Temperature sensor connection
and installation
Use only the following temperature sensors of
NTC10K type. Using different sensor types is
forbidden.
Sensors cables can be extended by a cable
with cross-sectional area min. 0,5 mm
2
, a
total cable length max. 15 m. Make a hole in
the ventilation duct in the place designated for
temperature measurement, put on the rubber
sleeve (1) and install the sensor. The sensor
should be attached to the duct using tape to
ventilation insulation (2), as shown in the
figure below.
It is not allowed to flood sensors with water/oil. Sensor
cables should be isolated from mains lines and heat
sources to avoid false temperature readings. Minimum
spacing between sensor cables should be min. 400 mm.
The sensors must be connected to the
controller according to the electrical scheme.

Temperature sensors testing
Sensors are tested by measuring resistance in
given temperature. Temperatures with
corresponding resistance values are provided
in table below.

Connecting of differential pressure
sensors
The module operates only with ecoPRESS IN1
differential pressure sensors. Using different
sensor types is forbidden. Sensors should be
placed on the module board at marked place
(Pressure Sensor 1 and Pressure Sensor 2) by
inserting sensor pins into module sockets, in
accordance with figure below.
Mounting the ecoPRESS IN1 pressure sensors: 1 -
M2.5 x 25 screw + nut, 2 - adapter connector pins,
3 - sensor, 4 - Ø4 mm pressure pipe, (+) - pressure
before laminar flow limiter, (-)
–
pressure behind
laminar flow limiter.
Pressure sensors must be firmly mounted to
the module board with screws, otherwise
measurement errors might occur due to
mechanical tensions. The pressure tubes
connected to the sensor's connectors should
be inserted into the ventilation duct with a
laminar flow limiter, maintaining proper
connection of pressure values before (+) and
after (-) this limiter. The pressure tubes must
be properly sealed and secured against being
pulling out. When sensors are installed

sensors.
Sensors must be properly mounted and
protected against loosening from the
ventilation ducts according to installation
manufacturer recommendations.
