The SIRIUS-CL(S) is a ventilation computer which is applied in houses where the ventilation may be controlled proportionally
and / or in stages. To maintain the negative pressure constant, it is possible to control the air inlet by making use of an extra negative pressure sensor. The heating and cooling are controlled by a relay contact. If there is a need for an extra air humidity sensor, the cooling can be switched off when the relative air humidity becomes too high.
