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 function switch (102TKC).A push
button that can be installed e.g. beside the
fireplace and with which the fireplace func-
tion 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
automatic control system controls the
ventilation strength variably according to
the carbon dioxide level in the home.
• Negative pressure compensation
(117PK2).A separate sensor (e.g. one that
senses the difference in pressure) can
transmit a signal to the controller that
compensates the airflows 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.
• Modbus. Permits connection of the
ventilation unit to an automated building
management system.
• 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.
Swegon reserves the right to alter specifications.
Factory-fitted Smart accessories
• Automatic humidity control. An intel-
ligent function that boosts the ventilation
when the moisture level increases.
• Automatic Home/Away/Boost control.
The control function governs the ventila-
tion strength variably according to the
carbon dioxide level in the home.
• Automatic air quality control + air
humidity control. The function boosts the
ventilation according to the VOC level in
the home.
