5. Use and programming 

 
The pump can be operated in a basic way through the included keyboard. 
 

 

 

Stand-by red led 

Red led ON: unit is powered with correct input 
voltage 
Blinking red led: undervoltage 

 

Motor running 
green led 

Green led ON: motor is running 
Green led OFF: motor is stopped 
 
When the units is on “constant value” control mode, 
the green led blinks with higher frequency as much 
as the measured value is next to set value. If 
measured value is the same as set value, the green 
led is steady. 

 

Alarm yellow led 

Yellow led blinks with frequency which depends on 
alarm type. See “Alarms” chapter. 

 

Motor start and 
stop button 

Motor start and stop. 
 
If the unit is in alarm status, it is possible to try 
resetting the alarm by pressing the button two 
times. 

 

SET green led 

Green led is ON when it’s possible to modify the set 
value (constant value mode) or the set frequency (fix 
frequency mode). Keep pressed the Up button or the 
Down button more than 5 seconds in order to 
enable the set adjusting. 
 
If the SET led is off, it is not possible to change the 
set value. 
 
When two or more units are in COMBO mode, the 
SET led blinks only on master unit. In this way it is 
possible to understand which unit in the group is the 
master and thus act on it to start and stop the 
system. 
 
Green led blinks fast when the unit is connected to 
smartphone and remotely controlled by the App. 

 

Up button 

Through the UP button is possible to increase the set 
value (constant value mode) or the set frequency (fix 
frequency mode). 
In order to allow set changing it is necessary to keep 
pressed the UP button or the DOWN button more 
than 5 seconds till the green SET led becomes ON. 

 

Down button 

Through the DOWN button is possible to reduce the 
set value (constant value mode) or the set frequency 
(fix frequency mode. 
In order to allow set changing it is necessary to keep 
pressed the UP button or the DOWN button more 
than 5 seconds till the green SET led becomes ON.
