Questions and Answers

Heater Cycles ON;OFF Without Heating

Smart heater monitors room temp, produces heat only when needed.

Heater Cycles But Doesnt Produce Heat

Ensure desired temperature is set higher than room temperature.

Turning Off the Heater

Switch to STANDBY mode or POWER OFF the heater.
