4.5.3 Connection of outputs R1 and R2
Output R1:
Semiconductor relays (TRIAC), also suitable for RPM control; max.
switching current: see type plate
CAUTION
Avoiding damage and malfunctions
When connecting an external relay or contactor, or when connect-
ing a pump which has its own electronic RPM control, the controller
output's RPM control must be deactivated (see chapter 7.4.3 "Setting
the RPM control parameter").
