PUMPS ALTERNATION DURING CONTINUOUS OPERATION
AUTOMATIC RESTART AND ANTI-JAMMING FUNCTION
VARIABLE MASTER
If for any reason one or more pumps are working continuously, in order to guarantee uniform wear of the pumps, every sixty minutes of
continuous operation of a pump, a forced exchange will be made with another pump on stand-by.
The changeover respects the alternating sequence of all the devices.
In case of stopping due to a water shortage, the devices will automatically make 10 double attempts to rearm over the 24 hours
following the failure, each lasting approximately 5 seconds to allow the pumps and the system to reload if possible.
The user can try to rearm the devices at any time by pressing the Restart button.
If for any reason the pumps remain idle for 24 consecutive hours, the devices will carry out a start-up of the pump motor for about 5
seconds without affecting the normal operation of the pressure set.
In case of a temporary blackout, the pressure set will automatically rearm once the electricity returns.
In case of malfunctioning of the Master device, the system will transfer the operation to the Slave device immediately followingfrom
the Master. If the original Master device is reset, it will automatically be reintegrated into the system as a Slave device.
INSTALLATION AND SETUP
OPERATION
Connect the devices together using the serial port.
Program the Presscontrol Wall PRO selected as Master following the instructions on the display.
Enable communication on the Master Presscontrol Wall PRO that automatically will transfer the data to the other connected
Presscontrol Wall PRO units that will act as Slave devices.
You can now start the pressure set.
To change the system pressure value and restart pressure value, only act on the Master device even if the pump is running.
The system pressure value and restart pressure value set on the Master device will be automatically transferred to the Slave
devices.
The Master device controls the Slave devices and determines the group operation.
Initially, the pump on which the Master device is installed starts up first, but if the water demand is such that this pump is not
able to maintain the set system pressure value, the second pump on which the Slave device is installed automatically starts.
Each time the pumps stop, the second and/or third, fourth pump start depending on how many pumps are installed, to return to
the Master device and so on. The alternation of the startup and operation of the pumps that make up the pressure set ensures
uniform wear of the pumps, which results in a longer life of the unit.
PRESSURE SETS
Presscontrol Wall PRO is equipped with a communication interface that allows up to 4 devices to communicate
simultaneously.
