"0H". Use the UP or DOWN arrow buttons to set the number of hours the
heater will remain on (1H-9H, where 1H = 1 hour and 9H = 9 hours). After 5
seconds, the setting will be locked in.
Note: If this feature is not selected, the heater will continue to operate to
maintain the desired temperature.

between Fahrenheit and Celsius. Repeat this operation to switch from Celsius

8. Once the controller is programmed, the heater will cycle on and off to
maintain the desired room temperature. To prolong the heater's lifespan,
after reaching the desired temperature, the heating element will turn off, but
the fan will continue to operate for approximately 3 minutes to cool down the
heater. This fan delay off feature also activates when the heater is manually
turned off while heating. The fan will continue running to cool down the
heater.
9. To turn off the heater, press the red POWER button. If the heater is operating,
it will turn off, but the fan will continue running for about 3 minutes to allow
the heater to cool.
NOTE: When operating the unit for the first time, you may notice slight smoke.
This is normal and caused by residual cleaning agents used during
manufacturing to clean the heating element. This smoke will dissipate after a
few minutes of operation and does not indicate a problem with the unit.
