6.25.3 Error message functions
These functions can be used to maintain the required flow temperature. If the flow
temperature deviates constantly from the required level for more than the set period of
time, an error message is delivered. If, during an active alarm, the setpoint is
maintained again, the error message is canceled. If, during a DHW charging cycle and
within a parameterized time, the DHW storage tank cannot be charged to at least the
level of the switching differential, an alarm can be set off.
