Questions and answers
Hi, the appointment/timer section of the manual makes zero sense. Please clearly explain how to set the heater to come on at a specific time and how to turn off. Be very specific about which button to press first, what comes next and which button to finish etc. A video would be helpful.
Press the reservation (or timer) button to enter the time setting mode. The reservation lamp (or timer lamp) will flash. Adjust the time using the add and subtract keys. The setting will automatically confirm after 5 seconds of no operation or can be confirmed immediately by pressing the reservation (or timer) button again. The reservation lamp (or timing lamp) will stay on continuously after confirmation. You can set both scheduled power-on and power-off times, with the first confirmed setting taking priority. The maximum timer setting is 24 hours, and setting it to 0 hours disables the timer.
