If your Lennox thermostat is showing an error code of 413, this indicates a high-pressure lockout that affects your outdoor unit. If you see this code, please contact an HVAC company right away to inspect your HVAC system for issues.
The thermostat could be showing a malfunction for several different reasons.
First, ensure it's is working physically at the thermostat on the wall. If it's not, you can find further assistance here.
If it's working from the physical thermostat on the wall:
Have you relocated any Z-Wave devices in your home? Some of these act as a repeater for the Z-Wave signal for other devices. If any Z-Wave devices have been moved from their original location, try returning them back to where they were previously to see if the thermostat malfunction clears.
If no changes were made and the thermostat appears to be working otherwise, give us a call at 1.800.PROTECT (1.800.776.8328) for further assistance.
There are a few different things you can check if your thermostat is not properly controlling the HVAC system.
1. Is your thermostat in malfunction on your app or website? Find more info on thermostat malfunctions here.
2. Ensure your HVAC system is getting power. Please make sure no breakers or switches are turned off that power your HVAC system.
3. You may need to wait 5 minutes when you switch from heat and cool modes. The compressor will be delayed by 5 minutes.
If you have checked the above and still need assistance, just give us a call at 1.800.PROTECT (1.800.776.8328). Depending on the issue, our team may recommend you contact an HVAC company. We recommend Armstrong Comfort Solutions for all of your heating and cooling needs.
There are a few different things you can check if your thermostat is changing the set point temperature on its own. Please use the below check list for more information.
Check your thermostat schedule on MyGuardianHome.com. Your thermostat could be changing the temperature because it is running this schedule. You have the option of using a feature called Smart Away with thermostat schedules. This allows the temperature to be set to your Away temperature when you have your system armed in Away mode or when your device leaves your geo-fence.
You may be enrolled in a feature called Give Back, Get Back. This feature will allow your energy provider to offset your thermostat setpoint during peak hours to lesson the load of the power grid. To remove this feature:
1. Log into MyGuardianHome.com.
2. In your thermostat card, click the > icon.
3. Click Give Back, Get Back.
4. Click Settings and Notifications.
5. Click the toggle switches to disable Give Back, Get Back Sign Up and Notify for Give Back, Get Back Activity.
6. Click the X to close the window.
You may be using a Scene that involves your thermostat. Check your Scenes under Automation on MyGuardianHome.com or in the Guardian app under Scenes.
Your thermostat may have the ability to program a schedule on the thermostat itself. These thermostats are usually installed by your home builder. Please see the manual of your thermostat or contact your builder for more information on your thermostat.

If your thermostat fails to light up after changing the batteries, please call us at 1.800.PROTECT (1.800.776.8328) to schedule a service visit.
If your thermostat does not have batteries, then it gets its power from your HVAC system. Please make sure the HVAC system is has power, and ensure that you do not have any electrical breakers flipped.
To change the batteries on your Z-Wave smart thermostat, please watch this quick video:
If this isn't your thermostat, the steps to changing the batteries may be different:
In most 2GiG thermostats (including CT100 Z-Wave thermostat), the bottom or top portion of the thermostat will slide off the faceplate to reveal the battery compartment.
If you have a Honeywell thermostat, on most models, press around the edges of the faceplate to loosen the thermostat from the mounting plate. Then pull the thermostat away from the wall. You will see the batteries located on the back of the thermostat.
If you are unsure on what model of thermostat you have, or none of the above instructions match what is installed in your home, please give us a call at 1.800.PROTECT (1.800.776.8328).
