If X1 and X2 are connected like in the figure, then, depending on setting 18(28)‑9, a
signal is output when the unit is ON and/or when it is in 24-hour ventilation.
If X3 and X4 are also connected to BRP4A50A, then, depending on setting 18(28)‑9,
a second signal can be output about fan operation or when the unit is in error. If a
heater is connected, the signal is output to the heater.
