Storage

If the controller is stored for any length of time prior to instal-

lation, store controller in the original packaging inside from the

weather and keep temperature between -22°F to 122°F (-30°C

to 50°C).

Installation

The VFRSC can be mounted in a electrical box with the two

screws provided. This device requires a 24VAC/DC power

supply. VFRSC is UL Listed when mounted in UL Listed en-

closure. Minimum transformer output of 1VA.

Location and Maintenance

Consider the following points while choosing a location for

the Vari-Flow Remote Speed Controller.

• Less than 100 feet of wiring to motor or to VFABK.

• Install the controller indoors.

• Do not place the controller on the floor.

• Maintain a temperature between 30°F to 110°F (-1°C to

43°C). A temperature beyond this range may cause conden-

sation and sweating of metal parts.

• Maintain a low humidity, dry, and clean atmosphere. Ensure

that the controller is not in the path of blowing dust, rain, or

snow.

Operation

This device outputs a 0-10v signal voltage. The dial does not

indicate voltage, but a range of available voltage from max to

min. Vari-Flow motors operate on a 2-10V signal. Below 2V,

the motor stops but is still powered.
