– 25 – Output signal function wiringConnect the following output signals from the hot water module.NOTEAuxiliary relays (locally procured) must be connected to output signal function wirings to allow connection to thehot water module output signal functions. The maximum current output signal, from each of the output signalfunction wirings, is 16 mA. Please ensure the rated current of the relay coil is less than 16 mA to avoid damage tothe hot water module P.C. board.▼ Output function wireCAUTIONOutput signal functions are separated from primary basic insulation.• To prevent noise trouble, use 2-core shield wire.• Determine the wire length between the hot water module output signal function terminal block and the relay upto 2 m.• Locally procure and install protective devices such as the heater and pump.Terminalblock No. Function CommentsCOM DC12V (COM) Common for connector S2 ~ S5S1 Defrosting output (COM-S1) DC12VRelay coil is less than 16mA.S2 Line heater output (COM-S2) DC12VRelay coil is less than 16mA.S3 - -S4 Heating thermostat ON output (COM-S4) DC12VRelay coil is less than 16mA.S5 Pump output (COM-S5) DC12VRelay coil is less than 16mA.COMS1S2S3S4S5ExternalactuatorOutput function wireHot water moduleoutput signalfunction terminalblock (CN60)Locally procuredRelay Outside trouble input wiring• In case of connecting the Relay (procured locally) for outside trouble input, connect a connector with wire(accessory) to CN703 on I/F P.C.
