Usual input: Operate by current status of contact
Instant input: Operate when contact signal changes from OFF to ON / from ON to OFF
Note1)
Value of water outlet set temperature = 5.625 x Current - 32.5
Heat (Hot water) mode recognizes minimum 25 °C and maximum 55 °C
Cool (Cool storage) mode recognizes minimum 5 °C and maximum 25 °C (Minimum -10 °C when using low
temperature function)

Note3)
If operation pattern is not standard control, control standard temperautre depends on external water outlet
temperature sensor. External water outlet temperautre sensor should be installed where can represent the
temperature of water pipe system.

Note4)
Operates when input method for quiet function is set as external contact
- If the contact is short, quiet function operates in Cool/Heat mode.
- Quiet function by Module Control operates in Cool mode and night time.
Note5)
Operates when input method for demand function is set as external contact
Note6)
Operates when input method for forced fan function is set as external contact
Note7)
Operates when input method for water law function is set as external contact
