The control outputs are deactivated at the factory. In the active state, they can be enabled by
an assigned output, i.e. by an output specified by the schematic and the program number.
If a control output (0 to 10V or PWM) is activated, then the analogue stage is displayed in the
basic menu after the measured values below “ANL 1“ or “ANL 2“.
The instructions on
page 9 should be observed for the speed control in pump valve
systems.
OP Setting the outputs to enable the control output.
In other words, the analogue output is only released if the output set here is
switched on. If no output is selected, then the analog output is always released.
(ex works = --).
Setting range: combination of all outputs (such as OP1, OP23, OP123)
OP -- = The analogue output is not assigned to any output;
rather, it runs independently.
The pump speed control can be used to change the delivered quantity – i.e. the volume
flow – via one of the control outputs. This provides constant levels of (differential)
temperatures in the system.
A simple solar diagram is used to illustrate the possibilities of this process:
