SCW-120-15A Frequently Asked Questions

In Step 2 of the process, where you attempt to connect directly to the Decora Smart Wi-Fi device that is listed in the Wi-Fi networks (it will be listed in the format of Leviton Device-xxxx), instead of connecting you receive a message stating it is "unable to connect" or simple never connects (e.g. no check mark next to the device).
If the device connects and you see this screen, skip to Decora Smart Wi-Fi device will not connect to the Wi-Fi Network or Leviton Cloud.
If the mobile device does not connect to the Decora Smart Wi-Fi device at this step, please follow these troubleshooting step:

1. Make sure you have the latest version of the My Leviton App. To ensure that you are running the latest version of the app, check for a My Leviton app update on the Apple App store or Google Play store.
   
2. If available, try using a different mobile phone or tablet running the My Leviton app. Follow Steps 1 and 2 and see if you are able to connect to the device. If you are able to connect, see if you can complete the process.
3. Contact our technical support team at dssupport@leviton.com. Please include the type and model of mobile devices you are using and the model number of the Decora Smart device.

GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.

When the design requirement's amp draw exceeds the selected controller's capacity.

It depends on how the system is intended to operate. If the expectation is manual operation (ex. WiFi or Timer Control), then no sensors are required. If the expectation is automatic operation, then the system will require at least one snow sensor.

Ground fault equipment protection (GFEP) is intended to provide protection for equipment against damaging line-to-ground currents by disconnecting all ungrounded conductors of the faulted circuit.

No, a sensor is not required with the snow melt system. However, certain automatic controllers require a temperature/moisture sensor to sense atmospheric conditions and may also require an in-slab, high temperature limit sensor to be installed (notably, asphalt installations).
