4.2 Setting Parameters
The parameters for all operating modes feature a default value. These
values can be restored by running the “Factory set” operation. See the
table of parameters for details of the default values and settings.
Initially at least the following parameters need to be checked/set:
SET POINT: • erent set points
are used. To set these, access (SET button – 5 seconds) the mode
for setting the parameters and set the corresponding values.
For the current mode only, the value can be accessed directly

The same is true for models without the RTC function.
When the time bands are set, the CLOCK symbol is shown on the
display.
PARAMETERS:
• check/set the other parameters (dIF, dS1,...) based on
the mode used.

Note: If AUTO humidity mode is enabled, the humidity setpoint
is reduced to 10% when the outdoor temperature is greater than
50° F. Disable AUTO for operation in warm outdoor temperatures.

4.3 AUTO humidity control
In addition to the modes featured by the control algorithms, the humidity
can be controlled automatically, based on the reading of the outside
temperature sensor. The aim of this type of control is to simplify the
setting of the GFX50, changing the humidity control according to the
outside environmental conditions and therefore minimize the discomfort
of the user when moving into/out of the air-conditioned environment.
This operating mode is selected by setting parameter AUT.
According to the level set using the up/down buttons, with a value from
