Adjust the parameters referring to differential pressure 
(signal 2) if a DPS is used:

 

Min Alarm:

If the minimum differential pressure is reached, the 
relay is energised, 

 appears in the display, the LED 

flashes green and an alarm message appears in the 
submenu “Reports”. 

 

Î

Select “Yes” or “No” to activate or deactivate the 
function.

If this function is selected, the minimum value for the 
alarm has to be adjusted. 
Adjustment range: 0 ... 99.9 bar

Adjustment range: 0 ... 99.9 bar

Heat quantity measurement

Heat quantity measurement is carried out by means of the 
difference between the flow and the return temperature as 
well as the measured flow rate. If the function is activated 
(factory setting), make the following adjustments:
