When turning off the taps, the pump stops but restarts after a few seconds without there being
any leaks in the system
The Delta P value is too low and the pressure drop which occurs when the pump is stopped is sufficient to

The pump goes on and off continuously
There are leaks in the system. Check the various hydraulic connections. Via the display check any
possible pressure drop when the taps are turned off. Check for any possible presence of dirt in the Mito
check valve which would prevent it operating correctly and if necessary clean with a jet of compressed
air.
The device frequently signals a condition of dry operation
During periods of system inactivity the suction pipe of the pump may have emptied preventing the pump
from filling at the next start. The Pmax value could also be set too high.
Check the sealing of the foot valve, if present, and correct Pmax setting.
At low water flows the pump operates irregularly
The flow is too low for the device to detect which causes the pump to stop. Install a small expansion
vessel (1-2 litres) on Mito output to make the system more flexible and reduce the number of restarts.
Increase the value of Stop Delay.
The pump does not stop
The system has major leaks or the unit check valve has clogged due to dirt; try to move the check valve
manually and check that the spring can ensure closing.
The sensor that detects valve position is damaged; have the unit checked by the manufacturer.
The pump operates at maximum speed but with poor performance
The pump is damaged or blocked due to foreign bodies.
The pressure drops when high water flow is demanded by the system
This is a normal condition due to the fact that the device is not capable of forcing the pump beyond its
maximum performance; above a certain flow, the pressure is not compensated for because the pump is
already working at maximum speed. If this is the case, it is recommended that a higher performance
pump be installed.

Ensure that the system piping is designed to avoid air being trapped near the Mito.
