Instead of setting the flow rate for the system using a flow rate
limiter, it is better to adjust the
flow rate
using the switch on the
pump and by means of the
“
max. speed
”
setting on the controller
(see 12.9.4). This saves electricity!
The
service values
(see 15.) include not only current measurement
values and operating states, but also all of the settings for the controller.
Write the service values down just once after commissioning has been
successfully completed.
In the event of uncertainty as to the control response or malfunctions the
service values are a proven and successful method for remote diagnosis.
Write the service values down (see 15.) at the time that the suspected
malfunction occurs. Send the
service value table
by fax or e-mail with
a brief description of the error to the specialist or manufacturer.
