Installation and operating instructions Wilo-Stratos GIGA 19
Behavior after being switched on The pump operates with its factory settings in initial commissioning.
• The service menu deals with the setting and converting of individual
pumps; see chapter 8 “Operation” on page 29.
• To correct faults, also see chapter 11 “Faults, causes and remedies”
on page 57.
Switching frequency At high ambient temperatures (> 104°F/40°C), the thermal load on
the module can be reduced by lowering the switching frequency
(menu <4.1.2.0>).
NOTE:
Switchover/modification must only be carried out when pump is at
standstill (motor not running).
The switching frequency can be changed via the menu or the CAN
bus. Lower switching frequencies result in increased noise levels.
Variants If the menu <5.7.2.0> “Pressure value correction” is not available on
the display of a given pump, that pump is a variant in which the fol-
lowing functions are not available:
• Pressure value correction (menu <5.7.2.0>)
• Efficiency-optimized activation and deactivation in double pumps
• Flow rate trend display

Safety
CAUTION! Danger of personal damage!
Modifying the settings for the differential pressure sensor can
lead to malfunctions. The factory settings are configured for the
supplied WILO differential pressure sensor.
• Default value: input In = 0-10 volts,
pressure value correction = ON
• When using the supplied Wilo differential pressure sensor, these
settings must not be changed!
Modifications are only needed if another differential pressure
sensor is used.
DANGER! Danger of death!
Incorrect installation and incorrect electrical connection can pose
a risk of fatal injury.
• Have the electrical connections established by licensed electri-
cians only, in compliance with the applicable regulations.
• Accident prevention regulations must be observed!
