OPERATION
ZP Speedcontrol Comfort is a compact automatic control device ( see fig.2) designed for the single and three-phase pump´s
automation, with an electronic system managed by a software responding to the rigorous requirements of efficiency and
safety of the most important builders of pumps. It includes a frequency inverter that regulates the speed of the pump in
order to keep constant the pressure independently of the flow given.
The system incorporates a LCD screen where the parameters configuration is very easy and intuitive. Once the configuration
parameters are introduced, the ZP Speedcontrol Comfort manages the start-up of the pump and the frequency inverter. It
assures a constant pressure and an important costs reduction because at any time the control will feed the system with the
right and necessary output, obtaining a maximum energetic efficiency. In order to establish the ideal pressure in the
installation is suitable to consider following criteria:
Hm: Max. water column height in m. It depends on the number of floors and it corresponds to the height from the pump to the last
floor. Every 10 m of height corresponds approximately to 1 bar (0.98) bar.
Pw: Available minimum pressure in last floor (usually 1.5 bar).
Pc: Pressure drop. It can be considered with a simplified criteria as 0.033 bar/m.
Prmin: Minimum resultant pressure. It is the sum of the previous pressures and it will be the operating pressure of the pump.
Example for a 5 floors building (15 m) with pump placed at level 0:
Hm =15 m
?
1.5 bar Pw = 1,5 bar Pc=15 x 0,033 bar
?
0,5 bar Prmin = 1,5 + 1,5 + 0,5 = 3,5 bar

function (Automatic Reset Test). If the device has been stopped due to the action of the safety system against
over-intensities, the
ART
tries to connect the pump, with a programmed periodicity because the water supply could
have been restored
Automatic restore system after an interruption of power supply. System is activated in AUTOMATIC mode keeping the
configurationparameters (see “CONFIGURATION” chapter).

Control panel (Fig.1):
LCD screen, for alarm menu with permanent pressure indication.
START/STOP push-button to act by hand each one of the pumps
ENTER pushbutton to save data in memory.
ON/OFF pushbutton to change rom AUTOMATIC to MANUAL mode or vice versa.
MENU push-button
Keyboard for the access to programming menu.
Digital gauge.
Connections for detection of minimum water level in aspiration tank. This system is independent of the safety against
dry operation. Is optional.
AIS
function (Anti-Ice System). If temperatures under 5 ºC are detected it will start periodically the pump avoiding the
freezing of the water inside the pump.
For environment temperatures under 0ºC it is very important to take measures to avoid water freezing.
Register of operational controls: infomation about operating hours, counter of starts, counter of connections to the power
supply.
Register of alarms: information about type and number of alarms since the starting up of the device.
Mode MASTER & SLAVE. Communication with another device ZP Speedcontrol Comfort to work in group. Optional.

MASTER AND SLAVE OPERATION
The group MASTER-SLAVE is constituted by a device configured as ZP Speedcontrol Comfort MASTER - responsible of the
group´s control - and a ZP Speedcontrol Comfort configured as SLAVE controlled by the master device.
Due to the alternating sequence of operation, the ZP Speedcontrol Comfort configured as MASTER began the first cycle as
MAIN device -its pump is the first to start - but in the next cycle it becomes SECONDARY - its pump is the second to start -
and so on. Therefore, the fact that a device is configured as MASTER involves control of the group but this fact does not avoid
its work alternately as SECONDARY device.
CLASSIFICATION AND TYPE
