maximum temperature. Make sure that the end user provides the calves with feed using an al-
ternative method as long as feed operation is interrupted.
You can correct the fault as follows:
1. Confirm Fault, temperature too high by choosing .
2. In Boiler water start?, press and keep depressed .
3. Release water from the heat exchanger’s boiler into the mixer beaker until the fault message
