● Standard and All Fresh Process Modes
Two different process modes are selectable:
(1) Standard Process
Standard Process in Cooling Mode
In a situation where the outdoor ambient temperature is lower than 66
o
F (19
o
C), the compressor stops and
the indoor temperature is cooled down with an intake of outdoor fresh cold air controlled by the damper.
The minimum guaranteed fresh air intake can be set through the d7 setting (7% or more of the total outlet
air).
• Cooling Economizer
An energy saving control is adopted which uses fresh cold air from the outdoors for cooling the
intermediate seasons. The compressor is not used during this control, which results in outstanding
energy saving.
• Three Different Economizer Cooling Controls
In order to optimize energy savings, EconoFresh can manage three types of control: normal cooling,
outdoor air cooling or fan cooling. Each type is managed according to the outdoor air temperature.
• Comfort Control
When Thermo OFF is requested, EconoFresh compares temperatures in order to offer a comfortable
environment in the room. EconoFresh control compares the set temperature (set in the wired controller)
and the inlet air temperature in the Indoor Unit, and requests Thermo ON under certain conditions, in
order to achieve the requested room temperature as soon as possible.
Standard Process in Heating Mode
Depending on the temperature of indoor air return, the damper remains either opened for a minimum
guaranteed intake of fresh air, or fully closed for 10 minutes. After this time, the damper is opened for a
minimum guaranteed intake of fresh air intake; this opening can be set through the d7 setting (7% or more
of the total outlet air).
