Terminal DO7 / DO7: Thermostat on Digital output (DC12 V)
• When the thermostat of Dx-coil is ON, a signal comes out.
Terminal DO8 / DO8: Cooling / heating start up control signal output
• Outputs the start control signal for cooling and heating operation.
Terminal DO9 / DO9: Pre defrost signal
• Output just before defrosting (at least 5 minutes before).
Terminal DOA / DOA: Cool open heat close output
• Heating mode is close, Cooling mode is open.
Terminal DOB / DOB: Notice code output
• Issued when Notice code is output. For details, see the outdoor unit Service Manual.
Terminal DOC / DOC, DOD / DOD, DOE / DOE: FAN speed output
• If select the fan output from interface, use this output. For TA and TF types, the output changes by changing the fan
speed from th
e remote controller.
DOC = High / DOD = Mid. / DOE = Low
Terminal N1 / N1, N2 / N2: Nothing
The specifications of Terminal DI1 to DI5 are as follows.
• You can switch between voltage and non-voltage with SW701.
