Figure 14: Control Location (Space Humidification)
1 Humidity Control

NHRS can be modulating, On/Off, or a humidity transducer.

Locate in room being humidified but not in discharge zone of blower pack(s).

Mount on indoor wall in area representative of room humidity (draft, doorways,
sunlight, or overhang such as shelf can affect reading).
2 High Limit Humidistat (not shown)

Install a high limit On/Off humidistat in area representative of room humidity.
3 Outdoor Temperature Sensor (not shown)

Mount outside in area representing outdoor air temperature.
Note: Regardless of selecting on/off or modulating control method, Nortec humidifiers must have a
closed circuit across its 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.
