Cooperation with air parameters
sensors
The controller has integrated software
modules allowing cooperation of recuperation
central with selected types of air parameters
sensors: digital carbon dioxide level sensor
(CO
2
), analog carbon dioxide level sensor
(CO
2
) or analog humidity sensor.
8.1
Digital CO
2
level sensor
Digital CO
2
level sensor is made to constantly
monitor concentration of carbon dioxide in the
room. With the moment of exceeding a preset
CO
2
value sensor contact output status
changes. Controller responds on this status
change by proper adjustment of fans speed:
air supply and exhaust. It provides faster air
exchange in the room, which results in
lowering carbon dioxide concentration in the
air. After stopping the signal from the sensor
and passing the support time controller sets
fans speed according with chosen operation
mode.
8.2
Analog CO
2
level sensor
Analog CO
2
level sensor is made to constantly
monitor concentration of carbon dioxide in the
room. If the sensor detects high CO
2
concentration the controller will immediately
override fans speed. It will provide faster air
exchange in the room, which results in
lowering carbon dioxide concentration in the
air. However, if the sensor detects too low CO
2
concentration, controller will immediately
lower fans speed. It will provide lowering the
amount of outdoor air intake, resulting in
successive increase of CO
2
concentration.
When CO
2
concentration in the air reaches
nominal value the controller will get back to
normal operation mode and set fans speeds
according to currently selected operation
mode.
8.3
Analog humidity sensor
Analog humidity sensor is made to constantly
monitor concentration of water vapor in the
room. If the sensor detects too high humidity
level, controller will immediately override
increase of fans speed. It will provide faster
air exchange in the room resulting in fast
humidity excess removal. However, if the
sensor detects too low humidity, the controller
will immediately override lowering fans speed.
This will provide in lowering outdoor air intake
resulting in increasing humidity. When
humidity level reaches nominal value the
controller will get back to normal operation
mode and set fans speeds according to
currently selected operation mode.
Settings regarding support of digital sensor,
fans speed override and support time are in
the installer menu and should be adjusted
during installation of recuperation central.
Settings regarding operation of analog CO
2
sensor are in installer menu and should be
adjusted during installation of recuperation
central.
Settings regarding operation of analog
humidity sensor are in installer menu and
should be adjusted during installation of
recuperation central.
