Operation on demand (start-up / shut-down) is performed by the same
sensor which is used in the control of the “Air quality function”.
A room sensor with the analogue output (0...10V DC) should be designed
for this function.
6.7.7. Recirculation control
The air handling unit with a mixing section has the extract air recirculation function, i. e. when the extract air flow
is returned to the room.
Recirculation can be performed according to:
• Room air quality
1
. In this case air quality sensor should be additionally connected to the controller terminals
(B8) “Air quality sensor”. The user can set the air quality value to be maintained so that when it is exceeded,
the recirculation damper is closed and the unit supplies more fresh air.
Recirculation according to air quality is performed by the same sensor
which is used in the control of the “Air quality function”.
• External temperature. Recirculation will be controlled to the external temperature curve set by the user, e. g.:
Recirculated air,
%
Outdoor
temperature,
С
• Weekly schedule. The user can set an automatic program for the whole week where the following can be
assigned: the moment and percentage of required recirculation. The recirculation schedule is set with the
scheduling menu.
• External contact.
If a device (switch, relay, timer, etc.) is connected to the external control terminals (IN4)
(see Picture 5.3 b), recirculation will be activated when the contacts are short-circuited and will operate at the
recirculated/fresh air ratio set by the user.
6.7.8. Humidity control
Humidity control function is designed for maintenance of air humidity determined by the user. For proper operation
of the function one or two additional humidity sensors shall be connected, depending on where humidity will be
maintained. There are two modes for maintenance of humidity:
• Supply air. The determined humidity of supply air is maintained, using the supply air duct humidity sensor (B9).
