Vari-Green Controls
Motor on Dial and 0-10VDC control options are only available on the basic VG-BLDC motor technology and more
information on these controls can be found in that section of the IOM.
The following controls are available on any motor technology option that uses a Vari-Green HOA:
Hand/Off/Auto: this is the basis of the VG-BLDC advanced
motor assembly or Control Box (VG-SynRM or Induction motor with
VFD controls). There are no additional ship loose controls included
in this option (other than the control box may ship loose). This
option comes defaulted to look for a remote 0-10VDC signal from
an external source (auto remote). If this fan is desired to operate
at a single speed without an additional external signal, press the
mode button until HAND mode appears. To change speed, press
the up or down arrows until the desired speed is acquired. To save
the new speed, press the MODE button again.
Adding external or remote 0-10VDC signal to HOA:
When connecting ship loose Vari-Green or other 0-10VDC
controls, you must wire them back to the HOA. The location of
connections is shown on the image to the right.
See fan submittal for more details on the controls and wiring as configured.
If additional information on the HOA is required, refer to the 24VAC/DC HOA Controller User and Service Manual,
Document 485093.
The following options include additional ship loose controls:
Remote Dial: This control option adds a ship loose Dial for a remote speed control
installation. The Remote Dial mounts in a standard single gang 2x4 junction box and
requires a 3-wire control cable to be wired back to the HOA controller.
To get additional information on the Vari-Green Remote Dial, see the Vari-Green Motor and
Controls IOM, Document 473681.
Touch Remote: Like the Remote Dial option, the Touch Remote adds a ship loose push
button control for remote installation. This control also mounts in a standard single gang 2x4
junction box and requires a 3-wire control cable to be wired back to the HOA controller.
To get additional information on the Vari-Green Touch Remote, see the Vari-Green Motor and
Controls IOM, Document 473681.
