Val_lim_max_H: theoretical value of the high limit output in heating mode
Tlim: temperature of the supply sensor
128
: setpoint of high limit
129
: proportional limit band
When active, if the supply temperature goes above the maximum supply setpoint
128
, the heating valve is controlled consider
-
ing the lowest value between the theoretical output of the heating control and the theoretical value of the Val_lim_max_H limit.

Val_lim_max_H: theoretical value of the high limit output in heating mode
Tlim: temperature of the supply sensor
128
: setpoint of high limit
129
: proportional limit band
When active, if the supply temperature goes above the maximum supply setpoint
128 +
(proportional band
129
), the on/off
output in heating mode is controlled considering the lowest value between the theoretical on/off output of the heating control
and the theoretical value of the Val_lim_min_H limit.
