Product overview
For room humidity control with continuous limitation of the supply air humidity (System 2), the sensors
should be placed as follows (see
• The
air flow monitor "B2"
(optional accessory) must be installed
in front
of the Condair DS steam
distribution unit with a
minimum distance of 200 mm to the reduction on the inlet side
in the
supply air duct.
• The
maximum humidistat "B1"
must be installed
behind
the Condair DS steam distribution unit with
a
minimum distance of 250 mm to the reduction on the outlet side
and a
maximum distance
of 1000 mm
into the supply air duct.
• The
humidity sensor for supply air limitation "A2"
(Signal Y2) must be installed in the supply air
duct with a
minimum distance of 100 mm
from the maximum humidistat "B2".
• The h
umidity sensor for humidity regulator "A1"
(Signal Y1) must be installed in the extract air
duct of the room to be humidified.
This humidity control system requires either the PI continuous controller integrated in the Condair RH
or an external PI continuous controller with two signal inputs.
Recommended settings for the maximum humidistat and the humidity sensors:
– Maximum humidistat "B1":
80 %rh
– Humidity sensor "A1":
recommended 45 %rh (min. 40 %rF to max. 50 %rF)
– Humidity sensor "A2":
Lower limit: 60%, Upper limit: 80%
