Testing a thermostat

Let’s discuss testing. Good thermostats begin with the set up. Installations can differ broadly from thermostat to thermostat and HVAC system to HVAC system, however there are some primary steps required for putting in these gadgets. As at all times, seek the advice of knowledgeable installer when you’ve got any questions concerning the setup course of. Listed here are the final steps:

  • Flip off energy to your thermostat on the circuit breaker
  • Take away the previous thermostat
  • Set up the thermostat’s baseplate with the included screws
  • Connect the wires to the wire terminals 
  • Snap on the faceplate
  • Activate energy on the circuit breaker

Was the thermostat setup particularly troublesome to put in? In that case, why? Sure fashions require a C-wire, for instance, which might complicate the set up if you do not have one. Unsure what a C-wire is? Begin right here

From there, I transfer on to the app. Each sensible thermostat has one. I obtain the app and create an account if I do not have already got one. Then I configure the thermostat following the steps within the app. This often means connecting to the native Wi-Fi community, giving your thermostat a reputation like “Hallway” or “Bed room” after which you can begin utilizing your thermostat.

How properly does the app work? Is it straightforward to navigate to the thermostat settings you want? Is it easy to create a schedule or allow geofencing? This components into the thermostat’s usability rating, together with how easy the thermostat itself is to regulate manually. 

I additionally take a look at sensible dwelling integration, particularly voice-enabled programs you possibly can entry by means of voice assistants like Alexa, Google Assistant or Siri. Most related thermostats are compatible with no less than one voice assistant and a few, just like the Ecobee3 Lite and Ecobee SmartThermostat, work with all three. Do the voice instructions move naturally, like they’d in an precise dialog? Did the thermostat really modify the temperature — heating and cooling — in response to your instructions? 

All of these items decide a wise thermostat’s general rating and the way possible I’m to suggest it.
