XH-W1321 DC 12V Digital LED Temperature Thermostat Controller 10

Description:
XH-W1321 use ST controller and high-precision temperature sensor probe.Good performance and accuracy.Simple panel control, wide temperature range, simple design, 1.8mm ABS shell, elegant appearance, high mechanical strength. It can be embedded industrial equipment, convenient and fast. It can be used for hatch control, equipment cabinet, air conditioning system, temperature control protection, etc.

Features:
1>. Supports heating mode and cooling mode.
2>. High precision 0.1 Celsius.
3>. Power-down memory function.
4>. Custom load, arbitrarily selected.
5>. Simple setting.
6>. Easy installation.

Parameters:

Key Description:
1>. ‘Set’ key: Short press to set stop temperature;Long press enter into internal menu to set parameter P0-P3.(Long press is for 3second).
2>. ‘Up’ key: Increase parameter value or select mode.
3>. ‘Down’ key: Decrease parameter value or select mode.

Menu Description:
Long press enter into internal menu to set parameter P0-P3.

P0 : Set Work Mode .For first time use, this parameter must be set. If applied to warm up and heating, set the parameter to H.If applied to Cooling, set the parameter to C.(NOTE : ‘H’ means hot; ‘C’ means cold)
P1 : Set Return Temperature. Long Press ‘Set’ key for 3second enter to menu to select P1 and short press ‘Set’ again to set value by other two keys.Return Temperature is the value that module re-output when reach stop temperature. For example: If we select Heating mode.Temperature rises to 40Celsius to stop heating.Temperature will slowly drop.We have set stop temperature is 35Celsius.It will reheat when the temperature is lower 35Celsius.So the Return Temperature is 5Celsius.
P2 : Set Temperature Correction. Long Press ‘Set’ key for 3second enter to menu to select P2 and short press ‘Set’ again to set value by other two keys. For example: The Temperature Correction need be set to -0.5Celsius if measuring temperature is 0.5Celsius higher than Actual temperature value.The Temperature Correction need be set to 1Celsius if measuring temperature is 1Celsius lower than Actual temperature value.Measuring temperature +/- Temperature Correction =Actual temperature.
P3 : Delay Start. Long Press ‘Set’ key for 3second enter to menu to select P2 and short press ‘Set’ again to set value by other two keys.Delay Start is generally used for compressor refrigeration. Otherwise you can not set this parameter. For example: You need set this value if use it in refrigerator or freezer.The parameter is set to 3-6minutes usually.

Instructions:
1>. Set Return Temperature. Why set Return Temperature? Temperature will rebound or drop back when control equipment and stop heating or cooling.How much change in temperature can make the device work again?If you want the temperature to change by 10Celsius, the equipment work again.It need you to set the Return Temperature at 10Celsius.The device work cycles in this temperature range by setting Return Temperature.
2>. Set Stop Temperature. Short press ‘Set’ key and then the screen will flashing.Set value by other two keys.
3>. How to restore factory settings? Press two key ‘Down’ and ‘Up’ at the same time,When display ‘888’ and then display current temperature.It means restore factory settings successfully.

4>. Heating mode setting.
Focus: Step 1 set P0=H;Step 2 set stop temperature;Step 3 set Return Temperature.
Method:
1). Long press ‘Set’ enter to menu and set P0=H;
2). Short press ‘Set’ to set Stop Temperature;
3). Long press ‘Set’ enter to menu and set Return Temperature P1.
For example: Control water heater.Heated to 65Celsius and then stop heating.Reheat when the temperature drops to 50Celsius.
1). Long press ‘Set’ enter to menu and set P0=H.Make sure is Heating mode;
2). Short press ‘Set’ to set Stop Temperature to 50Celsius ;
3). 65Celsius stop heating and 50Celsuis reheat and so Return Temperature is 65-50=15.Long press ‘Set’ enter to menu and set Return Temperature P1=15.

5>. Cooling mode setting:
Focus: Step 1 set P0=C;Step 2 set stop temperature;Step 3 set Return Temperature.
Method:
1). Long press ‘Set’ enter to menu and set P0=C;
2). Short press ‘Set’ to set Stop Temperature;
3). Long press ‘Set’ enter to menu and set Return Temperature P1.
For example: Control farms. Stop ventilation when temperature is 26Celsius.Refrigeration again when the temperature rises to 28Celsius.
1). Long press ‘Set’ enter to menu and set P0=C.Make sure is Cooling mode;
2). Short press ‘Set’ to set Stop Temperature to 28Celsius ;
3). 26Celsius stop cooling and 28Celsuis refrigeration and so Return Temperature is 28-26=2.Long press ‘Set’ enter to menu and set Return Temperature P1=2.
