Set weather-dependent heating:
Note: There are 2 methods to set the weather
dependent curve. See "2-points curve"[4125]
and "Slope-offset curve"[4126]. Both curve
types require 4 field settings to be configured
according to the figure below.

▪ [0-03]: Low outdoor ambient temperature. –
40°C~+5°C
▪ [0-02]: High outdoor ambient temperature.
10°C~25°C
▪ [0-01]: Desired leaving water temperature
when the outdoor temperature equals or drops
below the low ambient temperature.
[9‑05]°C~[9‑06]°C
Note: This value should be higher than [0‑00]
as for low outdoor temperatures warmer water
is required.
▪ [0-00]: Desired leaving water temperature
when the outdoor temperature equals or rises
above the high ambient temperature.
[9‑05]~min(45, [9‑06])°C
Note: This value should be lower than [0‑01] as
for high outdoor temperatures less warm water
is required.
