by the outdoor unit for 3 minutes.
• When power is not being supplied to the water heat exchanger unit.
• When the outdoor unit address set for the water heat exchanger unit and the outdoor unit do not match up.
• When an error occurs with the indoor/outdoor operation wiring (short-circuit, severed wires, ground.)
• When electrical voltage is applied to the indoor/outdoor operation wiring.
• When affected by noise.
• When the water heat exchanger unit's control board or peripheral equipment is defective.
