4.4.3.2 Space Distribution Control Design
When distributing steam directly into the conditioned environment the humidification system will require
a wall-mounted On/Off humidistat or transducer (RH sensor). Condair also recommends a high limit
switch. Environments with exterior walls should consider using an outdoor temperature sensor to prevent
condensation on windows/walls.
The following installation requirement must be observed when using humidity controllers in a space
distribution system:
Wall-mounted controls should be located in an area that is not exposed to infiltrating air, and where
there are no discharge diffusers or localized variations in temperatures.
