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.
Setting range
0...1
The selected signal logic will automatically be displayed on this operating line.
0
Standard
The signal will not be inverted.
1
Inverted
The signal will be inverted before it is delivered.
4.270 Displaying voltage output Ux
Display of the actual value at voltage output Ux in %.
Display
0...100
DC 0 – 10 V ≙ 0 – 100 %
4.271 Output test voltage output Ux
• The voltage output signal can be checked
For test purposes, a predefined and constant signal can be delivered via output Ux.
Setting range
--- / 0...100
The settings have the following effect:
---
The functional test is not activated
0...100
The selected value [%] is fed to output Ux
as a fixed output signal. The pump defined on operating line 890 is oper-
ated at the relevant speed, or the heat demand delivered is correspond-
ingly high The relay pertaining to the pump will also be energized.
When leaving the operating line, the output test will be deactivated.
