The voltage-modulated output can be used either for speed-controlled pumps or as an
output for a voltage-proportional temperature request.
Speed-controlled pumps:
The output signal at UX corresponds to the required speed for the selected pump.
Boiler temp setpoint:
The output signal at UX corresponds to the boiler setpoint
Output demand:
The output signal at UX is proportional to the output demand via the primary circuit
flow.
Heat request:
The output signal at UX corresponds to the primary circuit flow setpoint.
The voltage signal can be inverted. Thus, it can also be used to control pumps with
variable speeds, or temperature request receivers that use inverted signal logic.
This operating line is used to define the maximum temperature request
(corresponding to 10 V).
