Nuheat Home Touchscreen Programmable Thermostat Operating Manual

Nuheat Home Touchscreen Programmable Thermostat 

Thank you for choosing
nVent NUHEAT Home!
You have chosen the most advanced thermostat to control your nVent NUHEAT Electric Floor Heating System. This manual will cover each of the features of the Home thermostat.

SYSTEM TESTS

The Home thermostat features a series of diagnostic tests to confirm the thermostat is installed and functioning properly. The System Tests option is available the first time the thermostat is connected to power or after a factory reset is initiated.

SETUP WIZARD

The Home thermostat features a Setup Wizard to guide you through the basic setup process. The Setup Wizard is available the first time the thermostat is connected to power or after a factory reset is initiated. Refer to section 4 on page 15.

GFCI
The Home thermostat has a built-in GFCI (Ground Fault Circuit Interrupter). The GFCI protects against risks of electrocution caused by the current leakage. If the current leakage exceeds 5 mA, the GFCI will automatically be triggered, thus cutting power to the floor heating system. To indicate the fault, a message will appear on the screen informing you of the fault. To reset the GFCI, press the button on the right side of the thermostat. If the problem persists, contact nVent NUHEAT at 1.800.778.WARM(9276).
