13. CONTROL
External input terminal
The piping length must be within 100 m.
External input terminal (refer to [Fig. 1-7-B]) is ineffective when the circuit is open.
Refer to [Table 2] through [Table 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. 3-1-F].
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

*2 Effective when SW 4-3 is set to ON.
*3 Effective when SW 4-4 is set to ON.
*4 PWFY-EP100VM-E1/E2-AU only
*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 enabling the
unit to maintain low water temperature to prevent water pipes from freezing.
*7 PWFY-P100VM-E-BU only
When setting Heating ECO or Anti-freeze mode, reset all power supply of all units (outdoor/indoor units).
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.
