6.3.3 Installer menu – Save and Load and Reset Parameters
Fig. 6.9 Installer menu: Parameters
Save parameters
Used to save the currently programmed volume flow rates and all settings for inputs and outputs.
Before making any changes it is recommended that the existing parameters are saved using “Save
Parameters” menu. (Two memory slots are available).
Load parameters
Use “Load Parameters” menu in order to restore previously saved parameters. (Two memory slots available).
Reset parameters
Used to reset the all parameters for volume flow rates or for digital inputs and outputs to their default values.
Specify Unit
Used to load the unit configurations for the appropriate model. See unit rating plate for the model
description.
NOTE!
The ventilation unit is shipped with factory preset unit configuration.
•
When installing a new main circuit board, use “Specify Unit” menu to set the unit configuration.
Erase Error logs
Use “Erase Error logs” to clear all stored error messages (Up to 20 of the most recent faults are recorded and
can be viewed in the User menu “User Information – Error messages”).
6.3.4 Installer menu - Diagnostic Checks
The Diagnostic Checks menu can be used to check the operation of the individual outputs of the ventilation
unit.
Fig. 6.10 Installer menu: Diagnostic Checks

Section 4 – Installation
4.4.1 Thermal insulation
The ventilation unit must be installed within the warm space of the building.
Ducts installed in cold spaces must be adequately insulated.
WARNING:
•
The unit, air diffuser and air-duct system must be installed inside the building.
•
Connections at both ends of the fresh-air and exhaust-air ducts must be airtight and
covered with thermal insulation over the entire route. (To prevent condensation).
•
Any ducting that runs through unheated areas must also be fitted with thermal insulation,
in order to prevent heat loss.
4.4.2 Vibration isolation and sound insulation
•
The final connection to the unit must use flexible ducting to isolate any vibration noise getting into the
system.
•
If required, suitable silencers/attenuators should be used at appropriate positions in the duct system.
(This may also include suitable sound absorbing suspensions, clamps, brackets or other duct fittings).
•
Ducting passing through walls or ceilings should be “sealed in” using a suitable material.
•
Sound travelling through the ducting from one room to another is reduced when a radial duct system is
used.
4.4.3 Air inlets and outlets
Fresh air is drawn in and exhaust air goes out through exterior-wall grilles and/or roof cowls.
•
The Fresh air is generally cool, dry and free of odours.
•
The Fresh air draw in point should be at least 1.5 m above ground level if possible.
•
The Exhaust air point should be positioned far away from the Fresh air inlet.
(So that exhaust air does not
accidentally get drawn in to the fresh air intake).
•
Air inlets and outlets should be positioned in each room so that there is a good air flow through the room.
•
Position supply grilles so that they avoid direct drafts onto seats, chairs and beds, etc.
•
For unhindered air flow, areas such as hallways and corridors may require undercut doors or transfer
grilles.
4.5 Electrical installation
Natural Air 180 :
Connect the ventilation unit to a 230V/50Hz power supply, 5A fuse protection.
Natural Air 180 PH :
Connect the ventilation unit to a 230V/50Hz power supply, 13A fuse protection.
Optional sensors use a low voltage of 24V DC.
All cable inlets are located on the top cover of the ventilation unit.
4.5.1 Installation of the smoke detector bypass Link Wire
If an external smoke detector is NOT used, then a Link Wire MUST be fitted to the Main Connector PCB.
(Alternatively, if the External Sensors PCB is fitted, then the Link Wire can be fitted to the External Sensors PCB
instead).
