Accessories, control technology
The design of the ventilation system is
dependent on the accessories selected. The
following accessories are available:
• Boost timer (105TK). A push button
which can be installed at a desired place
and with which the Boost operating mode
can be activated.
• Humidity sensor (117KKH). the sensor
detects when the relative humidity exceeds
the preset limit value and activates the
Boost operating mode.
• Fireplace switch (102TKC). A push button
which can be installed e.g. beside the fire-
place and with which the fireplace function
can be activated.
• Presence detector (102LT). The sensor de-
tects movements in the home and increases
the fan speed to the Boost operating mode.
• Carbon dioxide sensor (117HDL). The
sensor increases the fan speed from the
Home operating mode to the Boost operat-
ing mode when the current carbon dioxide
content in the air exceeds the preset limit
value, e.g. 900 ppm.
• Negative pressure compensation
(117PK2). A separate sensor (e.g. one
that senses the difference in pressure)
can transmit a signal to the controller to
increase the ventilation unit's supply air
flow to restore balance when negative
pressure has developed in the home while
using a cooker hood, power roof ventilator
or central vacuum cleaner.
• Supervision (DDC). Certain functions can
be controlled from an automated building
management system. A more detailed
description is given in the technical instruc-
tion manual.
• Home/Away switch. A switch which is
usually installed next to the front door
and starts the Away operating mode.
The switch can be a standard switch of
optional type.
