NOTE: Skip this section if you do not have a humidifier or a dehu-
midifier connected to the controller.
The humidity level can be set manually or automatically.
The humidity level is set by the user (5 to 60%).

Press the Hum button until MAN appears on the screen.

Press one of the buttons to adjust the humidity level.

Press the button.
The humidity level is set by the controller based on the outdoor tem-
perature to prevent ice formation or condensation on the windows
while providing enough humidity for your comfort. However, the user
can apply an offset (-9 to 9%). For example, the user can enter a
negative offset if there is still ice formation or condensation on the
windows.

Press the Hum button until AUTO appears on the screen. The
humidity level set by the controller is also displayed.

Press one of the buttons to enter or change the offset.

Press the button.
To turn the humidity control off:

Press the Hum button until OFF appears on the screen.

Press the button to save and exit the programming.
If you have connected an air exchanger to the controller, you can
set it in air exchange mode. In this mode, the air exchanger is acti-
vated to circulate air between indoors and outdoors regardless of
the indoor humidity level.
To activate the air exchange mode:

Press the Hum button until AIR appears on the screen.

Set the duration of the air exchange mode using the but-
tons. Select 10 - 90 minutes for a specific duration or On for an
indefinite length of time.

Press the button.
NOTE: If the air exchange mode has been set for a specific dura-
tion, the controller will revert to the mode in which it was previously
(humidity control mode or off) at the end of the air exchange mode.
To deactivate the air exchange mode:

Press the Hum button until one of the following appears on the
screen.
AUTO: The air exchanger is in humidity control mode — auto-
matic setting (see section 8.2).
MAN: The air exchanger is in humidity control mode — manual
setting (see section 8.1).
OFF: The air exchanger is Off.

Press the button to return to normal display.
If the controller is configured for a minimum air exchange time every
hour and that minimum has not already been attained by the end of
the hour, the air exchanger will be activated regardless of the indoor
humidity level (see page 8, item 19). Let’s say the minimum time is
set to 10 minutes. If the air exchanger has operated for 7 minutes
during a particular hour, it will automatically be activated for another
3 minutes by the end of that hour.
