6.3 Double set point by digital input (optional)
The double set point function (Energy Saving) allows to modify the regulation parameters via digital
input (terminals 1­60).
The Energy saving function is enabled when a digital input configured as “Energy saving” is active.
When the Energy Saving function is active:
• to the set point is applied an offset set by ES14 and ES16 parameters
(different for cooling andheating);
• the regulation differential is set by ES15 and ES17 ;
standard differentials ( St07 and St08 parameters) are not used if the Energy Saving is active
If the Energy saving is active, the first pressure of button allows to read the set point set by
parameter and second pressure allows to read the real set point (label Setr set ­ modified by
Energy saving finction).
6.4 Compensation of the set point based on the outside temperature (optional)
The controller allows the working set point of the unit to be changed (compensated) automatically
based on the outside air temperature measured by a probe installed on the machine.The summer set
point and the winter set point can be compensated separately, whereas it is not possible to
compensate the domestic hot water set point.For the settings of the dynamic set point, parameters
Sd01 to Sd06 must be changed and these can be accessed at user level (password 1) according to
the settings indicated in the following sections. Please see the relevant section for the methods of
accessing the parameters.
Summer compensation
In cooling mode, it is possible to increase/decrease the value of the working set point (parameter
St01 ) by a value proportional to parameter Sd01 . If parameter Sd01 assumes positive values, there
will be an increase, and if it assumes negative values, there will be a decrease.
The proportion of increase/decrease according to the outside air temperature value is controlled by a
compensation start set point (parameter Sd03 ), and by the relevant differential (parameter Sd05 ) that
can assume positive or negative values.
The compensated value of the set point cannot exceed the limits of the working set point in chiller
mode; it can therefore assume a value no lower than St02 and no higher than St03 .
When parameter Sd01=0 is set, the function is deactivated.
