7-3-8. Error / Operation output
Operation
In-operation output: An in-operation indication signal is output as long as at least one indoor unit is in operation in
the line.
Failure output: A failure in dication signal is output if check code occurs in at least one indoor / outdoor unit in the line.
Note 1: Output Relay (K1, K2) Contact Specifications
Output terminals (OUTPUT1, 2) must satisfy the following electrical rating.
When connecting a conductive load (e.g. relay coil) to loads K1 and K2 insert a surge killer CR (for an AC power
supply) or a diode for preventing back electromotive force (for a DC power supply) on the bypass circuit.
<Electrical Rating>
220-240 VAC, 10 mA or more, 1 A or less
24 VDC, 10 mA or more, 1 A or less (non-conductive load)
