Attention: If DIP SWITCH configuration is used, the differential restarting pressure is calculated as SP * DP. If the set
point is 4 bar and DP is 50%, the restarting pressure RP is 2 bar.
The names pump P1 and P2 are only indicative. If exchange mode is activated, the pumps P1 and P2 are alternated as
specified in the exchange mode.
The two pumps will always be started alternately with a minimum interval of 2 seconds from each other.
Example
of Regulation with Standard expansion vessel and Regulation with additional expansion vessel:
SP= 4 bar
RP = 2 bar Attention: if DP is set (with the trimmers) RP=SP*DP
Pressure boosting operation standard vessel < 100 litres
P1 System pressure <= SP
P2 System pressure <= SP – RP
Table 12: Pressure boosting operation standard vessel < 100 litres
Operation with additional expansion vessel > 100 litres
P1 System pressure <= SP
P2 System pressure <= SP – 2%
