6.20 Management (various)
6.20.1 Single or distinct set point
It is possible to manage a single control 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In the case of a unique Set point (PH27= 1) the parameter SEtC (summer Set point), is no longer valid and the
unique control Set point becomes the SEtH which no longer assumes the value of a single winter set but instead that
of a single control Set point for the summer/winter.
6.20.2 Compensation for set point
Only during summer operating mode (parameter MOdE=0=CooL), the cooling control requests a compensation for the
control room temperature Set point to function with the external temperature (parameter PC01 to enable the
function). The function is important to avoid an excessive jump in thermal temperature between the external and
internal room temperatures and ensures adequate comfort under mutual conditions. Furthermore, this allows for
energy savings on the plant.
The compensation Set point increases proportionally with the increase in outdoor air temperature until it reaches the
maximum admissible set configured at parameter PC02.
Note: in order to utilize this function it is necessary to enable the room humidity sensor, setting parameter PH40 to 1.
This function is inhibited with the external probe in error mode.
