NOTICE
The motor speed is switched on using the manual button or
external switch contacts. The switch contacts and the assigned
speed are activated.
During operation the pump is started up to the fixed speed
directly, without ventilation time.
If external control is not necessary, the cable ends need to be
insulated.
NOTICE
For easy interaction with peripheral devices such as electric heat
exchangers or dosing systems, installing a flow monitor with the
appropriate evaluation unit is recommended. This can also output
a fault message.
