Digital inputs, terminals 5–8, are of extra-low voltage type. Ana-
logue inputs, terminal 37 has an input impedance of 66 k.Ω.
*COMPACT Unit: The designations apply to the right-hand version. In the left-hand version, the sensors change function and designation (the
components are named according to whether they are for supply air or extract air).
