NOTE: When you first use your unit, or when you plug the unit into an electrical wall socket to start to use, operation manner has been set to Auto Fan mode.
NOTE: When the circulation water at the temperature of 100˚F ( 38˚C ) or more flows into the unit, the fan will start rotating.
If the temperature of the circulation water is less than 100˚F ( 38˚C ), the fan will not start rotating. If the temperature of the circulation body of water is between 100˚F ( 38˚C ) and 110˚F ( 43˚C ), the unit will operate at humble fan speed. When the temperature of the circulation water is more than 110˚F ( 43˚C ), the sports fan amphetamine is adjusted mechanically according to the place temperature and the room temperature.

  1. Turning Unit ON
    Press Power switch. The current room temperature and the set temperature will be shown on the digital display.
    POWER lamp will light and will hear a beep sound.

    Adjusting Room Temperature
    A. Press the “–/hour” or “+/min.” button. the “ ˚ ” marks will start to flash.
    NOTE: “–/hour” or “+/min.” button will change the temperature every 2˚F (1˚C).
    B. Press the “–/hour” or “+/min.” button as required. Room temperature can be set from 50˚F – 90˚F (12˚C – 30˚C). (Initial setting: 68˚F (20˚C))
    NOTE: Desired temperature setting will be displayed on the digital display when you set the room temperature.
    C. When room temperature exceeds the selected setting by approx. 4˚F (2˚C), the Fan will automatically stop. As room temperature drops, the Fan will automatically re-start to maintain the desired temperature.

    NOTE: Initial setting of the temperature in Fahrenheit. If you like to change to Celsius, contact your dealer.

  2. Turning Unit OFF
    Press Power switch. The POWER lamp will go out and there will hear a beep sound. The current time will be shown on the digital display. If the clock is not set, two sets of dashes will be shown.
    NOTE: When the unit is turned off, always stop the circulation of the hot water to the Heat convector.
    If a circulation pump control is connected to the external output terminal, the Circulation pump will stop automatically when the Heat convector is turned off.

AUTO FAN OPERATION
The Auto Fan mode shifts the sports fan speed mechanically to adjust the room temperature according to the typeset temperature.

  1. Press the Power switch. The current room temperature and the set temperature will be shown on the digital display. The power lamp will light. If the unit is set to Auto Fan mode, “AUTO” is shown on the digital display. If “MANUAL” is shown on the digital display, press the AUTO FAN/MANUAL FAN button to switch the fan mode.
  2. Press the “-/hour” or “+/min.” button as required. Room temperature can be set from 50˚F – 90˚F (12˚C – 30˚C).
    NOTE: The fan speed is shifted automatically between low, medium, and high fan speed to maintain the room temperature.
    Once the room temperature exceeds the selected setting by approx. 4˚F (2˚C), the Fan will automatically stop.

MANUAL FAN OPERATION

  1. Press the Power switch. The power lamp will light and the current room temperature and the set temperature will be shown on the digital display. If the unit is set .. Manual Fan mode, “MANUAL” is shown on the digital display.
    If “AUTO” is shown on the digital display, press the AUTO FAN/MANUAL FAN button to switch to the manual mode.

    NOTE: The room temperature is not controlled during the Manual Fan mode. The fan speed will stay in the set fan mode regardless of room temperature.

TIMER OPERATION
“ TIMER ” operation is programmed for a particular clock and temperature, in arrange to save energy when the unit is used for model at night or while you are aside from home.
NOTE: Meaning the timer feature allows a exploiter to automatically change the temperature ( set by exploiter ) until a certain time of day ( set by exploiter ) by pressing the Timer release. This clitoris must be pushed each time you want the temperature to go to a unlike temperature. It does not mechanically start.
“ TIMER OPERATION ” is not available in Manual Fan mode

Example:
Your normal room temperature is set for 70 degrees. You work from 8 am until 5 pm. You want the room temperature to drop to 62 degrees while you are at exercise and you want the room to return to 70 degrees at 4 pm so it will be warmly when you get home. When you leave for work you must press the timer button to activate the timer. The temperature will drop to 62 degrees and restitution to 70 degrees at 4 promethium. Setting Timer:

  1. Make sure the clock is set. If not, press the hour and minute button until the correct time is indicated.
  2. Press the Timer button. The Timer lamp will flash. Use the “–/hour” and “+/min.” buttons to set the time at which you want the room to return to normal temperature. This would be 4:00 PM to have the room start heating up at 4 pm. You have ten seconds from the time you push the button to start entering this setting.
  3. After ten seconds of not pressing the “–/hour” or “+/min” button, the display will change to temperature. The display will show 68 degrees by default. Use the “–/hour” or “+/min” button to adjust the temperature setting, in this case to the desired 62 degrees. The timer is now set and you are in the timer mode. To return to the normal operation mode, press the Timer button again to turn it off.
  4. If the unit has been set for a particular hour and the temperature of the timer operation while in shutdown, the time lamp will change from flashing to continuous and the timer time will be shown on the digital display after completion of setting the timer. To start the timer operation Press the Power switch to turn on and then press the Timer button. The Timer lamp will light and the timer operation will start.
    NOTE: The unit operates at the same hour and at the same temperature if it has once been set for such an hour and temperature.
    NOTE: If at any time a power failure occurs the time and temperature settings are canceled.
    NOTE: To cancel the timer operation, press the Timer button again. The Time lamp will go out. Normal operation will then be restored.
    NOTE: After the unit has been set for a particular hour and temperature it will operate at that same time and temperature when the timer button is turned on.
    NOTE: To change the setting on the timer, during timer operation, press the “–/hour” or “+/min.” button to change the timer setting in the same way as 2. under “Setting Timer”.

CHILD LOCK OPERATION
