Nu-Air ES Series Installation And Usage Manual

ES Series Controls: Installation & Usage Manual (Version 2.1, JN 2018)
A. Installing ES Series Controls: Preliminary Considerations
1. Your kit includes: 1 ES Series Control, 2 mounting screws, 1 wall plate with mounting screws.
2. ES Series controls are designed, if desired, to mount into a standard single- or multiple-gang switch
receptacle box. You may wire ES Series controls in Series or Parallel.
3. You may use a virtually unlimited number of ES "M" and "T" controls per installation.
4. You can use ES Series controls with Nu-Air Windsor Series controls and a variety of other
mechanical switches. Consult the HRV/ERV manual for details.
5. As a safety precaution, ensure that the HRV/ERV is unplugged before connecting any control
wires to it.
B. Procedure
1. Use a narrow-tipped flat-head screwdriver to secure control wires into the
terminal block located on the back of the ES Series control:
12 VDC—Red
B—Yellow
A—Green
GND—Black
2. At the HRV/ERV, screw the control wires into the removable 4-wire
terminal block, then secure the terminal block into the HRV/ERV circuit
board plug.
3. Install the appropriate wall plate. A single-switch wall plate is supplied
with your ES Series control.
Use 4-strand wire.
