This input network variable is used to switch the pump on and off and specify
a setpoint.
The network variable consists of a status byte in which the switch-on condition
is transmitted and a value byte in which the setpoint is transmitted.
If a status byte of 0 is set, the pump is switched off. If a status byte of 1 is set,
the switch-on condition depends on the value byte.
If a setpoint of 0% is preset, the pump is switched off. If a setpoint greater than
0% is preset, the pump is switched on if the status byte is 1. The setpoint can
be changed in steps of 0.5%.
If setpoints greater than the upper setpoint limit value are set, they are reduced
to the upper setpoint limit value. Accordingly setpoints below the lower
setpoint limit value are raised to the lower setpoint limit value.
The upper and lower setpoint limit values may change if the pump is operated with
an external sensor (see nviRemotePress, nciRemMinPress and nciRemMaxPress).
