Return air quality probe (duct-mounted).
Probe installed on the master unit of the SHRD shared network.
This probe must be fixed to the
interior wall of the room to be
conditioned, at ca. 1.5 m height in
the room and at least 50 cm from
the next wall.
It should never be mounted:

- In the radiation range of heat sources and lighting bodies e.g.
spotlights.
- In areas exposed to direct solar radiation.
Duct-mounted
This version can be connected to the air duct in these two ways:
Electrical connection
This probe (S10) is confi gured as analogue output 4…20 mA (0..2000
ppm), in the analogue input B10 of the control board). Recommended
cable section: 1,5 mm
2.
Cleaning and maintenance
When cleaning the instrument do not use ethyl alcohol, hydrocarbons
(petrol), ammonia and derivatives. Use neutral detergents and water.
Periodically check the aeration slits on the sensor to make sure that
