4.269 Voltage output signal logic Ux
•
Invertible voltage output signal
The voltage signal can be inverted. This makes it possible to also control pumps with
variable speeds, or receivers of the heat demand that use inverted signal logic. This
makes it possible to also control variable speed pumps or receivers of the heat demand
signal with inverted signal logic.
