Description
The function allows you to invert the control of mains-operated
pumps (MPC-S). That is, to set whether pumps are to be started
or stopped depending on the actual value.
A start/stop band must be set in order to use this function. See
fig. 50.
Normal
A pump is stopped when the value becomes higher than Hset +
start/stop band. And a pump is started when the value becomes
lower than Hset. See fig. 50.
Inverse
A pump is started when the value becomes higher than Hset +
start/stop band. And a pump is stopped when the value becomes
lower than Hset. See fig. 50.

higher priority than the setpoint ramp which will be
overruled.

set.
