[1] Functions and Factory Settings of the Dipswitches

1. 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 listed below.
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
corresponds to a specific combination of the settings for the four items.
No-voltage contact input K91-K93 ON: Heating (EAHV)
Priority 1 Priority 2

*1 This mode is disabled in EAHV.
*2 EAHV can also set Cooling.
*3 AE-200 and BMS cannot both be simultaneously connected. Only connect one or the other.
No-voltage contact input K91-K93 OFF: Cooling (EAHV, EACV)
* When the operation mode is Cooling, K40-K41 (Anti-freeze) and K40-K42 (Mode change) are disabled.
