Short circuit - 2nd
mixed heating cycle
inlet temp.
S06
Short circuit - 2nd mixed heating cycle inlet temp.
ID7332 Anti-freeze protection
µ
PC
The anti-freeze protection in the heat pump's heat exchanger
was triggered due to an inlet temperature that is too low. After
eliminating the cause of the error, the controller must be
restarted to reset the error.
ID7333 Negative temp. differ-
ential
The temperature difference when the heat generator is active
is implausible
ID7334 Comm. signal
Communication between operating unit SMT 1 and power unit
SMT 1 I/O was interrupted.
