Application Examples:
Connect the circuit as shown below:
In this application examples, the fan will be switched 'On' when the temperature reached the limit set by the
user. The fan will be switched 'Off' when the temperature cool down to the normal temperature. In this case,
the fan is supply from same power supply as module, limited to maximum of 12V.
1. Press 'SET' button once to set the desired control temperature, i.e. 33°C.
2. Make sure the P0: Cooling or heating parameter
3. Try pressing the sensor for few second, the temperature will goes up. Once it reached 33°C, the fan
will switch 'On'.
4. Release the hand from the sensor, the temperature will slowly goes down. Once it reached the
temperature 2°C (hysteresis default setting) below the set temperature, i.e. 33-2= 31°C, the fan will
switch 'Off".
5. You can change the 2°C Hysteresis setting to other value. Refer to "Parameter Setting" on how to
change this setting on P1: Hysteresis parameter.

is set to 'C' for cooling.
