D. Installation - Ventilation
For every CO2 intervent. step in excess when the Block is activated (Maximun CO2), the temperature
Set of the Ventilation is decrease of value as set in Ventilation set decr., until a maximum value set in
Maximum set decr.
This reduction also applies to the Heating set.
i.e. when considering the following sets:
Ventilation = 25.0° (vedi par. C.1)
Maximun CO2 = 2800
pm
CO2 intervent. step = 50
pm
Ventilation set decr. = 0.2°
Maximum set decr. = 1.0°
Below 2800 ppm of ambient C02 (Maximun CO2) the Ventilation temperature set will be 25.0°, at
2800 ppm of ambient C02 will be 24.8° (25.0°-0.2°= 24.8°), due to decrease of 0.2° (Ventilation set
decr.) for every extra 50 ppm (CO2 intervent. step) of ambient C02, up to a maximum decrease of 1.0°
(Maximum set decr.) which will bring temperature set of Ventilation= 24.0° at 3000 ppm of CO2.

For every NH3 intervent. step in excess when the Block is activated (Maximun NH3), the temperature
Set of the Ventilation is decrease of value as set in Ventilation set decr., until a maximum value set in
Maximum set decr.
This reduction also applies to the Heating set.
i.e. when considering the following sets:
Ventilation = 25.0° (vedi par. C.1)
Maximum NH3 = 18
pm
NH3 intervent. step = 0.5
pm
Ventilation set decr. = 0.2°
Maximum set decr. = 1.0°
Below 18 ppm of ambient NH3 (Maximun NH3) the Ventilation temperature set will be 25.0°, at 18
ppm of ambient NH3 will be 24.8° (25.0°-0.2°= 24.8°), due to decrease of 0.2° (Ventilation set decr.)
for every extra 0,5 ppm (NH3 intervent. step) of ambient NH3, up to a maximum decrease of 1.0°
(Maximum set decr.) which will bring temperature set of Ventilation= 24.0° at 20 ppm of NH3.
