7.9.5 Fire alert
The fire alert connection is an NC contact. When the contact is open, all pumps are
switched off in succession after a configurable start delay. An alert (red LED) is
output. In this case, the dry running protection and/or remote ON/OFF functions, if
enabled, are ignored.
When the contact closes, the pump sets will stop depending on demand. The alert is
cleared.
7.9.6 Setting the ambient temperature monitoring device (optional)
If the configurable ambient temperature value is exceeded, a warning message is
output. The ambient temperature can be read on the display.
The ambient temperature monitoring device cannot be used in combination with
digital inputs for remote reset, setpoint changeover and functional check run.
