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

Note: If AUTO humidity mode is enabled, the humidity setpoint

50° F. Disable AUTO for operation in warm outdoor temperatures.

4.4 Sensor calibration
To make up for any errors due to the length of the cables or the sensors connected, the controller features two parameters for calibrating the
values read by the sensors.
The following parameters are used:
CAL+ Int
CAL+ ESt
CAL+HUn
Inside temperature calibration, digital sensor or NTC
Within a maximum of ± 10 °C
Outside temperature calibration, NTC sensor
Within a maximum of ± 10 °C

-10 to 10 0.0 °C
-10 to 10 0.0 °C
-15 to 15 0.0 % rH
4.5 Additional functions
The controller, as well as the control algorithms for the various types of
applications (air-conditioners, boilers, heat pumps, condensing units,...),
features a series of additional functions, as described below.
Change night/day mode manually (NIGHT)
This activates the opposite function to the current (night if day or day if
night), for the set time.
Pressing the NIGHT button once accesses the timer menu and displays
the duration.
To change the duration of the temporary mode use the UP/DOWN
buttons.
To change the value of the timer permanently, access the Prg menu and set
parameter SLP. To set the current timer to zero and return the instrument
to the original mode, press the NIGHT button, the remaining time is
displayed, then press DOWN until reaching the value 0. The instrument,

displays the time remaining on the timer. This value can be changed at
any time.
To exit the menu press the NIGHT button again.
5. FUNCTIONS
This section describes the humidity control modes available. The
control modes are based on parameters divided into two levels:
• main settings, always required;
Level 1, basic:
Level 2, advanced:
• used to customize the features of the controller.
Important note: Some parameters included in the advanced
level, are forced to take on default values in the basic level or are
linked to other parameters in the basic level. This especially applies to the
control dierentials. In each operating mode, the links between the
various basic and avanced levels are specied.

5.1 (H) humidity control
This type of control is used to send a start signal to a humidier or
dehumidier. The modulating output can only be used for humidication
control. Examples of using modulating output:
•
for proportional humidity control of GeneralAire Elite Steam humidiers
as an additional step to the relay for humidity control.
