External, supply, return and exhaust air dampers
If the airflows in the network of air distribution ducts are shut off when the machine is stopped, it is possible to fit dampers on the
external air intake, on the air supply line, on the air return line and on the exhaust air line. These are available as optional accessories.
The dampers are provided already mounted on the machine and with a servo drive for opening and closing. The control system of
the machine is connected to the servo drives which open and close the dampers according to the control logic.
The individual dampers can be purchased separately.

Increased useful static pressure of the fans
If a useful static head higher than the 250 Pa of the standard configuration is required for the air distribution ducts, an oversize
version of both the delivery fan and the return fan can be provided to increase the useful static pressure up to 400 Pa.
Note: for model 12500 only, in the case of pressure at 400 Pa, the delivery fan weighs 10 kg more than standard.
Variable speed heat recovery unit
The variable speed heat recovery unit is an optional component that can be installed in the place of the fixed speed heat
recovery unit.
Recirculation damper section (accessory)
If recirculation of a part of the extracted air is required, an additional section with motorised recirculation damper is available as an
accessory.
The recirculation damper can be controlled in different ways:
With CO2 probe, also available as an accessory. If the amount of CO2 in the extracted air exceeds the threshold set on the WIZARDX
controller, the external air intake damper will open and the recirculation damper will close, while if the CO2 remains below the
threshold the recirculation damper will open proportionally to reduce energy consumption.
Start-up with total recirculation. The unit starts up with the external air intake damper closed and the recirculation damper completely
open. When the set conditions are reached, the machine starts working entirely with external air.
Periodic air renewal: the machine forces 100% of external air at precise intervals set on the controller. For the assembly of the
"recirculation damper" section, see the chapter "JOINING THE SECTIONS".
The dimensional drawing of the "recirculation damper" section is supplied together with all the accompanying documentation.
