Upper humidification limit:
To enable the high limit of humidification set the following parameters:
- set high limit control of humidity
147
=1,
- pair the supply humidity sensor with the AI3 input:
023
=6 and put the JP1 jumper in the “3-2” position
- define the maximum limit setpoint
148
and the humidity limit proportional band
149
.

If the supply humidity goes above the high limit humidity setpoint
148
, the modulating humidifier is controlled considering the
lowest value between the theoretical output of the humidification control and the theoretical value of the Lim_max_hum limit.
