Parameters concerning the set-point

St1: Set-point 1 (main)
St1 is the most important parameter; it is used in any operating mode, except in SLAVE.

Operating range:
Default: St1=0.0.
St2: Set-point 2 (secondary)
St2 can be used alternatively to St1 in those operating modes based on the presence of St2.

P01: Differential of St1
P01 defines the hysteresis of St1 (that is the width of the regulation zone). It is a relative value which can have the same value as St1 or
can be set on its right or on its left.
