Management (various)
6.15.1 Single or distinct Set Point
It is possible to manage a single regulation Set Point for summer/winter, or to set two
different ones. If the parameter PH27 Enables the single/distinct Set Point is set to 1 the Set
Point is singular (only one parameter), otherwise the Set Point is distinct (two distinct
parameters: SEtH and SEtC).
In the case of a single Set Point (PH27= 1) the parameter SEtC (summer Set Point), is no
longer valid and the single regulation Set Point becomes the SEtH which no longer assumes
the value of a single winter set but instead that of a single regulation Set Point for the
summer/winter.
6.15.2 Compensation for Set Point
Only during summer operating mode (parameter MOdE=0=CooL), the cooling regulation
requests a compensation for the regulation ambient temperature Set Point to function with the
external temperature (parameter PC01 to enable the function). The function is important to
avoid an accessive jump in thermal temperature between the external and internal ambient
temperatures and ensures adequate comfort under mutual conditions. Furthermore, this
allows for energy savings on the implant.
The compensation Set Point increases proportionally with the increase in external
temperature until it reaches the maximum admissible set configured at parameter PC02.
Note. To utilize this function it is necessary to enable the external temperature probe and set
the parameter PH40 to 1. When the external probe is in error this function is inhibited.
6.15.3 Variation Set Point from Digital inputs
The program provides the possibility to manage a parameter OS01 Offset Set Point from DI
which, based on the status of the Digital inputs, provides a sum at the regulation Set Point. It
