High efficiency pump without control signal
When this type of pump is used, the speed is not controllable! The use of a line regulating valve (e.g.: Setter
balancing valve) is recommended!
r Connect the power supply for the high efficiency pump to output “Pump 1” or “Pump 2” and use the relay
output for phase (L)
r In the relevant menu, set the pump to “HE pump without control signal”
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%).
r Connect the power supply for the pump to output “Pump 1” or “Pump 2” and use the triac output for phase
(L)
r In the relevant menu, set the pump to “Pump without control signal”
