SYSTEM OVERVIEW
inVENTer Connect controller platform | Operating instructions
2.2 Connect inner cover
The Connect inner cover (in the following text "inner cov-
er") is a network inner cover (radio or RS485 data cable)
and replaces the standard inner covers of the iV-Smart+,
iV14-Zero, iV-Light and iV-Compact ventilation units to
facilitate integration into the inVENTer Connect network.
In addition to the radio interface, the inner covers have
local control electronics, a power supply unit and an
automatic closing flap.
It controls the speed and direction of each decentralised
inVENTer ventilation unit with heat recovery connected
to it.
Paired (by radio or by cable) with the controller, it is controlled by the latter.
For initial setup and to integrate the inner cover into the ventilation system (
3.2,
3.3),
a button and associated LED are used which provide feedback or can display the device status.
Function
If an inner cover is paired to the controller, it controls the associated ventilation unit (one ventila-
tion unit per inner cover) using the information received from the controller. It controls 4 ventilation
modes with different speed levels in which the respective inVENTer ventilation unit then operates:
• Heat recovery
In heat recovery mode, each ventilation unit changes direction (supply air / extract air) every
70 seconds. Ventilation units can be "paired" so that two units form a pair that works in opposite
phases, i.e. one ventilation unit works in ventilation while the other one vents. After 70 seconds,
both units switch over to the other direction.
• Unidirectional ventilation
In this ventilation mode, the units in a ventilation zone operate with a constant air flow direction,
with one unit per pair of units operating in the supply air direction and the other in the extract air
direction.
• Pause function
The ventilation units pause for a pre-defined period of time. The automatic closing flap is closed
for this time. Operation is then continued on the basis of the ventilation profile selected for this
ventilation zone (saved in the controller, ventilation profile tables
Annex).
•
Switch off
The ventilation units are switched off and the closing flaps close.
There are four levels for the ventilation units, which define the units' speed and air flow. These can
be adapted by users to their personal values.
The factory standard settings for the ventilation levels are:
• Level 1 – 25 %
• Level 2 – 35 %
• Level 3 – 50 %
• Level 4 – 100 %
