W3230 Mini Digital Temperature Controller LED Display Thermostat Regulator AC110V-220V 20A Temperature Control Switch Sensor Meter

The programmable thermostat model W3230 is designed to control temperatures in the range from -50 ° C to + 120 ° C. It can be paired with a heater or cooler. The programmable thermostat is equipped with two three-digit LED displays an LED indicator for switching on the relay three control buttons + a power button connected to an external temperature sensor terminals ""K0 / K1"" for connecting the load and ""VCC / GND"" for powering the thermocontroller module (110-220V AC). The current measured temperature is shown on the LED display.

Preparation for work:

• Connect a 110-220 VAC power supply to the VCC and GND pins.
• Connect  the load control through the contacts ""S0"" and ""S1"" (connected to the open circuit of the controlled device power supply (serial connection))
• After energizing the contacts ""VCC"" and ""GND"" the LED display will show the current temperature measured by the external temperature sensor.
• Setting and adjusting the set temperature
• To set the control temperature shortly press the ""SET"" button then use the ""+"" or ""-"" buttons to set the preset temperature and press the ""SET"" button again or do not press any buttons for 5 seconds.
•  Programming
• To enter the programming mode hold down the ""SET"" button for 5 seconds then use the ""+"" or ""-"" buttons to select the menu parameter code (P0 ... P) from the ""Temperature regulator menu"" table. Further to adjust the parameter press the ""SET"" button and use the ""+"" or ""-"" buttons to change the parameter value. To save the settings press and hold the ""SET"" button or do not press any buttons for 5 seconds.

Indication:

 LED display shows the following values: ""LLL"" - sensor not connected ""HHN"" - temperature out of range (less than -50 ° C or more than 120 ° C) ""---"" exceeding the limits set in parameter P6

 Resetting parameters to factory settings

 To reset parameters to factory settings (default settings):

1) turn off the power;

2) press and hold the ""+"" and ""-"" buttons;

3) Apply power to the thermostat.

The LED display will show “888” after which the current temperature will be displayed.
