Honeywell WiFi Thermostat Registration Instructions

In order to control your Honeywell thermostat remotely through the internet, you must run through the Honeywell WiFi thermostat registration routine at the  Honeywell Total Connect Comfort (TCC)   web site.  So here, we walk you through that on the RTH9580WF smart thermostat.





Honeywell WiFi Thermostat Registration Instructions: First Steps

1. Install your Honeywell WiFi Thermostat

Skip this step if you’ve already installed your thermostat and it is powered on, and showing its home screen.  If you haven’t, see our Honeywell Smart Thermostat Wiring Instructions RTH9580WF post for tips on mounting and wiring this new t-stat.

2. Connect your T-stat to your WiFi Network with Internet Access

Skip this step if you’ve already connected your thermostat to an internet-ready Wi-Fi network at its installed location.  If you haven’t, then see our Change WiFi Network on Honeywell Smart Thermostat RTH9580WF piece for instruction on how to link your thermostat to your home or office wireless network.

3. Create an Account on the TCC Web Site Honeywell WiFi Thermostat Registration

You’ll need a working account over there in order to register your thermostat and control it remotely.  Again, skip this step if you’ve already set up a TCC account.  If you have not, then visit the TCC web site here, and on the login page, click the  Create an Account  button, and then follow the instructions.

4. Gather Thermostat Info 

In order to add your thermostat to your TCC account, you’ll need its MAC address and CRC code.  This information is printed in the documentation that accompanies new Honeywell thermostats.  However, you may also obtain it from the thermostat itself, as follows.  If you have this information already, then skip ahead to Step 5 below.

Note that in our scenario, we connect the thermostat to our 937T681J4059H_2G wireless network, though it is as of yet,  unregistered.  You should have connected yours to the network you pointed it at in Prerequisite Step 2 above.

We’ve “pink-painted over” our thermostat’s MAC address and CRC value in these pictures.

If this is the first time you’ve signed into the TCC web site, and you’ve never set up any locations before, then you’ll see the following screen. You must set up at least one location to register your thermostat in.  We detail how to do that in the steps following.
