W3230 Mini Digital Temperature Controller LED Display Thermostat Regulator AC110V-220V OR DC 12V 20A
W3230 Mini Digital Temperature Controller LED Display Thermostat Regulator AC110V-220V 20A 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 terminal “”K0 / K1″” for connecting the load and “”VCC / GND”” for powering the Thermo controller 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.
| Parameter code | Parameter description | Setting range | Default |
| P0 | Thermostat operating mode: Cooling / Heating | C / N | FROM |
| Р1 | Hysteresis ° С | 0.1 … 15 | 2 |
| P2 | The upper limit of the maintained temperature setting ° С | 120 | 110 |
| P3 | The lower limit for setting the maintained temperature ° С | -fifty | -fifty |
| P4 | Temperature correction ° С | -7 … + 7 | 0 |
| P5 | Delay of relay activation time (may differ from the selected one within ± 50%) min. | 0 … 10 | 0 |
| P6 | Upper limit of shutdown temperature (overheating protection) ° С | OFF or ON (at ON from 0 ° С to 110 ° С) | OFF |
| P7 | Locking settings | OFF or ON (when ON you cannot change the settings until you set P7 to OFF) | OFF |
| P8 | Restoring factory settings | OFF or ON | OFF |
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.
