Controls of the heat source
This control strategy is used when the heating system is
controlled using a building management system with a 0–10 V
controller output (
Fig. 22 at the end of the document).
Table 2
Control based on output/flow temperature
2.2.1 Output control
Linear relationship between the 0–10 V signal (U in volts) and
the required performance (P in percent)
Fig. 1
Linear relationship between the 0–10 V signal (U in
volts) and the required performance P (in percent
with reference to the maximum system
performance)
The connected heat source is switched on and off according to
the required output.
2.2.2 Flow temperature control
Linear relationship between the 0–10 V signal (U in volts) and
the required flow temperature
in °C with reference to the
minimum flow temperature range to the maximum flow
temperature range [default setting 20 to 90 °C]):

Linear relationship between the 0–10 V signal (U in
volts) and the required flow temperature
in °C)
The connected heat source is switched on and off according to
the required flow temperature.
