Installation and operating instructions Wilo-Stratos GIGA 15
The emergency operation speed can be set in menu <5.6.2.0> (see
chapter 6.3.3 on page 17).
• The master's display will show the status of the double pump. On the
slave display, 'SL' will appear.
• The master pump is the left pump in the direction of flow.
Connect the differential pressure sensor to this pump.
The measuring points of the differential pressure sensor of the master
pump must be on the suction and pressure side of the double-pump
system in the corresponding collector pipe (Fig. 18).
InterFace module (IF-Module) For communication between pumps and the building management
system, one IF-Module (accessories) is required per pump. This is
plugged into the terminal space (Fig. 1).
• The master-slave communication uses an internal interface (terminal:
MP, Fig. 26).
• Normally for double pumps, only the master pump must be equipped
with an IF-Module.
NOTE:
The procedure and further information for commissioning and confi-
guring the IF-Module on the pump can be found in the installation and
operating instructions of the IF-Module used.
