SYSTEM
SPECIFICATIONS
Rain Sensor Input (Required) - (7.1)
Smoke Vent Input (Optional) - (7.4)
External Temperature Input (Required) - (7.5)
Heating Interlock Input (Optional) - (7.2)
Fire Alarm Input (Optional) - (7.3)
The Rain Sensor Input requires a normally open volt-free contact wired
between the “COM” and “NO” “Rain” terminals of J28 (upper level).
When the contact is closed the system will close the active louvres and
windows, but leave internal dampers on X-AIR systems and wall louvres in
their position based on the temperature/CO
2
to allow continued ventilation
in the space. If the ventilation system is a WINDCATCHER Classic or SOLA-
BOOST system, then the dampers will fully close on rain.
The Smoke Vent input requires a normally open volt-free contact wired between
the “COM” and “NO” terminals of the J33 “Smoke” terminals (upper level).
When the contact is closed all dampers, louvres, wall louvres and windows
will open to allow the escape of smoke.
The external temperature input requires a weather-proof temperature sensor
with a 0-10V output that maps to -10°C to +40°C, powered by 24V DC, connected
to J34. One such suitable sensor is the Titan Products part ref: TPVOS.
This should be located out of direct sunlight and away from any heat sources
that could affect the air temperature measurement (such as plant exhaust).
It is recommended that it is installed on a north facing façade of the building.
If it is located on any other façade it will require shielding by building soffits
or by a type of solar shielding.
It is used to adjust the seasonal strategy and protect ventilation systems
against snow/frost.
The Heating Interlock input requires a normally open volt-free contact wired
between the “COM” and “NO” terminals of the J28 “Heat” terminals (lower level).
When the contact is closed the system will limit all dampers, wall louvres
and windows to a maximum of 10% open as default. This may be altered
to anything in the range of 5% to 20% in 5% increments via the iNVent 2
configurator software.
The Fire Alarm input requires a normally open volt-free contact wired between
the “COM” and “NO” terminals of the J33 “Fire” terminals (lower level).
When the contact is closed all dampers, louvres, wall louvres and windows
will fully close.
Fault Output (Optional) - (7.6)
The fault output is a volt-free contact which when open indicates a fault has
occurred. Max rated voltage: 24V DC.
