Note:
When T1-Ts keep in the same temperature zone for 3 minutes, the compressor will run as the below
rules:
A~E: Increase the frequency to the higher level until to F10.
F: Keep the current frequency.
G: Decrease the frequency to the lower level until to F1.
H: Run at F1 for 1h.(if T1-Ts-ΔT >6 ℃, compressor will stop)
Meanwhile, the compressor running frequency is limited by the current.
TYPE I1HEAT I2HEAT I3HEAT
18K 5 6 7
24K 11 12 13
If the current increased more than I2HEAT, the frequency will decrease automatically, if the current
raise to over I3HEAT, the compressor will stop and restart 3min later.
During the frequency decreasing, if the current deceased to between I1HEAT and I2HEAT, the
frequency will hold. If the frequency not changed for 3min, the frequency will increase to a higher level,
and it can increase twice at most.
If the current deceased to lower than I1HEAT, the frequency limit will be invalid.
8.4.3.2 Outdoor fan running rules:
Outdoor fan and compressor start up at the same time, outdoor fan stop 30s delay after the
compressor stopped.
The outdoor fan have two speeds, it’s controlled by T4 as following rules:
