5.2 Calculating the demand values for maximum speed
The demand values are shown on a label on the C−DELCON’s
microprocessor
The demand values for the maximum UP and DOWN speeds can be
calculated from the following table:
Valve type Flow range, Q
[l/min.]
Flow ring Conversion
C−LRV 175
15–45
46–90
91–250
R45
R90

1V <=> 4.8l/min.
1V <=> 9.7l/min.
1V <=> 29.1l/min.
C−LRV 350 251–500 R500 1V <=> 52.2l/min.

Calculation example
Flow rate UP (Q) 120l/min.
Flow rate DOWN (Q) 150l/min.
Valve selection:
Valve type C−LRV 175
Flow range 91–250l/min. *
Flow ring R250
Conversion 1V <=> 29.1l/min. *
Conversion:
Flow rate UP:
120[l/min] / 29.1[l/min] = 4.12V Fast UP
Flow rate DOWN:
150[l/min] / 29.1[l/min] = 5.15V Fast DOWN
Settings in the C−DELCON
* These values are taken from the above table.
