calculated integral value is used. See p6 for graphic example.
If ot.Ar is selected, then proportional band is used in PID process instead of Ar
value.

Derivative time for heating (0.0 to 999.9 seconds)
Ct-H
Control period for heating (1 to 150 seconds)
For Relay module: 30 seconds

Ct-H
or 50 miliseconds when = 0.0)
CCoE
Cooling proportional band coefficient. (0.0% to 100.0%). If heating and cooling
PID are used, tunning is performed by the heating output. Therefore (

CCoE
/100) eg. If P-Ht=10.0% and CCoE=50 then P-CL=
10.0*50/100=5.0%. If value is 0.0, coefficient is inactive.
Recommendation: CCoE=100 when cooling with air; 80 with oil; 40 with water

d-CL
Derivative time for cooling. (0.0 to 999.9 seconds)

Cooling control period. (1 to 150 second)
Recommendation: Use an SSR output for control periods shorter than 30s.
These are much better suited for frequent on/off operation than relay outputs.
