Thermostats

rodgersMany of our customers have a multi-stage programmable thermostat from White Rodgers (on right). This is a very sophisticated thermostat and a great fit with the geothermal heat pump systems.  Thermostats effectively don’t wear out but we would like to make you aware of some new products which have more attractive interfaces and incorporation of additional features.

Radio Thermostat – CT-30

The Radio Thermostat CT-30 was one of the first broad offerings for connection to your home’s wireless network.  It was picked up by 3M and is sold under their Filtrete products name.   Aztech has a number of these installed in the field and at employees homes with very good success.  The CT-30 is the least expensive of Wi-Fi systems we recommend and this particular model has limited staging capabilities and will not be appropriate for all systems.  The touchscreen with a white backlit display works well. Call for price.

    • Any web connection
    • Smartphone apps from Android or iPhone
  • Works well with more than one zone
    • One touch occupied or un-occupied settings for all linked zones
  • 7 day programmable with 4 independent periods per day
  • Single touch “Set Away” or “End Away” covering multiple zones
  • Can be linked to some home automation systems

The Nest – Generation 2

The second generation Nest Thermostat was designed and manufactured by some former Apple iPad developers. It has a great look and unique interface, as you might expect from this team. The newest version can support our multi-stage heat pumps, has a proximity sensor to aid in auto programming and can turn itself down if it senses you are not home. The ability to program itself by making a schedule based on your first week’s temperature adjustments is neat but less useful for geothermal heat pump systems since regular changes of more than a few degrees can hurt efficiency. The user interface from the web or smartphone apps are easy to use and provide a lot of interesting information about your system. Call for price.
