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:
M O U .f e d e g n a r r e t e m a r a p e h t f o n o it p ir c s e d e d o c
CAL+ Int
Inside temperature calibration, digital sensor or NTC
Within a maximum of ± 10 °C
-10 to 10 0.0 °C
CAL+ ESt
Outside temperature calibration, NTC sensor
Within a maximum of ± 10 °C
-10 to 10 0.0 °C
CAL+HUn
Digital humidity sensor calibration.
Within a maximum of ± 15% rH
-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,
to the main menu. Once having set the timer, pressing the NIGHT button
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
5.1 (H) humidity control
This type of control is used to send a start signal to a humidifier or
dehumidifier. The modulating output can only be used for humidification
control. Examples of using modulating output:
•
for proportional humidity control of GeneralAire Elite Steam humidifiers
as an additional step to the relay for humidity control.

Tab. 5.a
This section describes the humidity control modes available. The
control modes are based on parameters divided into two levels:
Level 1, basic:
•
main settings, always required;
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 differentials. In each operating mode, the links between the
various basic and avanced levels are specified.
if level 1 is active, the level 2 parameters are not used but rather
•
replaced by the default values or by the link value with the level 1
parameters; the supervisor can read and set the level 2 parameters that
ectively used for the control functions.
ectively used when level 2 is activated.
