Which controller functions are available depends on the selected system code number (Anl).
5.1

Weather-compensated control

When weather-compensated control is used, the flow temperature is controlled according to the
outdoor temperature. The heating characteristic in the controller defines the flow temperature
set point as a function of the outdoor temperature (–> Fig. 5). The outdoor temperature required
for weather-compensated control can either be measured by an outdoor sensor or it can be re-
ceived over an 0 to 10 V input.
