Functions and Operation.

Temperature:

The LCD will display the temperature measured by the temperature sensor in the range of 6℃-60℃ (43℉-140℉).

Set temperature:

The temperature setting range is 35℃-55℃ (95℉-131℉) and indicated by the 5 red LED’s next to the LCD.

Set time:

The maximum setting time is 60 minute. The default working time is 45 minutes. If the system is in long-term working mode, the LCD will display CH.

The bottom LED is on when temperature is 35℃ (95℉).

Hint Message:

1) Temperature is lower than 6℃ (43℉): LCD displays “-L”, detected by the temperature sensor.

2) Temperature is higher than 60℃ (140℉): LCD displays “-H”, detected by the temperature sensor, all heating elements will stop working.

3) Water supply fault: LCD displays “- E”. This message appears when the water level is lower than the minimum water level required 10 minutes after the system has started and the water inlet valve is open, or the water level is lower than the desired level 3 minute after the water supplementing order has been given. It indicates faults with the water supply system, all heating elements will stop working.

4) Drainage: LCD displays “dd”, indicates automatic draining after the steam cycle has been or is being completed (ON/OFF button is pressed or setting time is up), then the whole system will shut down automatically.

5) Connection error: LCD displays “EE” showing any connection error between the controller and the main PCB.

6) Heating up: indicated by the white LED on the left of the panel with label “         ’’.

Sequential Heating function:
a) Has two groups of heating elements (1~6 elements): if actual temperature is below the setting value then both two groups of heating elements are working; if the actual temperature is 2℃ (4℉) higher than the setting value so only one group of heating elements is working.

b) Has three groups of heating elements (9 elements): if the actual temperature is below the setting value of more than 2℃ (4℉) then all three groups of heating elements are working; if the actual temperature is less than 2℃ (4℉) lower than the setting value, then two groups of heating elements are working; if the actual temperature is 2℃ (4℉) higher than the setting value, then only one group of elements is working.

7) Insulation: indicated by the white LED on the right of the panel with label “         ”. If the current temperature is more than 2℃ (4℉) above the setting temperature, all heating elements will stop working and the system will be under insulation function.

 
 

Buttons Operation

ON/OFF:
Press                  to switch on and off the generator system. Pressing this button will switch the generator on and open the water inlet solenoid valve allowing the generator to fill with water. When the water level reaches the required water level, the system begins to heat up (if current temperature is lower than setting temperature).

Once the water level reaches its maximum level, the inlet valve closes and the system enters the automatic working process. If the system is shut off by pressing ON/OFF button, system will adapt the default temperature and time setting; otherwise if the system is shut off automatically when setting time is up, system will adapt the previous temperature and time setting.

The system then begins to heat up and produce steam after several minutes. Pressing the ON/OFF button again will shut down the system manually and the system will drain automatically.

SET:
Temperature and Time setting button. Press                 to adjust the temperature. The LCD and the white LED on the left will blink and display the previous setting temperature.

If the system has been turned off and restarted, the LCD displays the default temperature 43℃ (109℉) then press the “▲” or “▼” buttons to adjust.

Press                  to adjust the working time.

The previous setting time or the default setting time of 45 minutes if the system has been turned off and restarted, or the remaining working time (during working time)
You could set the working time by pressing “▲” or “▼” button to adjust the working time to the value you want, or press “▲” button until the LCD displays “CH”, after that the system automatically enters long-term working mode.

The available temperature range is 35℃～55℃ (95℉～131℉) and the default temperature is 43℃ (109℉). When the system is in long-term mode, the white LED on the right side of the LCD blinks. When the working time is set, the maximum working time is 60 minutes and the default working time is 45 minutes.

LIGHT:
Press                  switch for the external light. The button can be used as the switch for the external light as long as the system is connected to power supply. The LED is on when the light is turned on.
▲ Increase the temperature or time.
▼ Decrease the temperature or time.

 
 

Auto Functions

Auto filling:
inlet valve will open automatically once the system is started and fill with water automatically until the water level reaches maximum level. If water level is lower than the minimum water level 10 minutes after, it indicates a fault with the water supply system and all heating elements will stop working and the LCD will display “-E”.

Auto heating up by sections:
generator will compare the measured room temperature with the setting temperature and then decides the number of working heating elements required.

Auto water supplementing:
if the water level is lower than the desired level when operating, auto water supplementing function will turn on and open the inlet valve. Once the water level reaches the desired level, auto water supplementing function will turn off. If water level is lower than the required level 3 minute after the water supplementing order is given, it will indicate a fault with the water supply system and all heating elements will stop working and the LCD displays “-E”.

Auto drainage:
when steam cycle time is over or ON/OFF button is pressed, system will drain automatically and display ‘dd” on the LCD. The drainage valve will be turned on to drain. After a while the system will open the inlet valve to re-fill the tanks in order to flush and cool down the inner tanks and heating elements. The whole process takes a few minutes, and the system will be shut off automatically once completed.
