(Forced by time 0 N/OFF)
(Forced 0N/off by time)
When the temperature sensor is short-circuited, it is forced to operate on/off mode by time.
When the tempature sensor is short-circuited, it is operated by force by force by time.

If you turn on the power switch, the current temperature is displayed in the display window.
When you ON the power switch, the current tempature is displayed on the display window.
Set the desired temperature with the up/down switch (green lamp illumination).
Set the desired template with the up/down switch (green lamp light)
The output (red lamp) turns on when the load is electrically charged.
When the load flows electricity, the output (red lamp) is turned on.

When the set temperature is reached, the red lamp turns off and automatically maintains the set temperature.
When it attached the set tempature, the red lamp turns off and keeps the set tempature automatic.
In case of malfunction due to program error of the thermostat, unplug the power cord and reconnect it after 10 seconds.
In case of solution due to a program error of the program, unplug the power code and connect it after 10 seconds.
All applications will be initialized.
All programs are initialized.

Please unplug the power cord when you are away or out of the power cord must be unplugged.
Be sure to unplug the power cord when not in use or when you are away.
When using the thermostat, make sure to keep the proper amount.
Be sure to keep the alternative account when using the thermostat.
