[ VII Control ]
Priority order of the water-temperature-setting-input-signal sources
Water temperature can be controlled by using the signals from the four types of input sources (Heating, Heating ECO, Cooling,
Analog heating). The setting for the item with higher priority will override the settings for the items with lower priorities. The
water temperature will be controlled according to the temperature setting in the "Target water temperature" column that cor-
responds to a specific combination of the settings for the four items.

*1 If SW2-5 is set to OFF, water temperature will be controlled by the built-in thermistor TH3 on the unit.
*2 This mode is disabled in EAHV-P900YA-H.
*3 EAHV-P900YA can also set Cooling.
*4 AE-200 and BMS cannot both be simultaneously connected. Only connect one or the other.
*5 The ON/OFF contact setting can only be changed when the power is turned on.
No-voltage contact input K04-K05 OFF: Cooling (EAHV-P900YA, EACV-P900YA)
* When the operation mode is Cooling, K07-K08 (Anti freeze) and K13-K15 (Mode change) are disabled.
