 The temperature setting value on the remote controller
should be higher than the indoor temperature; the
compressor has a delay start for three minutes;
 More time would be needed for starting heating under
extremely cold condition.
Poor cooling capacity
 Ensure the filter is clean;
 Turn on the fan to high speed to obtain the maximum
capacity;
 Make sure all the doors and windows, as well as the
sunroof are closed;
 Curtains and awnings can be used to decrease the
heating load.
