Five, button and function description

1. host buttons:
Host four buttons were "switch (S1), set (S2)",
"+ (S3)" and "- (S4)""
2. remote control button:
The five keys of the remote controller are "switch", "setting" (function), "+", "-" and "automatic"".
3. open, key:
After switching on the power, press the "switch" button once: the machine will follow the last set of working mode to start the work. Under the working state press the switch button once: shutdown stop working.
4. set the (function) key:
During the setting process with "+" and "-" button; press the set button (function), if 3 seconds without any key operation, save the settings and return; in the boot state long press "set (function)" button 2 seconds later (at the same time there will be a "tick" sound continuous ringing two times) to the clock and timer switch machine set.
5.+, - bond:
With the "settings (function)" key used; in the boot state, if directly press "+" and "-" key, adjust the current period of setting temperature is high and low.
6. timing on and off time:
If the timing of opening and closing time is set at the same time to open, there is no shutdown function.
When the clock is running to the set time, if the machine will automatically boot in standby state; the machine is not executed under the boot state. When the clock runs to the set timing shutdown time, if the system is in the state of automatic shutdown, the system is not executed under the shutdown state.
7. water temperature and room temperature:
The temperature control of temperature, when the water temperature reaches the set temperature to stop heating, insulation (insulation) when the actual temperature reaches the set temperature of -5 DEG C when re heating; just do not show room temperature, water temperature and room temperature control; turn display.
8. Over temperature protection:
When the temperature of the liner or coil exceeds 125 degrees, the machine automatically stops heating and restores automatically when the temperature of the inner liner or coil is lower than 125 degrees.
9. Slope dry burning protection:
When the temperature of the inner liner or coil is increased by more than 3 degrees in 3 seconds, it is judged that the inner liner is dry, the machine stops heating automatically, the temperature rise slope is returned to normal, and the machine automatically returns to normal work.
10. Low temperature anti icing protection:
Water temperature is less than 5 degrees, the machine does not need to start the system automatically start work, water temperature heating to 10 degrees, the machine insulation at this temperature point.

Setting instructions
An ordinary operation (this is suitable for simple operation)
1. press the "switch" key machine to default the most high-grade power, to the last set of water temperature work;
2. according to the function keys can set the power stalls and set the water temperature (with the "+" - "-" key to achieve the set);

Two, advanced operation
1. click "switch" button, the machine starts to work; long press "set (function)" button for 3 seconds will be "beep" twice to enter the following advanced settings:
1.1 clock setting
1.2 gear selection (1-3 files optional; 1 files 1 main board work; 2 files 2 main board work; 3 files 3 main board work); this function 8-12KW practical
1.3 timing set, shutdown settings (the machine can be set according to the needs of one to three periods of time to open, shut down; three periods can not cross, between the time interval and the time interval should be set at least 1 minutes;
The water temperature setting in the first period is the starting time of the first period and the first stopping time
Second time water temperature setting: second time interval start time, second time shutdown time
Third time water temperature setting: third time interval start time, third time shutdown time
2. long press "set (function)" button to return to the default boot state clock;
3. long press "-" key 3 seconds into the automatic state, at this time, except the key, the rest of the key failure,
The machine according to the set time automatically.

Examples of timing on / off operation:
For example: 8:00 in the morning began to boot to the 12:00 shutdown, the water temperature is 60 DEG C (the first time); at 14:00 17:00 to boot shutdown, the water temperature is 40 C (second hours); at 19:00 00:00 to boot shutdown, the water temperature is 50 C (third hours); is set according to the following steps:
Step 1: click the "switch" button, the machine starts to work
Step II: long press "set (function)" button for 3 seconds (there will be a "beep" twice) into the clock calibration (at the top left corner of the screen will flash, digital time) according to the "+" and "-" to adjust the time for the local time (according to the "+" to adjust the clock, press "- to adjust the minutes)
Step 3: press "set (function)" button once to enter the setting temperature (at the upper right corner of screen will flash, digital) according to the "+" and "-" to adjust the temperature of 60 DEG C (press "+" to increase the temperature, press "-" to reduce the temperature)
Step 4: click "settings (function)" button once to enter the first time start time (at the top left corner of the screen will flash digital time at the same time, the lower left corner of the "timing" bright), according to the "+" and "-" the adjustment time is 8:00
Step 5: press "set (function)" button once to enter the first period of time off (at the top left corner of the screen will flash digital time at the same time, the lower left corner of "time off" bright), according to the "+" and "-" the adjustment time is 12:00; 3, 4, 5, repeat steps second times and the third time set set; after a pause for three seconds according to "switch" button once to return to the standby state, long press "-" key to enter the automatic state.
If you only set two time interval timer, the switch time of the third time is set at the same time point (this time point should be greater than the shutdown time of second periods)

Three, pay attention to:
1. electromagnetic heating device (water heater) is from the bottom of the water, above the water, in the water should be paid special attention to prevent water bile partial dry burning;
2. pay attention to the installation of the inlet and outlet can not be blocked by other items, maintain a good ventilation state, in order to long-term stable work.
