Weather Curves (Kreg); Fixed Point Offset (Sp); Weather Compensation With Ambient Influence (Korr) - Ferroli CRONO REM Manual De Usuario

12.1 Weather curves (KREG)

The Remote Control calculates the flow temperature according to the weather curve set in the "KREG" parameter of
the PARAM menu at INST level.
The table below shows the "KREG" parameter range of variability.
Parameter
KREG
As the value set in "KREG" increases, the slope of the weather curve increases, consequently the flow temperature
increases (see "fig. 4 - Graph" on page 87).
The function has the attenuated outside temperature as its input parameter (x-axis).

12.2 Fixed point offset (sP)

It represents a temperature, which is added to the flow temperature, creating a "fixed point adjustment". This
parameter varies as shown in the following table with a resolution of 1°C.
Parameter
SP

12.3 Weather compensation with ambient influence (KORR)

Weather compensation with ambient influence is used to correct the value calculated by the weather curve considering
the difference in temperature between the ambient setpoint (SP
