• 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)

Operates when input method for quiet function is set as external contact
Note4)
- 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
