service Technician, Kevin Burns, installed it in Bob’s home in an attic office.  It took 30 minutes to install the hardware and another 30 minutes to install the software and answer all Bob’s questions.  Bob reports that when Kevin left, Bob was programming the unit from his computer and iPhone. He was also able to set up the daily schedule from the unit’s touch panel without ever having to consult the manual, watch a video, or call Kevin.  Bob really likes the vacations feature (where you put in the dates you will be away) that overrides the regular schedule.  Another great feature is that the unit will turn on the heat on a cold day, and as the day warms up it will turn on the air conditioning.  No manually operated switch is required.  Kevin pointed out that to display the outside temperature you don’t have to run any wires to a sensor.  The unit uses Wi-Fi to get the temperature and humidity from the Internet. signature

Smart Thermostats

Do you remember Bill Richards talking about the new technology in thermostats. Well there are now two smart thermostats sold at many retailers including Lowes and Home Depot.   Currently the retail price is the same for both at about $250. You can install them yourself, or call us and we will send a professional installer that has experience with these devices.

thermostatHoneywell offers the touch screen WiFi  Smart Thermostat.   There are apps that permit control of your home comfort from any place with Internet access or in your room on the couch using a computer, tablet, or smartphone.  You can also control your system with its touch screen on the wall.  The Honywell unit allows you to match your décor with different colored screens.  Extreme temperature alerts and filter change reminders are sent to your connected network devices and are displayed on your Honeywell Wi-Fi smart thermostat Extreme temperature alerts and filter change reminders are sent to your connected network devices and are displayed on your Honeywell Wi-Fi smart thermostat Extreme temperature alerts and filter change reminders are displayed on your mobile device or displayed on the thermostat.  Details here.

thermostatThe popular Nest Learning Thermostat is now in its 2nd Generation. Its 20% thinner, can save you even more energy and works with 95% of low voltage systems.  It takes about a week for the thermostat to learn your routines. Nest also uses WiFi to provide for remote control by computer, tablet or smartphone. If you are away it turns the Nest down when you're not home while Auto-Schedule learns what temperatures you like and programs itself; you can also adjust Nest's schedule at any time .It displays your energy history which shows you how much energy you've used and what affects your energy use most. Details here.

How do you choose which one is best for you?   Its whether you prefer a  rectangular unit or a  round unit.  That's the main obvious difference  between the two.signature

How new technology home thermostats are introduced?

Bill Richards, Service Manager, discusses this process.

We introduce new products to our residential customers by making these things an option. The option of installing it, the option of upgrading; as we well know this is a world of gadgets and different things that people like. I think using the cellphone to help is a really nice feature. For instance if you were to plan to come home unexpectedly early and you need a new setback,  before you leave the office, connect to the Internet and change the temperature before you get home. The Honeywell Presitige is a really nice thermostat that has many features. So that's kind of how we operate at Interstate.  It’s not a must to operate heating and cooling but its such a nice option and with many new features it's something home owners really enjoy on their heating and cooling system.
