A GFCI/GFEP (Ground Fault Circuit Interrupter / Ground Fault Equipment Protection) works differently than a circuit breaker by specifically detecting a small imbalance in electrical current between the hot and neutral wires, which indicates a potential ground fault (like a person touching a live wire), and instantly shutting off the power to prevent shock, while a circuit breaker only trips when there's a significant overload in current flow on the circuit, like a short circuit or too many appliances plugged in.

It is highly recommended to use a smartphone for the initial thermostat setup. Download the nJoy UWG5 app and ensure Bluetooth is enabled on your phone. Open the app, tap "Get Connected," and follow the on-screen instructions to complete the setup.

Note: The thermostat will not appear in your phone’s Bluetooth device list. Use the nJoy UWG5 app to complete the connection.

A factory reset will erase all settings, including schedules, temperature preferences, and Wi-Fi or Bluetooth connections. After resetting, you will need to set up the thermostat again, including re-pairing it with your mobile app.

This option allows you to restore the thermostat to factory settings.
PLEASE NOTE: This action cannot be undone, and all of your personal settings will be lost.

Additionally, if your thermostat was paired via Bluetooth with the UWG5 (nJoy) app, follow these steps to remove it from the Bluetooth list:

1. Open the UWG5 (nJoy) app.
2. If logged into your online account, tap the Bluetooth icon in the lower-left corner.
3. Locate the thermostat on the list (e.g., a greyed-out entry like “Bathroom 2”).
4. Long press on the thermostat name, then select Delete to remove it from the Bluetooth list.

Note: This action does not remove the thermostat from the iOS Bluetooth pairing list due to Apple’s system restrictions. If using an iPhone, you may need to manually remove the thermostat from your device’s Bluetooth settings.

Relays can fail due to excessive current or voltage. When a relay is exposed to too much current, the contacts can burn out. High voltage can also damage the coil. Other reasons include mechanical wear and tear, dust or dirt buildup, and moisture. These factors can cause the relay to malfunction or stop working entirely. Regular maintenance and using the relay within its specified limits can help prevent failures.

GFCI can fail for various reasons, such as wear and tear, moisture, corrosion, power surges, faulty wiring, or improper installation. Some of these causes can be prevented by regular inspection and maintenance, while others may require professional assistance. It is important to note that GFCI devices (ex. thermostat, breakers, outlets) should be tested regularly as these do wear out over time.

No, a circuit breaker will NOT protect against a power surge; a circuit breakers primary function is to protect against excessive current flow (overload), while a surge protector is specifically designed to handle voltage spikes, which are what power surges are considered to be.
