- This runs indoor air conditioning.
-
Initial external air inlet setting is 30% of the air
supply during the air conditioning and this can be
changed by the user. But, when the damper actuator
is installed on AHU, the setting can be changed.
- This runs the indoor heating.
-
Initial external air inlet setting is 30% of the air
supply during the heating and this can be changed
by the user. But, when the damper actuator is
installed on AHU, the setting can be changed.
-
This is the operating function to run indoor air
conditioning by controlling multiple outdoor units by
comparing the enthalpy of the indoor/outdoor air.
-
During the power save operation, the operation switches
between partial air conditioning operation (Controlling
multiple outdoor units) and external air conditioning
operation (Outdoor unit OFF, 100% external air flow).
-
This is operating function is mainly used in between
seasons. But if there is no OA temperature/humidity
sensor and RA temperature/humidity sensor on the
AHU, the power save operation cannot be selected.
-
This is the operating function to remove the indoor
humidity when the humidity level indoor is excessive.
-
During the dehumidifier operation, the set value is
50%RH and the user cannot change this setting. But
if there is no OA temperature/humidity sensor and
RA temperature/humidity sensor on the AHU, the
dehumidifier operation cannot be selected.
-
This is the operating function to control the humidity to
the set value by detecting the indoor humidity level.
- This can be selected during heating operation.
But if there is no humidifier/humidifying valve and
RA temperature/humidity sensor on the AHU, the
humidifier operation cannot be selected.
- When the mixing temperature during the heating
operation is below the set value (5°C),
preheating device automatically operates. The
preheating device and mixing temperature
sensor must be installed on AHU for this to
operate automatically.
-
This is the operating function to control the amount of
external air flow so that the CO2 level is controlled
within the set level by detecting the indoor CO2 level.
- The initial CO2 level is set to 1000ppm, and can
be changed by the user.
-
This function operates when auto ventilator
(Additional operation) is selected during air
conditioning or heating operation. But if there is no
CO2 sensor and damper actuator on the AHU, the
auto ventilator operation cannot be selected.
