CLIMATIC COMPENSATION
It is possible to compensate the set‐point according to outdoor temperature, in a different way between heating and cooling modes,
first and second set‐point.
In such a case be sure that the b08 parameter (System main page ‐> Configuration ‐> Service menu ‐> Parameters ‐> Chiller ‐> Chiller
name ‐> b08: Enab. dynamic set point) is disabled (=0) on the chiller.
