1,The factory default temperature value of time interval 3 and 4 are the same as period 2,please modify
default temperature when it’s necessary.
2,Setting temperature is“00”, this time interval is shutdown.
3,View out temperature value (floor temperature)
(1)Touch screen version(HY03WE,HY03WW series):when internal control temperature and external limit temperature(high
temperature protection),under power on state,press time key not move first,then press on/off key together to switch and view
external temperature (this time measure temperature display zone displays OUT TEMP temperature value),press time key to
display room temperature;
(2)Button version(HY-2B03H,HY-02B07H,HY-02B09H series):when internal control temperature and external limit
temperature (high temperature protection),under power on state,press mode key not move first,then press on/off key together
to switch and view external temperature (this time measure temperature display zone displays OUT TEMP temperature
value),press mode key to display room temperature;

Advanced Setting(suggestion:operated by technician)

(1)Touch screen version(HY03WE,HY03WW series):under power off state,first press not move,then press together
enter into advanced setting,it will save after backlight is out,press to set next data

external sensor limit temperature hysteresis(dIF) set as 2,when temperature up to 44℃,relay stop output,when temperature

drops to 40℃,relay output again and heating.(operation when room temperature lower than setting temperature)

Sensor fault hint

Please select internal,external sensor working mode correctly.If it is choose wrong or sensor is fault (breakdown),LCD
interface will display“Err”,temperature controller stops heating until fault is eliminated. Special Hint:installation cable

Please select:water heating selects 1.5-2.5mm2 rigid line;electric heating select above 2.5mm2 rigid line.
