Temperature sensor
6.1.1.
Standard positioning
The temperature sensor is located on the lowest part of the board.
This sensor is located at the end of a coiled pigtail 3cm long conductor to
minimize thermal bridging with the board and thus reduce the thermal
inertia. In addition, the metal used is constantan. This alloy is a good
electrical conductor and a good thermal insulator which further reduces
the thermal the thermal bridge with the board. So in case of sudden
temperature change (window opening), the probe reacted very quickly.
For an accurate measurement, it is necessary that the sensor (the little
black ball) be in the air stream.
Pull lightly on the sensor to make it exceed by 3 mm from the dished
shape recess in the plastic housing. Do not overpass 6mm to avoid
touching the plastic cover.
A gentle stream of air is generated by the heating of the CO2 and VOCs
sensors located in the upper part. The incoming air is immediately
measured by the temperature sensor.

High performance positioning
The here under optimum positioning of the temperature sensor eliminates thermal phenomena in the
containment housing and improves accuracy.

Power Supply
7.1.1.
Power Supply Characteristics
Use a power supply between 12 and 24V AC or 15 and 33V DC with a fluctuation of max
value of less than 10%, preferably a DIN rail regulated one.
Make sure the voltage does not overpass 24V AC or 33V DC before connecting to the
E4000-NG
probe.
Take into account the voltage drop in the cable to assess the consumption of each sensor.
Temperature sensor
Stretch the twisted cable of the sensor in
pulling it down. Put the cover from the
bottom by inserting the sensor into the
vent.
Check visually and make sure not to
exceed the border for aesthetic reasons.
