4.3 Selecting the control system
The various control systems
– System 1: Room humidity control
System 1 is suited for direct room humidification and air conditioning systems with mainly
recirculated air . The humidity sensor or humidistat respectively is preferably located in the room
itself or in the exhaust air duct.
A1 humidity sensor
B1 ventilation interlock
B2 airflow monitor
B3 safety humidistat
B4 humidistat
PI
E
External continuous controller
(e.g. PI controller)
Y input signal from A1
– 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.
