SYSTEM OPERATION

The room is heated by a hot air generator (1) or similar
heating system, which channels heated air into the
occupied area (2). Since hot air has a lower specific
weight than cold air, it rises towards the ceiling, where
it accumulates.
The VORT DELTA T system compensates for the
increase in temperature difference between floor and
ceiling. The Nordik International Plus fans (3) are
controlled so that hot air is directed from the ceiling
downward towards the occupied area. Once the

INSTALLATION

The VORT DELTA T must conform to current IEE
wiring regulations. Installation must only be carried
out by a professionally qualified electrician.
Conductors must only be inserted from below using
the cable holder provided. The connections must be
as shown in the diagram. The VORT DELTA T can
control up to 15 appliances (6 Amps max).
The transparent VORT DELTA T cover should be
attached after installation or adjustment using the
screw provided. The system is completely automatic

The VORT DELTA T can be used with existing heating
systems, regardless of their type. No user intervention
is required for control of the heating system, since
VORT DELTA T functions on the basis of current and
measured parameters, and takes into account
external factors such as solar radiation, cold air

point in the room, preferably in a central position;
openings in the ceiling or insulating bridges in the
vicinity could cause false data measurement and
faulty system operation.
The floor sensor should be installed in a position at
the occupied area. Open doors or windows or
sudden cold bridges acting directly on the floor
sensor could cause malfunctioning of Nordik
International Plus fans.
The sensor must not be covered. Neither sensor
should be mounted on metal supports connected
with the exterior (cold bridge).
The semiconductor sensor can be connected
using a common 2-wire (0.5 mm
