8.10 Heating Circuit Constant Temperature Control (..2.. or ..3..)
NOTE: This function must be activated in the HYDRAULIC menu for the corresponding
heating circuit (Direct heating circuit, Mixing circuit 1, Mixing circuit 2).
Function: The control circuit is operated at a constant flow temperature value. The demand
value is transmitted to the heat generator. The switching program of the
corresponding heating circuit is active.
The constant temperature setting is carried out with the relevant parameter
"Constant Temperature Setpoint".
If the function is activated at a mixer output, a flow sensor must be installed to adjust
the flow temperature.
If priority DHW charging is active, the heating circuit is switched off.
8.11 Fixed Value Control (..2.. or ..3..)
Function: As in the case of constant control, but the demand value is not transmitted to the heat
generator. Switching time program not active.
