Figure 17: Control Location (In-Space Humidification)
Space Humidification
1 Humidity Control – Can be Modulating or On/Off humidistat
o Locate in room being humidified but not in discharge zone of blower pack.
o Mount in area representative of room humidity (draft, doorways, sunlight, or
overhang such as a shelf can affect reading).
2 High Limit Humidistat (not shown)
o Install an On/Off High Limit Humidistat in an area representative of room humidity.
3 Outdoor Temperature Sensor (not shown)
o Mount outside in area representing air temperature.
Note: Regardless of selecting on/off or modulating control method,
Nortec humidifiers must have a closed circuit across its on/off security
loop control terminal to operate. Nortec highly recommends the use of a
high limit humidistat and an air proving switch in series for this function.
