Only if the system is heating or cooling, rEL.C displays.
In the process of PID self-setting, the system can only set ProP, ln とと and dEr と. The
cooling parameter rEL.C should be set by hand.
If the adjust method is set at positioning adjustment, ProP is the difference of positioning
adjustment.
When Pbd is set at C-F, the unit of ProP is Celsius or Fahrenheit; when Pbd is set at Pct, the unit
of ProP is %, and then the heating area equals ProP multiplied by the heating proportion coefficient
PH-L. The greater the cooling coefficient, the greater the cooling output power. The cooling output
power equals the temperature difference divided by heating proportion,then mutiplied by cooling
coefficient.
Control mode parameter Rc と
When Rc と is set at rEu, the control mode is reverse-acting control. It means that as the input
signal of the meter increases, the adjustment output decreases. For example, in heating control
system, when the temperature rises, the output heating power should decrease, so we choose
reverse-acting control.
When Rc と is set at rEu, the control mode is positive-acting control. It means that as the input
signal of the meter increases, the adjustment output increases. For example, in heating control
system, when the temperature rises, the output heating power should increase, so we choose
positive-acting control.
