Instructions for use:

The module is powered by a stable 12 V DC source. The power pins are made through the screw terminals marked "+12 V" and "GND". Unlike a regular relay, it has only two terminals "K0" and "K1". When the sensor reaches a certain temperature, "K0" and "K1" are either connected or disconnected, depending on the module configuration.

There is an LED on the module to indicate the status of the relay (switched on or off). When the LED is lit, the relay is switched on so that "K0" and "K1" are connected. Otherwise, the relay is disconnected so that "K0" and "K1" are disconnected. This LED is useful to know if the relay is switching on properly, depending on the configuration chosen.

Connect the temperature sensor.

If the module is powered on and the temperature sensor is not connected, an error message "LLL" appears on the segment screen. The error message automatically disappears when you connect the sensor.

Set the trigger temperature.

To set the trigger temperature, you must press the "SET" button and then use the buttons marked with "+" and "-" to increase or decrease the trigger temperature, respectively. The setting step is 0.1 ° C. Once you have selected the desired temperature, you must press the "SET" button again to confirm the selected temperature.

Configuring operating parameters.

The module has 6 operating parameters, which you can change by holding down the "SET" button for 5 seconds. The code of the parameter selected to be changed will appear on the screen, (from "P0" to "P6"):

  • "P0": The first parameter can be set to "C" or "H". When "C" is set, the relay will switch on when the set temperature is lower than the temperature measured by the sensor. This mode is useful in creating an air conditioner. When "H" is set, the relay will switch on when the set temperature is higher than the ambient temperature, being useful in the construction of a heater.
  • "P1": The second parameter is the deactivation threshold. For example, if "P1" is set to 2 ° C and "P0" is "H", then the relay will switch off when the set temperature is 2 ° C lower than the temperature measured by the sensor.
  • "P2": Represents the maximum setting temperature limit, which is a way of protection against accidental setting of a temperature that is too high.
  • "P3": Represents the minimum setting temperature limit, which is a way of protection against accidental setting of a temperature that is too low.
  • "P4": This parameter represents an offset value (with a step of 0.1 ° C), being useful to correct the measurement errors of the sensor.
  • "P5": The 5th parameter is the relay trigger delay time, the step being 1 minute.
  • "P6": The last parameter is useful to switch off the automatic relay when the temperature measured by the sensor exceeds the value represented by parameter 6. The text "---" will also be displayed on the screen.

Possible values of the configuration parameters:

  • "P0": C / H;
  • "P1": 0.1-15 ° C;
  • "P2": -45 ° C - + 110 ° C;
  • "P3": -50 ° C - + 105 ° C;
  • "P4": -7 ° C - +7 ° C;
  • "P5": 0 - 10 minutes;
  • "P6": ON (0 ° C - 110 ° C) or OFF;
