This guide will inform the electrician on proper wiring and installation procedures
and, will also inform the user on how to use the MVS-1C controller.
The manufacturer recommends that the following installation instructions be
followed to as closely as possible, and that all work be performed by a certified
electrician. Failure to do so may void the warranty.
Description
The MVS-1C controller is designed to manually control a variable speed output.
A Speed Selector is used to adjust the speed of the variable output. That Speed
Selector can also turn off the output by turning it counter-clockwise. The
controller operates on 115/230V and 50/60Hz.
The MVS-1C comes in a PVC non-corrosive enclosure that is protected from
dust and humidity. The MVS-1C is covered by a complete two-year warranty.
Unpacking
Unpack the MVS-1C module and inspect contents for damage. Should the
contents appear to be damaged, contact your local distributor to return the
equipment.
The package should contain the following standard items:
1 MVS-1C
1 Mounting Plate Kit

General installation guidelines
-It is recommended to install the unit in a hallway to limit the MVS-1C exposure to
noxious gases.
-In order to avoid condensation problems inside the MVS-1C, it is recommended to
install the module on an inside wall. If it is not possible, use spacers to have an air
gap between the wall and the controller.
-The MVS-1C should be installed in easy-access location but away from damaging
elements (heat, cold, water, direct sunlight…).
-Do not install the MVS-1C near high-voltage equipment, power supply or
transformer.
-When installing the mounting plates onto the back of the enclosure, makes sure to
use a regular screw driver (DO NOT use a drill or electric screw driver) to screw the
tap screws into the plastic holes.
Wiring Procedure
1. Open the MVS-1C controller enclosure.
2. Verify the technical specifications to know which wire to use.
3. Connect the equipment to the 2 black terminal block identified as FAN as shown
in figure 1.
4. Connect the power source to the 2 black terminal block identified as LINE as
shown in figure 1.
5. Make sure that the voltage selector switch is set to the correct voltage before
powering up the MVS-1C (refer to figure 2 for the location of the switch).
6. Power up the MVS-1C controller. Verify that the controller operates correctly.
7. Close the MVS-1C enclosure. Don’t forget to put a security screw or a padlock.

1. Minimum Speed Potentiometer
This potentiometer is used to adjust the Minimum Speed of the fan. That
Minimum Speed will be the speed of the output when the Speed Selector is set to MIN
2. Voltage Selection Switch
This switch is used to select the input voltage value (115V or 230V).

The MVS-1C controller will make the fan modulate according to the Speed Selector
on the faceplate (refer to figure 3). It is also possible to adjust the Minimum Speed
with the potentiometer located inside the controller box on the electronic board (refer
to figure 2). That Minimum Speed will be the speed of the output when the Speed
Selector is set to MIN.
Here is a description of the MVS-1C operation.
- To turn on or off the variable output, use the Speed Selector located on the
faceplate (refer to figure 3)
-Also, use the Speed Selector to increase or decrease the variable output speed.
When the Speed Selector is set to MIN, the Minimum Speed set by the
potentiometer inside the controller will be used (refer to figure 2).
