❒ Hydraulic module FRHYU21: Connect pump with relay and RC element isolated from the output
❒ Hydraulic module FRHYU22: Connect the power supply for the high efficiency pump to output "Pump 1" or
“Pump 2” and use the relay output for phase (L)

AC pump without control signal (pulse package control)
On older pumps without a control signal that are not highly efficient, the speed control is implemented via a
pulse package control. Please note that the minimum speed may need to be adjusted on some pumps (default
setting: 30%).
