Heating curve

9.6.1

Purpose

With space heating systems, flow temperature control is always weather-
compensated. The heating curve assigns the flow temperature setpoint to the pre-
vailing outside temperature.
9.6.2

Settings

The heating curve settings are made via 2 operating lines.
The following settings are required:
Flow temperature setpoint at an outside temperature of 5 °C
Flow temperature setpoint at an outside temperature of 15 °C
The basic settings during the commissioning phase are made based on the plan-
ning documentation or according to local practices.
They are made on operating lines 14 and 15.
Op. line Setpoint
14 Flow temperature setpoint at an outside temperature of 15 °C
15 Flow temperature setpoint at an outside temperature of -5 °C
