5.4.6.2 Heating system
Access code: No access restriction
Factory setting: 1.30 (Radiator systems) for direct circuit
1.10 (Floor heating systems) for mixed circuits
Setting range: 1.00...10.00
Function:
This parameter refers to the type of heating system (floor, radiator, convector
heating) and can be compared to the exponent of the relevant heat exchanger. The
setting determines the curvature of the heating characteristic of the direct heating
circuit and compensates the performance losses at low temperatures by means of
its progressive characteristic.
Depending on the type of heating system the following settings are recommended:
1.10 Slightly progressive heating characteristic for floor or other panel heating
systems.
1.30 Progressive standard characteristic for all radiator heating systems with m-
values comprised between 1.25 and 1.35.
2.00 Progressive heating characteristic for convector and baseboard heating
systems
>3.00 Very progressive heating characteristic curves for general ventilator
application with high start temperatures.
