When using a local controller, refer to the table below for the types of input/output signals that are available and the operations that correspond to the signals. External Input/Output Input type Dry contact ON (Close) OFF (Open) Terminal block/connector (a) UNIT OPERATION Run/Stop The unit will go into operation when the water temperature drops below the preset temperature. The unit will stop except when the unit is in the Anti-Freeze mode. TB6 23-24 (b) FAN MODE Forced/Normal The fan will remain in operation after the compressor has stopped (including when the OPERATION status is "STOP"). The fan will stop when the compressor stops. TB5 34-35 (c) PEAK-DEMAND CONTROL On/Off The unit will operate at or below the maximum capacity level that was set for the Peak-demand control setting. - TB6 19-20 (d) Hot water storage mode On/Off Heating operation with the set outlet hot water temperature Stop TB6 32-33 (e) Heating-up mode On/Off Heating operation with the maximum water flow amount Stop TB6 31-33 (f) Low-noise mode On/Off Operation using the set capacity as an upper limit Normal operation TB6 21-24 Analog Terminal block/connector Input type Action (g) WATER TEMP SETTING CONTROL Water temperature control can be set by using the external analog input to the CN421 on the circuit board. One analog input type can be selected from the following types: 4-20 mA, 1-5 V, 0- 10 V, or 2-10 V. CN421 2(+)-3(-) (h) EXTERNAL WATER SENSOR 1 (optional) - TB5 25-26 (i) EXTERNAL WATER SENSOR 2 (optional) - TB5 27-28 (j) EXTERNAL WATER SENSOR 3 - TB5 27-30 (k) EXTERNAL WATER SENSOR (secondary circuit) - TB5 T1-T2 (l) EXTERNAL PUMP (secondary circuit) - CN512 1-3 (m)FLOW SENSOR (secondary circuit) - TB4 13-14 (n) FLOW ADJUSTMENT DEVICE (secondary circuit) - TB6 10-12 Output type Contact type Conditions in which the contact closes (turns on) Conditions in which the contact opens (turns off) Terminal block/connector (o) ERROR INDICATOR Close/Open The unit has made an abnormal stop. During normal operation TB8 74-75 (p) OPERATION INDICATOR Close/Open The "Unit Operation" contact (item (a) above) or the ON/OFF button on the remote controller is ON. The "Unit Operation" contact (item (a) above) or the ON/OFF button on the remote controller is OFF. TB8 72-73 (q) EMERGENCY SIGNAL Close/Open Water temperature has dropped below the Booster Heater Operation Water Temperature (TWL1 value)(Item code 1057) and the outside temperature (TAL1 value)(Item code 1058). Water temperature is at or above "TWL1+2oC" or the outside temperature is at or above "TAL1+2oC". CN512 5-7 (r) EXTERNAL DEVICE Close/Open During freeze-up protection operation During pump residue operation Other than the items at left TB8 86-87 RC/ SC/ M-NET REMOTE CONTROLLER PAR-W31MAA TB5 RA-RB SYSTEM CONTROLLER AE-200 TB7 MA-MB * M-NET - TB3 MA-MB * When AE-200 is connected, leave the power jumper on the outdoor unit as it is (Connected to CN41 at factory shipment). If the power jumper is connected to CN40, power will excessively be supplied and AE-200 will not properly function. 58PDF Image | QAHV-N560YA-HPB
