5.6 Notes on humidity control systems/humidity control
5.6.1 System 1 – Room humidity control
System 1 is suited for direct room humidification and air conditioning systems with mainly recir-
culated air . The humidity sensor or humidistat respectively is preferably located in the room itself or in
the exhaust air duct.

5.6.2 System 2 – Room humidity control with continuous limitation of the supply air
humidity
System 2 is suited for air conditioning systems with a large portion of supply air , low supply air
temperature
,
post-humidification
, or
variable airflow volume
. If the supply air hum idity exceeds the
preset value, the continuous limitation is effected prior to the room hum idity control.
The humidity sensor (A1) is preferably located in the exhaust air duct or in the room itself. The humidity
sensor (A2) for the limitation of the supply air humidity is located in the supply air duct after the steam
distribution pipe. This control system requires a continuous controller with the option to connect a second
humidity sensor.
Attention!
The continuous limitation of the supply air humidity is no substitute for the safety humi distat.
