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.
