condensation  may form on the surface
of the unit.
Heating mode is only available when the unit is connected 
to a system that can provide heating.
To  ensure  the  desired  temperature  is  achieved 
efficiently, ensure that:
The unit performs stably in the temperature range given in 
Table 3-1. If the indoor temperature is outside the unit's 
normal operating range, it may stop running and display an 
error code.
- All windows and door are closed.
- The airflow direction is adjusted to work in running mode.
