Max. number of starts/hour
Description
This function limits the number of pump starts and stops per hour
for the complete system. It reduces noise emission and improves
the comfort of booster sets with mains-operated pumps.
Each time a pump starts or stops, the controller calculates when
the next pump is allowed to start/stop in order not to exceed the
permissible number of starts per hour.
The function always allows pumps to be started to meet the
requirement, but pump stops will be delayed, if needed, in order
not to exceed the permissible number of starts/stops per hour.
The time between pump starts must be between the minimum
time between start/stop, see display
, and 3600/n, n being
the set number of starts per hour.
Setting range
1 to 253 starts per hour.

Standby pumps
Description
This function makes it possible to limit the maximum performance
of the Hydro MPC, by selecting one or more pumps as standby
pumps.
If a three-pump system has one standby pump, maximum two
pumps are allowed to be in operation at a time.
If one of the two pumps in operation has a fault and is switched
off, the standby pump will be started. The performance of the
booster set is thus not reduced.
The status as standby pump alternates between all pumps.
Setting range
The number of possible standby pumps in a Hydro MPC booster
set is equal to the total number of pumps in the system minus 1.
