External input terminal
The piping length must be within 100 m.
External input terminal (refer to Fig. V. 1.(7).4) is ineffective when the circuit is open.
Refer to Table V. 1.(7).2 through Table V. 1.(7).4 for information about each contact.
Only the "pump interlock" function is ineffective when the circuit is short-circuited.
Connect a relay circuit to the external output terminal as shown in Fig. IV. 3.(10).2.
The specifications of the relay circuit to be connected must meet the following conditions.
Contact rating voltage >= DC15V
Contact rating current >= 0.1A
Minimum applicable load =< 1mA at DC

*5 When Heating ECO mode is effective, the outlet water temp. will be changed
based on ambient temp. automatically. (Only Y/HP (ZUBADAN)/R2-series)
*6 When Anti-freeze mode is effective, the unit will set the heating temperature range
between 10ºC~45ºC enablng the unt to mantan low water temperature to prevent
water pipes from freezing.
*7 PWFY-P100VM-E-BU only
Note: When setting Heating ECO or Anti-freeze mode, reset all power supply of all units (outdoor/indoor units).
Note: Dip S/W 1-1 OFF: Water Inlet Temp.
Dip S/W 1-1 ON : Water Outlet Temp.
The factory setting for Dip SW 1-1 is OFF.
