7.13 Requesting demand over a 0 to 10 V signal
The controller can request an analog request for an externally required signal assigned “0 to
10 V corresponds with 0 to 120 °C flow temperature“. For this purpose, the output Y1 is
used as an alternative to issue the control signal. Several requests can be processed simulta-
neously over the device bus.
Note!
If, for example, four supplementary heating circuits pass on their demand as a 0 to 10 V sig-
nal split between two controllers connected over a device bus, two systems should not be
configured both with system code number Anl 10.0. Otherwise, the heating circuit RK1 of
system Anl 10.0 in the controller processing the request would process the request of the sec-
ond controller.
In this case, configure system Anl 5.0 (TROVIS 5579 only) in the controller processing the re-
quest.

7.14 Connecting potentiometers for valve position input
The FG1 and FG2 inputs can be used to connect potentiometers, for example, to input valve
positions when a resistance room sensor is not configured in the control circuit concerned.
The use of TROVIS 5570 Room Panel is possible.
