operation
Operation Modular
14.
Proceed as follows to calibrate the corresponding flow rate
metre:
In normal operation operate the device at 40 °C for at least 10
minutes.
Only in the case of water devices:
If present set the parameter
Pressure relief with unit OFF
at
Setting / Miscellaneous
to "OFF".
Switch the unit off using button
and wait at least 10
seconds.
Select the module affected e.g. "A1" with the
or
buttons.
Set parameter
Flow rate calibration
at
Service / Calibration /
Flow rate
to "ON".
The flow rate is calibrated automatically.
Only in the case of water devices:
If present set the parameter
Pressure relief at unit
OFF
at
Setting / Miscellaneous
to "ON".
Switch the unit on with the
key.

Inspection of calibration of Flow rate meter
In normal operation operate the unit at 40 °C for at least 5
minutes following calibration.
Close the corresponding shut-off valve between main and
return lines.
Flow rate returns to 0 L/min.
If this is not the case repeat the Flow rate meter point.
Repeat the Flow rate meter calibration item for each measuring
circuit.
