6-8-7. 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.
Error output: An error indication signal is output if an error occurs in at least one indoor/outdoor unit in the line.
Note 1: Output Relay (K1, K2, K3) Contact Specifications
• Output terminals (OUTPUT1, 2, 3) must satisfy the following electrical rating.
• When connecting a conductive load (e.g. relay coil) to loads K1, K2 and K3, 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.
The optional P.C. board should be connected to the header outdoor unit (U1).
