System Setup Schematic

1  On/Off humidistat, modulating humidistat, or humidity sensor

2  On/Off high limit humidistat, modulating humidistat, or humidity sensor

3  Air proving switch

Notes:

• 

 Humidity sensors and humidistats (1) can be modulating or On/Off. Preferred location is in the return 

duct, as the supply air is well mixed with the room air at this location. Avoid placing near discharge 

diffuser, near doorways, in sunlight, or in airflow “dead-zones”.

• 

 Locate the high limit humidistat or humidity sensor (2) downstream of the humidifier’s distributor so that 

it can sense a duct that is over-humidified. Recommended setting is 85% RH. Locate it downstream 

of the distributor – at least 5x the absorption distance away. If the absorption distance is not known, 

locate it at least 10 feet (3 m) downstream from the distributor. Can be a humidistat (modulating or 

On/Off), or a humidity sensor.

• 

 Locate the air proving switch (3) in the same duct as the humidifier’s distributor so that it can sense 

air flow (or lack thereof).

5.7.2  Permissible Control Signal Inputs

Table 8

 shows the different permissible control signal inputs the Nortec EL steam humidifier can handle.
