1. INTRODUCTION
1.1. Precautions
WARNING: Read and save these in-
structions!
Safety may be jeopardized if the equipment
is used in a manner not specified by the
manufacturer. Carefully read and keep the
following instructions for future reference.
The room temperature where the module is
located must always remain between 32°F
and 104°F (0°C to 40°C). Indoor use only!
To avoid exposing the module to harmful
gases or excessive humidity, it is preferable
to install it in a corridor.
If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
Do not spray water on the module! In order to
clean the control, wipe it with a damp cloth.
Before servicing or cleaning unit, switch
power off at service panel and lock the
switch disconnecting means to prevent
power from being switched accidentally.
When the service disconnecting means
cannot be locked, securely fasten a
prominent warning device, such as a
tag, to the service panel.
1.2. Product Overview
The Variable Output Module is used to vary
the intensity of some loads in a livestock
building. It has been designed to accommo-
date various models of fan motors, of heaters
(mats or lamps) and light outputs (dimmable
compact fluorescent lights (CFL), dimmable
cold cathode fluorescent lamps (CCFL) and
incandescent lights).
Depending on the model, the module can
drive one, two or four 1600W (or 2HP)
circuits.
The circuits of a given module can all be con-
trolled the same way by an external control
system or they can be regulated separately
with a combination of control systems.
Below is a list of all possible control sys-
tems that can regulate the circuit(s) of your
module:
- 0-10V output of an environment controller;
- Variable output of an environment controller;
- Time clock or thermostat;
2. MOUNTING INSTRUC-
TIONS
Open the latch and lift the cover. Remove
the black caps located on each of the four
mounting holes. Mount the enclosure on the
wall using four screws. Be sure the electrical
knockouts are at the bottom of the enclosure
in order to prevent water from entering the
controller. Insert the screws in the mounting
holes and tighten. Fasten the four black caps
provided with the controller onto the four
mounting holes.
The enclosure must be mounted in a location
that will allow the cover to be completely
opened right up against the wall.

3. USER INTERFACE
3.1. Override Switch
The override switch allows bypassing all com-
mands given by the main control system to
the output. This switch also has priority over
the potentiometer.
Auto (variable) — This position enables the
potentiometer (see next section).
Off — The output(s) turn off.
On — The output is supplied by full AC current.

3.2. Potentiometer
The potentiometer allows changing the inten-
sity of the outputs manually. It only works
on the circuits whose override switches are
at“Auto (variable)” position.
The potentiometer only works when the
Override Switch is at “Auto (variable)”
position.
Automatic Control — While the knob is at
“AUTO” position, control of the output(s) is
returned to the main control system. If the
module is controlled by a time clock or by a
thermostat, the “AUTO” position will simply
turn the output(s) Off.
Dimmer 1-10 — If the Override switch is at
the “AUTO” position, you can use the poten-
tiometer to change intensity of the output(s)
manually. This will bypass the commands
given by the main control system.

4. WIRING
The circuits of the Variable Output Module
can be controlled by the 0-10V output and/or
variable output of an environment controller
(see below) or they can be controlled by a
time clock or thermostat (see section 4.2).
All wiring must be done by an authorized
electrician and must comply with ap-
plicable codes, laws and regulations.
Be sure power is off before doing any
wiring to avoid electrical shocks and
equipment damage.

In this example,
circuits 1 & 2 are
controlled by the 0-10V
output of an environment
controller and circuits
3-4 are regulated by the
variable output of another
controller. *If you want all
circuits to be controlled the
same way, leave the trig-in

when the controller came out
the factory.
Since power switches 3-4
are not connected to the top
board, it is not possible to
change the intensity of these
loads with the potentiometer.

4.1. Connect Module to
Controller
Some circuits of a given module can be con-
nected to the 0-10V output of an environ-
ment controller while others are regulated by
the variable output of another environment
controller. Figure 7 gives an example of this.
If you prefer giving all circuits the same
function, leave the trig-in & trig-out wires
as they were when the controller came out
the factory.
4.2. Connect Module to Time
Clock or Thermostat
If the module is not controlled by an environ-
ment control, you can connect it to any type
of device that has the capability of controlling
a dry contact relay (time clock, thermostat, or
else). Refer to Figure 8 to connect the module
to a time clock or thermostat.
If you are not using the time
clock input, leave the wire
between terminals 1 & 2 to
make a short.

5.1. Choosing a Motor Curve
If the module is used to drive fan motors,
select the motor curve that corresponds to
the type of motor in use by means of the in-
ternal switches located inside the enclosure
(see Figure 3).
Refer to the Motor Curve table at the back
of the Installation Guide to choose a motor
curve adapted to your fan model.
If an invalid switch combination is se-
lected, the module automatically enables
Light Curve #1.

5.2. Choosing a Light Curve
If the module is used to drive light outputs,
select the proper light curve on the block of
internal switches located inside the enclosure
(see Figure 3). The module has seven (7)
light curves to accommodate most models of
dimmable lamps: (Dimmable Compact Fluo-
rescent Light (CFL), Dimmable Cold Cathode
Fluorescent Lamp (CCFL) and incandescent
lights).
To solve flickering problems with dim-
mable CFL/CCFL lights, decrease the dim-
ming range (i.e decrease curve number).
The minimum light intensity is brighter
when the dimming range is low.
The dimming range increases as the light
curve number increases.

Settings
If the circuit activates CFL/CCFL lights,
leave the lights ON for 24 hours after
first installation before dimming.
1. Select light curve #7 on the block of
internal switches inside the controller (see
Figure 3) and refer to Figure 6 to set the
switches properly.
When the light curve changes, the con-
troller turns OFF the lights and turns
them back ON using the new light curve.
2. Steps 3 and 4 only apply to CFL/CCFL lights
(keep light curve #7 if the circuit is used to
control incandescent lights or heating units).
3. Select the lowest light intensity with the
potentiometer.
• If th e lowes t int ens i t y is too brig h t, increase
the light curve with the internal switches.
• If the lights are flickering, decrease the light
curve with the internal switches.
4. Select another light curve if required and
try to find one that provides a good minimum
intensity and does not make the lights flicker.
If an invalid switch combination is se-
lected, the module automatically enables
Light Curve #1.
5.3. Setting Sunrise/Sunset
If the circuits are used to activate lights
and they are controlled by a time clock, the
module can simulate a sunrise (or sunset)
before each activation (or deactivation) of
the circuits.
Use the sunrise/sunset potentiometer behind
the front panel (see Figure 3) to adjust the
sunrise/sunset delay: Select the “0” posi-
tion if you want to disable this function or
select any other position to set the sunrise/
sunset delay. This delay ranges from 0 to
60 minutes. Each time the relay switches,
the module will gradually increase (sunrise)
or decrease (sunset) the light intensity over
this period of time.
All following conditions must be met for
the sunrise/sunset to work:
•Theinternalswitcheshavealighting
function (see Figure 6).
•Theoverrideswitchisatthe“AUTO”
position.
•Thepotentiometeronthefrontcover
is not at the “AUTO” position.

6. DIMMABLE ENERGY-
EFFICIENT LAMPS
(CFL/CCFL)
6.1. About Dimmable CFL/
CCFL
The module can control the intensity of two
types of energy-efficient lamps:
1. Compact Fluorescent Light (CFL) — This
refers to compact fluorescent light or energy
saving light.
2. Cold Cathode Fluorescent Lamp (CCFL) —
This refers to light sources that are based on
gas discharge principles, where the cathode
of the lamp is not independently heated.
• There are about 35 different electrical
components in a typical dimmable CFL/CCFL
which can cause the bulbs to react differently
one another (some bulbs may extinguish
early; other may flicker before they extinguish
at their low end).
• Dimmable CFL/CCFL may cause interfer-
ence with AM radios, cordless telephones
and remote control devices.
• Dimable CFL should dim to 20% before they
extinguish and CCFL should dim to 5-10%.
• The lifetime of CFL/CCFL are 8 times the
lifetime of incandescent lamps. Many factors
can affect their lifetime:
- Operating voltage;
- Manufacturing defects;
- Exposure to voltage spikes;
- Mechanical shocks;
- Frequency of On/Off cycles;
- Lamp orientation;
- Ambient operating temperature;
- etc.
• The CFL/CCFL produce less light later in
their lives than when they are new: a test
made by the US Department of Energy of
‘Energy Star’ products in 2003–04 has dem-
onstrated that one quarter of tested CFLs no
longer met their rated output after 40% of
their rated service life.
6.2. Recommended Models
The brands and models of dimmable CFLs
listed below have been tested and proven
to work properly with the variable output
module (other models can be used).
1. Overdrive, Sunlight and Greenlite 8W CCFL
2. Retrolite 23W CFL
14
M8000, M4000 & M2000 rev.03
M8000, M4000 & M2000
6.3. Installation Recomman-
dations
A variable output module can only control
one (1) t yp e of dimmab le CFL /CC FL — Using
multiple types, wattages or brands of CFL/
CCFL creates interferences that could cause
the module to work improperly.
Wait for warm up before dimming — The
dimmable CFL/CCFL bulbs may be exposed
to various temperature conditions during stor-
age and transportation. Turn the lamps ON
at 100% for 24 hours after first installation
before dimming.
Make sure the dimmable CFL/CCFL is
screwed tightly in the socket — If the dim-
mable CFL/CCFL bulb is not screwed tightly
in the light fixture, the CFL/CCFL will try to
reset continuously.
Do not toggle the ON/OFF switch repeat-
edly — A dimmable CFL/CCFL has a built-in
protection that forces it to reset in case of
an abnormal situation (air leak, poor contact,
poor burner activation, etc.) A reset can take
about 2 minutes. Consequently, if the CFL/
CCFL does not turn on instantaneously, wait
2 minutes before switching it on again.
