8.5.5 Outdoor Unit current control when heating
Note:
The frequency in the table
goes down in accordance
with the present frequency,
determine every 2 seconds
whether it keeps going
down or it is recovering.
8.5.6 Indoor evaporator protection against high temperature
When the temperature of indoor heat exchanger is higher than 53°c, the frequency will reduce one
step and last for 20 seconds every time until the temperature drops down lower than 53°c. If the
temperature drops down < 48°c, the limitation then will be removed (the frequency will not going
down further when reaching 35Hz).
When the temperature of indoor heat exchanger is higher than 63°c, shut off the compressor.
8.5.7 Indoor fan vanes at heating mode will swing in accordance with the following:
When just plugged in for heating, the vanes will open to the standard angle 220°.
The vane angle can be set by remote control at any angle between 0° and 220° (every setting can
adjust 6°) or set swinging (swinging angle will be 25°).
8.5.8 Defrosting operation
8.5.8.1 Defrosting precondition:
Defrosting starts when meeting one of the three conditions:
①
The temperature of outdoor heat exchanger remains consecutively lower than 3°c for more than
40 minutes, and the temperature remains consecutively Ti1 for more than 3 minutes.
Model Ti1:
MSG-09HRI : -4°c
MSG-12HRI : -6°c
MSG-09HRIN2 : -9°c
MSG-09HRIN2 : -9°c
