For the humidifiers from 25 to 65 kg/h the electronic board without TAM is used: in its place are 2 terminals that are con-
nected to the TAM fitted in electrical panel on the unit.
Table 6.3.1 below shows the terminal blocks and the corresponding connections (functions and electrical specifications):
