How to Change Honeywell Thermostat Temperature

In this post, we cover how to change temperature setting on Honeywell thermostat, model RTH9580WF.  Now most Honeywell digital t-stats nowadays allow you to change their current temperatures right from the  Home screen.  They display the  Home  screen by default. So unless the t-stat is in lock mode, you can adjust the current temp. Simply press the on screen or button temperature controls.  If your t-stat screen goes blank due to inactivity, just tap the screen area. Then the  Home   screen will display, similar to our RTH9580WF WiFi t-stat shown next.

How to Change Honeywell Thermostat Temperature: Locally

Press the  UP   arrow on the right side of the  Home   screen to increase the temperature.  Press the  DOWN  arrow to reduce it.  Each press changes the current temperature by one degree.

How to Handle a Locked Thermostat Screen

Now you might not be able to change the current temperature setting if your thermostat in screen lock.  You might see the following screen in that case.

If your thermostat is in lock mode, then do either of the following to change temperature.

• • Unlock it.
  • Access it via the Honeywell Total Connect Comfort web site or app.

See our   How to Lock and Unlock Honeywell Thermostat RTH9580WF   post for how to unlock your smart Honeywell thermostat.

Changing Thermostat Temperature Temporarily or Permanently

Now your t-stat likely follows a program schedule. So when you touch the temp arrows, it prompts to switch to either permanent or temporary hold. Se this in the next picture.  While ours was following a schedule, we locally changed its temperature to 69 degrees. Then we got the following Hold Switch screen.

Here we could either press the   Switch to Permanent Hold   button, which places the t-stat into permanent hold.  Or we could just press the green   Done   button. This puts the t-stat into temporary hold, until 10:00 PM in this case, as shown in the   HOLD UNTIL   field.

Temporary Hold

Now you can opt for temporary hold. If you do, then you can set the time you’d like the programmable thermostat to resume following its schedule. For that, press the UP and DOWN arrows in the  HOLD UNTIL field area. Press them to zero in on the desired ending time for the temporary hold.  By default, the RTH9580WF switches back to schedule following at the next scheduled temp change time. In our program, that is 10:00 PM.  E.g. The temp of 69 degrees we just changed to, stays in effect thus, until ten PM.  Then, the system applies the temperature in the programmed schedule at that time.  Then, the t-stat loses our temporary hold setting.

Permanent Hold

You could also opt to keep your changed temperature setting in effect in perpetuity, by switching to  permanent hold.  To do that, press the   Switch to Permanent Hold   button for this.

From either the permanent hold or temporary hold versions of this screen, you could cancel the hold altogether. To do that, press the   Cancel Hold   button.  Doing so would return your thermostat to   Following Schedule   mode. Thus, this undoes the temperature setting you just changed.  The scheduled temperature for the current time would then take effect again.  You must choose some kind of hold to keep your temperature change in effect.

To opt for permanent hold, press the green  Done   button.   This takes you back to the  Home  screen, showing the new temperature setting.

How to Change Honeywell Thermostat  Temperature: Remotely

If you have set up an account on the  Honeywell Total Connect Comfort  web site, then register your thermostat there. After that, you can change its current temperature setting remotely, on that web site.

Visit the  TCC web site,  and log in with your previously set up TCC account.  You’ll see the TCC home screen then.  Now you may have more than one t-stat on your account.  If so, then choose the one whose temperature setting you want to change.

Ours looks like this.  We’re going to change the temp on our unit called THERMOSTAT, in our apartment group.

Press the  UP  arrow in the center of the thermostat control screen. This increases the temperature. Or press the  DOWN arrow to lower it.  Furthermore, each press changes the remote t-stat’s temperature setting by one degree.

Then once the setting you wish appears, press the red   Submit   button. This  sends the change to your t-stat and brings it into effect.  Keep in mind thought that this change may not happen right away.  E.g. They apply the new setting within a minute or two.  Doesn’t matter whether you lock the thermostat. Indeed you can still change the temperature from the web site or app, without unlocking.

Note that the whole talk about permanent and temporary hold above, also applies when you change the temp remotely.  But we’re not going to include the screen shots from the TCC website here, unless readers ask for them.

You’ve now successfully changed your Honeywell thermostat temperature setting.
