Further settings
Pumps switched off through remote operation, bus command, control input External
OFF or 0 – 10 V signal run for a short time at least every 24 hours. This prevents block-
age after long downtimes.
In the "Settings" menu, select
1. "Device settings"
2. "Pump kick"
▪ to set the time interval for the pump kick between 1 and 24 hours (factory setting:
24 h).
▪ to switch the pump kick on and off.
NOTICE
When it is planned to switch off the mains voltage for a longer period of time, the
pump kick must be performed using an external control by switching on the mains
voltage briefly.
For this purpose, the pump must be switched on by the controller before the power
supply is interrupted.
The heating or cooling quantity is recorded by the pump's volume flow detection and
checking the temperature in the feed and return.
A temperature sensor in the pump housing records either the feed or the return tem-
perature, depending on its installation position.
A second temperature sensor must be connected to the pump using analogue inputs
AI1 or AI2.
The heating and cooling quantity is identified separately based on the application.
Activating heating/cooling quantity measurement
In the "Diagnostics and measured values" menu, select
1. "Heat/cooling quantity measuring"
2. "Heat/cooling quantity On/Off".
Then configure the sensor source and sensor position in the "Sensor feed temperature"
and "Sensor return temperature" menu items.
Configuring the sensor source in the feed
In the "Diagnostics and measured values" menu, select
1. "Heat/cooling quantity measuring"
2. "Feed temperature sensor"
3. "Select sensor source".
Configuring the sensor source in the return
In the "Diagnostics and measured values" menu, select
1. "Heat/cooling quantity measuring"
2. "Sensor return temperature"
3. "Select sensor source".
Potential sensor source options:
▪ Internal sensor
▪ Analogue input (AI1)
▪ Analogue input (AI2)
