6 Functions of the heating circuit
Which controller functions are available depends on the selected system code number (Anl).
6.1 Weather-compensated control
When weather-compensated control is used, the ow temperature is controlled based on the
outdoor temperature. The heating characteristic in the controller denes the ow temperature
set point as a function of the outdoor temperature (seeFig. 3). The outdoor temperature re-
quired for weather-compensated control can either be measured at an outdoor sensor or re-
ceived over the 0 to 10V input.
