Can I Monitor and Control the Temperature On a Honeywell L5210?

Yes, you can monitor and control the temperature on a Honeywell L5210. To do this, you will need an L5100-ZWAVE module and a Z-Wave thermostat. You can then access the Automation Menu of the L5210 to control the Z-Wave thermostat. You can also do this from the Total Connect 2.0 platform.

The Honeywell L5210 is a wireless security system that has an Automation Menu for controlling various household appliances. This includes smart thermostats. The system supports nearly any thermostat that uses Z-Wave communication. But the L5210 does not offer Z-Wave connectivity right out of the box. You must add an L5100-ZWAVE card to the system. The L5100-ZWAVE is a system accessory that allows the L5210 to send and receive Z-Wave signals. Without this is add-on the L5210 cannot be used as a Z-Wave controller, and it will be unable to support smart Z-Wave thermostats.

The L5100-ZWAVE module is easy to install inside the L5210 System. You should first open up the panel by pressing on the two tabs at the top. You may need a screwdriver to do this. This disconnect the system's backup battery, and unplug the transformer. You can confirm that the system has fully powered down by checking to make sure the screen is blank. Then secure the L5100-ZWAVE to the main board. Use the Honeywell L5100-ZWAVE Installation Guide to help you. Then reattach the backup battery, and close the panel. Make sure the two (2) upper tabs lock into place. You can then plug the transformer back in. Make sure the system powers back on.

With the L5100-ZWAVE module installed, you can start add a Z-Wave thermostat. You should remember to clear the device from the network before you attempt to add it. This can be done by putting the L5210 into its Z-Wave exclusion mode and then activating the enrollmennt function on the thermostats. Many Z-Wave thermostats are paired with networks as part of factory testing purposes. Clearing the device from the network first will ensure that you can add it successfully. Then pair the thermostat by putting the panel into its Z-Wave inclusion mode, and activate the Z-Wave enrollment function on the thermostat. The device should successfully pair with the L5210.

Once the smart thermostat has been successfully paired with the system, you can access the thermostat menu within Automation on the L5210 to increase or decrease the temperature. Any command for the thermostat will be sent from the L5210 system to the thermostat. The thermostat will then tell the HVAC system to increase or decrease the temperature as needed. The L5210 will also display the current thermostat temperature from the Automation Menu. If you have an alarm monitoring plan that includes access to Total Connect 2.0, you will be able to control your thermostat remotely using the TC2 website and mobile app. You can also use TC2 to create smart scenes so that the Z-Wave thermostat adjusts the temperature automatically based on a set schedule or with certain system events.
