* 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.
HWE1517A
ON (Close)
Run/Stop The unit will go into operation when the water
temperature drops below the preset temperature.
Forced/ The fan will remain in operation after the compressor
Normal has stopped (including when the OPERATION status
is "STOP").
On/Off The unit will operate at or below the maximum
capacity level that was set for the Peak-demand
control setting.
On/Off Heating operation with the set outlet hot water tem-
perature
On/Off Heating operation with the maximum water flow
amount
On/Off Operation using the set capacity as an upper limit
Action
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.
Conditions in which the contact closes
(turns on)
Close/Open The unit has made an abnormal stop.
Close/Open The "Unit Operation" contact (item (a) above) or
the ON/OFF button on the remote controller is ON.
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).
Close/Open During freeze-up protection operation
During pump residue operation
PAR-W31MAA
AE-200
OFF (Open)
The unit will stop except when the unit is in
the Anti-Freeze mode.
The fan will stop when the compressor
stops.
