Operating the ventilation unit
9.1
Selecting the ventilation level/program
There are various ways to select a ventilation level or ventilation program:
— using the buttons of the membrane touch pad (items 1 to 5 in Fig. 12 on page 23)
on the ventilation unit (see section 7.1.1 on page 24)
— using the InControl pushbutton sensor (see section 7.2 on page 26)
NOTICE
— If there are multiple ventilation units of the same type connected to an InControl
pushbutton sensor, the same ventilation program is activated for all the ventila-
tion units.
— If there are multiple ventilation units of the same type with humidity and/or CO

control/automatic mode connected to an InControl pushbutton sensor, each
ventilation unit regulates the air exchange on the basis of its own measured
values.
— using the three-step rotary switch with zero position (see section 7.3 on page 28)
The ventilation unit always carries out the most recently made selection.
9.2
Setting the ventilation unit to Standby mode
You can set the ventilation unit to Standby mode. This triggers the following actions:
— The current ventilation mode is ended.
— The ventilation unit continues to be supplied with power.
— The air flaps close.
Simply activate the desired ventilation program again to leave Standby mode.
NOTICE
It is not a good idea to leave the ventilation unit in Standby mode for long periods (see
section “6 Rules for correct usage” on page 21).
9.2.1 Activating Standby mode with the InControl pushbutton sensor
► Hold down the button for the “Reduced ventilation (people absent)” program on the
InControl pushbutton sensor (see section 7.2 on page 26) for at least 3 seconds.
NOTICE
Standby mode is disabled at the factory in association with the “Mains switch without
function” option, type: M-WRG-O/NOF. In this case, Standby mode cannot be activated
using the InControl pushbutton sensor.
9.2.2 Activating Standby mode with the three-step rotary switch
► Turn the three-step rotary switch to position 0.
