1. Input:

220V / 50Hz utility.

the power cord access, after the power switch (external), fuse (external) after entering the power control panel, via thermistors, safety capacitance until the transformer, step-down, rectifier, filtering after use. Lord panel output 5V.

temperature sensor 1, connect radiators backwater place, test the return water temperature.

level sensor 1, which is used to detect heating heating films of water; Below is the warning level sensor switched on, hydrating electromagnetic valve opens, automatic filling water.

temperature sensor 2, then wash bath water heating slice, water temperature detection place.

level sensor 2, which is used to detect bath heating water, below the warning level film sensors connected, the system is acousto-optic alarm, feed valve closed remind tap water or damaged.

potentiometer, VR1 backlight brightness of fine-tuning.

leakage current transformer, used to detect leakage current.

315MHz wireless receiving module, for receiving 6 button on the remote control signal.

2. Output:

heating heating tablets, 2KW a group, three groups, with three relay control, applicable three gears,

bath heating tablets, 2KW a group, three groups, with three relay control, applicable three gears,

circulating pump, one 220V / 1KW; Use a relay control,

hydrating electromagnetic valve, one 220V / 40 w, is used in the automatic filling water,

pen LCD panel and used for KNN interface display;

3. Basic function:

 pre-splitting heating function, when the return water temperature below 3 degrees, this function startup, heating slice heated to a backwater higher temperatures than 10 degrees, heating slice stop.

winter/summer mode, summer mode is heating heating plate and circulating pump is not running, only keep bath heating function; Winter heating mode is bath function and heating heating functions are all startup.

prevent leakage function, detect leakage current, the 15mA > in 0.1 seconds automatically cut off power supply.

prevent dry burn (automatic filling water) function, below the warning level will automatically filling water.

 prevent dry heating function, bath heating tablets, below the warning level is audible and visual alarm.

 multiple functions, Within a set period, each time more than can be set up different control temperature.
