Code and function introduction

PO setting to start-up temperature

Press setting button enter into internal menu.Default setting

displayed "PO" ,then press the setting button again,set temperatureby press the upand down buttons.

P1 setting to stop temperature

Press the setting button enter into the internal menu,digitaldisplayed "PO",change it into "Pl" by press up and down buttonsthen press the setting button again.Stopped temperature by pressthe up and down buttons.

P2 setting to correct the temperature

Enter the internal menu in the same way, switch to P2 by pressing upand down, press the Set button again, and set the required calibration temperature by pressing up and down. (Note: In thesetting, if the detected temperature value is 0.5℃ higher than theactual temperature value, the calibration temperature to be set is-0.5℃. lf the measured value is 1℃ lower than the actual temperature, the calibration temperature needs to be set to 1℃.Detection temperature + calibration temperature = actual temperature.

P3 Set delayed start

Press the setting button enter into the internal menu,switching intoP3 by pressed the up and down button.Then press the setting

button again and set delayed time(Unit: minute)by pressing up anddown button. (Note: The function delay to start is used to

compressor refrigeration.lt need to set value if use to refrigeratorfreezer.Usually it set to 3-6 minutes according to the backreturn sizeof compressor.lf it is not use to compressor or no need this delaytime function just skip this item.)

Heating Mode Setting

Main points of Setting,start-up temperature<stop temperature(producer automatic judging the heating mode)

setting mode:Press settingbutton enter into the internal menu,started-up temperature by setting value of“PO" ,stop temperatureby setting value of "PI" .

Use case:

Control water heater,stopped the temperature when heating up to50°C.restart the heating when temperature fall back to 40°℃.Theinstruction as follow,

STEP 1:Make sure the mode of work is heating,start-up temperature<stop temperature.

STEP 2:Press the setting button enter into the interna menu,choose“PO"and press setting button to set value of "PO" to 40°℃.

STEP 3:Press the setting button enter into the interna menu,choose"Pl" and press setting button to set value of "P1" to 50℃.

Cooling Mode Setting

Main point of setting:Start-up temperature>Stop temperature(producer automatic judging the cooling mode)

setting mode:Press setting button enter into the internal menu,started-up the temperature by setting value of "PO”,stop

temperature bv settina value of "PI”

Use case:

Control the cabinet radiator,stop working at heat dissipation 26℃.Starting radiator when temperature come back 30°C.The instructionas follow,

STEP 1:Make sure the work modeis cooling,started-up temperature>stop temperature.

STEP 2:Press the setting button enter into the internal menu,choose“PO" and press the setting button to set value of “PO" at 30°℃.STEP 3:Press the setting button enter into the internal menu to setvalue of "PI at 26℃.

Examples of use

Using an examplel want to control the temperature of the chickshatch in 37.5 ℃~38C, how to set?

. Short press the set key screen PO,short press the set key again

shows the current start temperature,press the up/down key to adjuststart temperature of 37.5 ℃.(5s without operation automatic saveand exit)

- Short press set key Po screen display,press the switch to P1,shortpress the set key again shows the current stop temperature,pressthe up/down key to adjust stop temperature for 38℃.

. Set up,the thermostat will be 37.5 C control heating equipmentfor heating,temperature rise to 38 ℃ stops,the temperature droppedto 37.5 Cuntil heating cycle again.

I actually measuring temperature 35 C,temperature controlleraccording to 35.6 °℃,how to calibrate?

. Short press set key PO screen display,press the switch to P2,pressthe set key again shows the current temperature calibration,pressthe up/down key to adjust the calibration of -0.6 ℃ can.(thermostatshows temperature is greater than the actual measuring temperature0.6 ℃)

Common Fault

lf user accidentally set the temperature value upside down,the inputlight will bit bright and the load not work,if in this situation.Pleasecheck whether the value of setting temperature have been upsidedown.

Factory setting solution

· Hold down the up key and press down until the screen displays 888to restore factory Settings.

·LLL on the screen indicates that the temperature probe is notinserted, disconnected, or damaged.Replace it.

·lf HHH is displayed, the temperature probe is short-circuited andexceeds the temperature detection range.
