current flow. The pressure is equal to the set

pressure (Hset on the drawing) at maximum

power; at 0 flow it is equal to HQ%(default 50%,

HQ% can be set on the pump webpage) of the

set pressure. In between, the pressure changes

linearly, relative to the flow.

In regulated mode we can only set the pump pressure (Hset on the drawing).

We can only scroll through the other parameters.

5.2.1 Twin pump operation
During normal operation, only one pump is active, while the other is in

standby. Pumps change duty once per day. Every pump operates according

to its own settings, so parameter changes should be made on both pumps. If

any pump detects an error or loss of communication, the standby pump will

start in less than 15 seconds.
