10-10 Page 2 2008-02-18 1. CONTROLS A. STANDARD CONTROLLE RS (1) NORTEC has a wide range of modulation packages for use with the NHRS humidifiers. The packages all provide humidity controllers complete with point for accuracy up to ±3%. For accuracy u p to ±1% a high precision humidistat is required.
10-10 Page 3 2008-02-18 D. VARIABLE AIR VOLUME (VAV ) CONTROL SYSTEM (1) NORTEC offers several VAV control packages where VAV or variable duct temperature, air flow or humidity conditions require additional control fle xibility. 2. STANDARD FEAT URES AND BENEFITS (1) NORTEC NHRS humidifiers can be suited for all humidity control applications.
10-10 Page 4 2008-02-18 3. ELECTRICAL (1) Humidifiers require field wiring to the primary voltage terminal block. Power and fusing requirements are as indicated on the Specificat ion label. Wiring is fed through an electrical knockout in the bottom back of the electrical cabinet.
