4-5. Defrost Operation (During Heating)
4-5-1. Defrost Detection (detected at the outdoor unit)
A : Distribution of outdoor heat exchanger temperature down ≤ detection by Ta : Ta = 0.5˚C
B : Temperature of outdoor heat exchanger ≤ detection by Tb : Tb = -3˚C
C : Accumulated time of COMPor operation ≥ detection by Tc : Tc = 60 minutes
D : Continuous operation time of COMPor ≥ detection by Td : Td = 30 minutes
E : Distribution of outdoor heat exchanger temperature down ≤ detection by Te : Te = 1˚C/2˚C(Outdoor unit option, refer to Table 5-1 )
F : Temperature of outdoor heat exchanger ≤ detection by Tf : Tf = -6˚C
G : Accumulated time of COMPor operation ≥ detection by Tg : Tg = 60/70/80/90/100 minutes(outdoor unit option, refer to Table 5-1 )
Defrost operation is done by the signal of defrost detection from the outdoor unit.
Defrost detection = (A B C) (D E F) (B G)
4-5-2. Release of defrost
A: Outdoor pipe temperature during defrost operation ≥ 15˚C/20˚C/25˚C(outdoor unit option, refer to Table 5-1)
B: Max time of defrost operation is 9 minutes 30 seconds
Defrost is released by the defrost release signal from the outdoor unit. Defrost release = A B
4-5-3. DISPLAY
ΠDefrost lamp is on additionally during the defrost cycle.
´ Only the defrost lamp is off when the defrost is released.
4-5-4. When operation off during defrost operation
ΠCOMPor OFF after completion of defrost operation
´ Defrost lamp is on during the defrost operation and the lamp is off after the release of defrost operation .
4-5-5. When the mode is changed to cooling operation during defrost operation
ΠAfter the completion of defrost, the cooling operation starts.
´ DISPLAY is changed from heating to cooling and the defrost lamp is on
