• The devices are suitable for wall mounting and panel
mounting.
•5HFRPPHQGHG KHLJKW P DERYH WKH ȵRRU
• Do not mount the devices in recesses, shelves, behind
curtains or doors, or above or near heat sources.
• Avoid direct solar radiation and drafts.
• Seal the conduit box or the installation tube if any, as
DLU FXUUHQWV FDQ D΋HFW VHQVRU UHDGLQJV
• Adhere to designated ambient conditions.
The cable to the control panel is laid between the
ventilation unit and the control panel.
The control panel is designed for concealed installation
above the wallbox.
The included cable is 12 meters. If you need a longer
signal cable, order our 24 m cable. Art.no. 118258.
!
The cable to the CI 70 control panel
must be at least 30 cm from the
230 V cable (including dimmers,
thermostats, etc.). Power cables
must cross the CI 70 signal cable
at a right angle. For concealed
installation, the cable is laid in 16
mm cable tubes.
When you have installed the signal
cable, pull out all cable at the CI
70 panel to avoid surplus signal
cable at the ventilation unit. A roll
of cable at the unit may cause
disruption. Cut the signal cable to
the right length before the next
step.
CI 70 control panel must be
connected to the ventilation unit
before powered ON.
After power ON it takes approx.
3 min before the control panel
is in operation.

Home page
NB. The fan speeds are factory-set
to: Away 50%, Home 75% and High
100%.
High must always be set higher
than Home, which must be set
higher than Away.
For example, if you want to set
Home lower than 50%, you must
first reduce Away so it is always
lower than Home. The same
applies between Home and High.
i
Home: This is a constant mode and is Intended for normal use when the
building is occupied.
Away: This is a constant mode and is intended for use when the building is
unoccupied for longer periods. You can also set a delayed start, which can be
useful if you just got out of the shower before you leave the house.
High: This can be both a constant mode and a temporary mode with a set
duration. It is intended for use when a higher ventilation demand is temporarily
required.
Fireplace: This is only available as a temporary mode with a set duration.
