Application macros 111
SPFC control macro
This macro provides parameter settings for pump and fan control (SPFC) applications
with a soft start function. To enable the macro, set the value of parameter
to 15 (
).
For the parameter default values, see section
Default values with different macros
on
page
. If you use other than the default connections presented below, see section
Note:
Parameter
must remain in the default setting 0 (
).
