Installation and operating instructions Wilo-Control EC-Fire 41
4 Application (intended use)
The EC-Fire switchgear is used for the pressure-
dependent and volume-flow dependent control
of up to 3 constant speed pumps in fire extin-
guishing systems. Signal detection occurs by
means of pressure switch, pressure sensor, flow
switch or volume flow sensor.
Intended use also means compliance with this
manual. Any other use is regarded as
non-compliant with the intended use.
