Note: The warning relay differs from the alarm relay as it is only activated for warnings, that is, signals only, which
have no direct effect on the operation of the unit, and the display does not show the alarm symbol (bell).
Compressor
N.B. The alarm relating to the circuit with the fault must not interact with the operation of the other
circuit, as long as the condenser is not shared in common.
