Nominal value (multiple-boiler control unit)
In most cases this value corresponds to the set room temperature in normal mode.
With radiator systems, this value generally corresponds to the low end temperature.
A higher setting is recommended for convector heating systems.
Design temperature according to the geographical area.
Max. required supply temperature in accordance with the size of the heating surfaces.
The deflection factor of the heating curve must be adjusted according to the heating
surfaces used.
In the factory default setting, this value is set to 1.33 (radiator heating system).
Standard values for the deflection/curvature factor:
H Radiator heating system: 1.25 to 1.35
H Convector heating system: 1.40
H Underfloor heating system: 1.1
Minimum supply temperature.
Maximum supply temperature.
Supply temperature for external heat demand
If the ”external heat demand” contact is closed, the supply temperature will be raised to the nominal value.
Nominal value (multiple-boiler control unit)
Required supply temperature with closed contact.
In the ” Operating data” menu you can scan whether the control unit is set to “flowtemp set point”.
