With r.c.r = relative gain of cool action from 0.1 to 3.0 Example:
if Pb heat = 10% and r.c.r =0.5 Pb cool = 20% The ti (integral) and td (derivative) times of Heat are
valid also for Cool whereas the cycling times tc are different.

Note:
1 For mA and Volt inputs the beginning and end scale values can be configured in
engineering units between -999 and 9999.
The minimum scale span is of 100 steps.
The values can be expressed in units (xxxx), in tenths (xxx.x), hundredths (xx.xx)
or thousandths (x.xxx).
2 The safety value assumed by Y1 and Y2 (if configured heat-cool) in case of failure
in the control loop coincides respectively with the upper limit of Yh and Yh2.
