DVP02TUR/DVP02TUN-S/DVP02TKR/DVP02TKN-S series, every channel has 2 digital outputs. Outputs control the
ON/OFF mode.

Actions for the heating output:
The output is OFF, when the input is greater than the setting value. Output is ON, when the input is smaller than the total
value of the setting value + adjustment sensitivity setting value. For example, set the setting value to 100 degree and the
heating sensitivity adjustment to 10 degree; when the temperature reached 100 degree, the digital output switches to OFF.
When the temperature is 90 degree, it will heat up to 100 degree, and then the digital output will switch to OFF.

Actions for the cooling output:
The output is ON, when the input is greater than the total value of the setting value + adjustment sensitivity setting value.
Output is OFF, when the input is smaller than the setting value. For example, set the setting value to 10 degree and the
cooling sensitivity adjustment to 5 degree; when the temperature reached 10 degree, the digital output switches to OFF.
When the temperature is 15, it will cool down to 10 degree, and then the digital output will switch to OFF.

Actions for dual outputs:
When setting one output for heating and the other for cooling, a non-action zone (dead band) can be set as below. For
example, set the setting value to 100 degree, heating sensitivity adjustment to 10 degree, cooling sensitivity adjustment
to 5 degree and dead band to 20 degree; when the temperature is 90~100 degree, the outputs will be OFF. Heating up
the temperature to 90 degree, the output will switch to OFF. When the temperature is below 80 degree, the heating up will
be started. Cooling down the temperature to 110 degree, the output will switch to OFF. When the temperature is over 115
degree, the cooling will be started.
