Element Thermostat V2
SKU Code
Conserving energy doesn’t mean you have to sweat in the summer and freeze in the winter. As part of your Vivint Smart Home system, the Element thermostat uses your security system and sensors to know when you’re home, asleep, away, or on vacation. Using that information, it automatically adjusts, keeping you comfortable when you’re home and conserving energy when you’re not. Using the Vivint Smart Home app, you can access your thermostat and control the temperature in your home from anywhere, at any time. Thanks to integration with Amazon Alexa and Google Assistant, you can even adjust the temperature with the sound of your voice. And with an elegant design than blends into your home’s interior, its illuminated controls fade out as you walk away.

Installation instructions

Factory reset Element Thermostat V2

Reset will restore the thermostat settings to the factory defaults. It will also disconnect the thermostat from the
Z-Wave network.
1. Press the DOWN arrow to highlight Reset, then press the SIDE button.
2. Confirm that you want to reset the thermostat, select yes, then press the SIDE button. The thermostat resets.

Please use this procedure only when the network primary controller is missing or otherwise inoperable.

The thermostat’s node type is pre-determined when it connects to the Z-Wave network; if the C-Wire is not connected and is only battery-powered when connecting to the network, the thermostat will remain a frequent listening routing slave (FLiRS) node until it is removed from the network.

When your thermostat is running on battery power, the Z-Wave radio will turn off to help conserve battery life. The thermostat Z-Wave radio module supports Z-Wave beaming, which allows other devices in the network to wake up the Z-Wave module and accept commands and then go back to sleep.

When your thermostat is running on C-Wire power, the Z-Wave radio will stay on and actively help route messages within the Z-Wave network. The thermostat’s node type is pre-determined when it connects to the Z-Wave network; if the C-Wire is present and powered when connecting to the network, the thermostat will remain an always-listening node until it is removed from the network.
