1. INTRODUCTION
1.1. Precautions
WARNING: Read and save these
instructions!
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.
We strongly recommend installing supplemen-
tary natural ventilation as well as a back-up
thermostat on at least one cooling stage (refer
to the wiring diagram enclosed with this user’s
manual to connect the thermostat).
Although fuses at the input and outputs of
the controller protect its circuits in case of
an overload or over-voltage, we recommend
installing an additional protection device on
the controller’s supply circuit.
The room temperature where the controller
is located must always remain between 32°F
and 104°F (0°C to 40°C). Indoor use only!
To avoid exposing the controller 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 protec-
tion provided by the equipment may be
impaired.
Do not spray water on the controller! 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 ser-
vice disconnecting means cannot be
locked, securely fasten a prominent
warning device, such as a tag, to the
service panel.
1.2. Symbols of the Manual
Warning. Read the following text
carefully; it contains important
information which, if ignored, may
cause the controller to operate
improperly.

1.3. Features
The EXPERT 2V2SA is an electronic device
used for environmental control in livestock
buildings. It allows the user to maintain a
specified target temperature by controlling
the operation of ventilation and heating
equipment. The EXPERT 2V2SA can control
the following outputs:
- 2 variable fan outputs
- on/off outputs (heaters, misters or fans)
- 1 air inlet output
- 1 0-10V output (heaters, heat mats, chim-
ney or fans)
Main Features :
LCD Display — An LCD display provides an
efficient interface for displaying, monitoring
and adjusting parameter values.
Pilot Lights — Pilot lights indicating the state
of outputs allow the user to monitor the
operation of the system without having to
enter the building.
Removable Connectors — Input connectors
can be removed from the main board to
simplify wiring.
Minimum Ventilation Cycle — When ven-
tilation is not required for reducing room
temperature, the first and second fan stages
can be operated either continuously or inter-
mittently to reduce the level of humidity and
supply oxygen to the room.
Temperature & Min. Ventilation Curves —
The controller can be set to automatically
change the temperature set point and the
minimum ventilation cycle over a given pe-
riod of time, in accordance with the user's
requirements, by specifying a temperature
curve and a minimum ventilation cycle curve
with up to ten different points each.
Choice of Ten Motor Types — The variation
in motor speed resulting from a change in
voltage will depend on the make and capac-
ity of the motor. In order to achieve a high
degree of compatibility between controller
and motor, the user can choose from among
ten different motor types, thus ensuring that
the correct voltage is supplied.
Zoned Heaters
Probe Readings Recorded For Past Days —
Minimum and maximum readings from tem-
perature probes, static pressure sensors and
humidity sensor are recorded for the current
day and the previous six days.
Water Monitoring — A pulse input is provided
for monitoring water consumption for the cur-
rent days and the previous six days.
Heater Run Time Monitoring — Heater run
times are kept in memory for the current day
and for the previous six days.
Alarm Management — Alarms are provided
for high-low temperatures, defective probes
and other system functions.
Four Temperature Probe Inputs — Up to four
temperature probes can be connected to the
controller in order to obtain a more accurate
reading of the average room temperature and
a faster reaction time.
Outside Temperature Compensation — Fan
stages are automatically adjusted according
to the outside temperature. This ensures a
better stability in the room temperature.
0-10V Output — One 0-10V output can be
activated to control supplementary ventila-
tion or heating stages or to control chimney
dampers.

EXPERT 2V2SA, rev. 10
EXPERT 2V2SA

Humidity Compensation — The control offers
many ways to compensate for high or low
humidity levels.
Static Pressure Control — A static pressure
input is provided to control the static pressure
level by opening and closing the air inlets.
When the pressure level is too high, the inlet
opens to compensate. When the pressure
level is too low, the air inlet closes.
Control of Air Inlet Movement — The move-
ment of air inlet can be coordinated with the
operation of the fans. This allows the air inlet
to be adjusted correctly, without the influ-
ence of uncontrollable factors such as wind
or air from adjoining rooms.
Password Protection — A password allows
to restrict access to the controller's setup
functions.
Backup Battery — A backup battery allows
the unit to keep time in case of a power
failure.
Overload And Overvoltage Protection — Re-
settable fuses are provided at low-voltage
inputs and outputs of the controller to pro-
tect its circuitry in the case of an overload
or overvoltage.
Computer Control — The controller can be
connected to a computer, thus making it
possible to centralize the management of
information and diversify control strategies.
Test Mode — A test mode allows you to
simulate temperature changes and verify
controller's performance.

2. MOUNTING INSTRUC-
TIONS
2.1. Installing the Controller on
the Wall
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.
2.2. Connections
Refer to the wiring diagram enclosed with this
user’s manual to connect the controller. Drill
holes at the bottom of the enclosure to pass
the wires and install watertight connectors to
prevent water from entering in the enclosure.
Do not make any holes at the side and top
of the enclosure.
All wiring must be done by an au-
thorized electrician and must comply
with applicable codes, laws and
regulations. Make sure power is off
before doing any wiring to avoid
electrical shocks and equipment
damage.
Note that the input terminal blocks
can be removed from the electronic
board. This makes it easier to make
the connections.
2.2.1. Sensor Inputs
Sensors operate at low voltage and are isolated
from the supply. Make sure that sensor cables
remain isolated from all high voltage sources.
In particular, do not route the sensor cables
through the same electrical knockout as other
cables. Do not connect the shield from the
sensor cable to a terminal or a ground.
Extending a sensor: Each sensor can be ex-
tended up to 500 feet (150 meters).
To extend a sensor: Use a shielded cable
of outside diameter between 0.245 and
0.260 in (6.22 and 6.60 mm) (the cable
dimensions should not be under 18 AWG) to
ensure the cable entry is liquid tight. Do not
ground the shielding.
It is preferable to solder the cable joint to
ensure a proper contact between the two
cables.
Do not run sensor cables next to other
power cables. When crossing over
other cables, cross at 90°.
Defective sensors:
An alarm is gener-
ated when a defective
sensor is detected.
To identify the defective probe, select the
PROBE TEMPERATURE or OUTSIDE TEM-
PERATURE menu. Probe readings are then
displayed. Dashes are displayed instead of a
reading when the probe is defective. In the
case of room temperature probes, the control-
ler will operate according to the temperature
of the remaining probes.
2.2.2. Alarm Connection
There are two types of alarms on the market.
One type activates when current is cut off at
its input, whereas the other activates when
current is supplied at its input. For an alarm of
the first type, use the NC terminal as shown on
the wiring diagram. For an alarm of the second
type, use the NO terminal.

3. USER INTERFACE
3.1. Location of the Controls
Digital LED Display — The red LED dis-
play at the top can show various pieces
of information such as the average room
temperature, static pressure level, inlet
position, etc.
LCD Display — The LCD screen shows
the current readings and parameters to
be adjusted when you select a function.
The three keys next to the display are
used to edit parameters and scroll down
the menus. When the parameters for a
given function cannot all be presented at
once on the display, arrows are displayed
on the right hand side to indicate that
additional parameters can be displayed
using the arrow keys. After 15 minutes of
inactivity, the display returns to the current
temperature display.
Adjustment and Navigation Keys — The
arrow keys on top are used to scroll down
the menus when the parameters cannot
be presented all at once. These keys are
also used to modify a parameter in the
editing mode.
Output Status LEDs — The LEDs located
at the left side of the control panel give the
status of each output. When an output
LED is on, the output is activated; when it
is off, the output is deactivated.
3.2. Parameter Adjustment
Select a parameter you want to adjust and
then press the MODIFY push-button to enter
the editing mode. The parameter's value will
start flashing on screen which means it can
be modified. Use the up and down-arrow
keys located next to the display to modify the
parameter's value. Finally, press the MODIFY

(The parameter adjustment process is explained
in section 3.2 on page 8).
4.3. Selecting Type of Motor
The relationship between the voltage supplied
to a motor and its operating speed is described
by a motor curve. This curve varies with the
make and capacity of the motor. The various
motors available in the industry have been
divided into ten categories and the controller
has been programmed with a different motor
curve for each of these categories. To ensure
that the controller supplies the correct volt-
ages, an appropriate curve must be selected
for Stage 1 and Stage 2, according to the type
of fan motors used.
1. From the main menu, select: STAGE 1 or
STAGE 2.

15. MEMORY CARD
The memory card is used to create a backup
copy of your controller’s configuration. The
card is also useful to transfer the configura-
tion of one controller to another controller of
the same type.
The switch on the card is used to lock or to
unlock the card ( = locked, = unlocked).
Turn off power each time you open
the controller’s enclosure. This pre-
vents accidental exposure to areas
of high voltage.

The clean mode is used to interrupt regular
operations of the controller when the room
is empty. When this mode is enabled, the
controller only provides a minimum level of
heat and ventilation (optional). If minimum
ventilation is used in the clean mode, the
air inlet will open to its respective minimum
ventilation position; otherwise it will remain
closed.
Cleaning the room: A soaking output can be
used to clean up the room. If this output is
enabled, it will automatically start running
according to a user-defined timer at clean
mode startup. Refer to chapter 8 on page
32 to get further information about the
soaking output.
Clean mode set point: During the clean mode,
the fans that are used to provide minimum
ventilation and the heaters operate accord-
ing to the clean mode set point: the heaters
turn on when the room temperature is lower
than the clean mode set point and fans turn
on when temperature is higher than this set
point.

4.6. Test Mode
A test mode allows you to simulate tem-
perature changes and verify controller perfor-
mance. In test mode, the room temperature
probe inputs are turned off, allowing the user
to change the temperature used by the con-
troller to operate the stages. The controller
operates as before using the new temperature
settings.
The test mode is used to simulate tempera-
ture changes in order to verify the controller’s
performance. The temperature probe inputs
are turned off while the test is on and the
test automatically ends after 15 minutes of
inactivity.

5. TEMPERATURE SET
POINTS
The set point is a target temperature in
the room. The activation of most outputs
of the controller is based on this reference
temperature.
Note that the set point can only be
modified while the set point curve
is disabled. Refer to the following
section to disable the curve.
5.1. Set Point Settings
1. From the main menu, select: SET POINT
/ CURVE.
2. Set the following parameters:
(The parameter adjustment process is explained
in section 3.2 on page 8).
Setp 75.0°F
ClnSetp 45.0°F
Night Setpoint
75.0°F
Setp — Set the temperature set point
that is used during the day (this set point
is used all day long if the night set point
is not enabled). It ranges from -40.0°F to
100°F (-40.0°C to 37.8°C) *This parameter
can only be modied while the set point curve is
inactive (sec. 5.2.)
Clean mode set point — Select what is
the target room temperature while the
controller operates in clean mode.
Night Set Point — A different temperature
set point can be used at night. The night
set point can be used to lower the target
room temperature for instance. This set
point is relative to the day set point, which
means that it is automatically adjusted
when the day set point changes. Set the
night set point to the desired value. *This
parameter is accessible if the night set point is
enabled in the User Setup Menu.
5.2. Set Point Curve
A curve is made of 10 steps. Each step speci-
fies a day number and a temperature set point
for that day. Once the curve is activated, the
controller changes the set point every hour in
a linear fashion between consecutive steps
of the curve. When the last step is reached,
the controller keeps using the temperature
set point associated to that day.

Point
When the average room temperature ex-
ceeds the high temperature alarm setting, a
high temperature alarm is generated. When
the average room temperature drops below
the low temperature alarm setting, a low
temperature alarm is generated. Although
these settings are entered by the user as
absolute values, they are defined relative to
the current set point and are automatically
adjusted by the controller when the set point
changes. This means, for example, that when
the controller switches to the nighttime set
point, the high and low temperature alarms
are readjusted using the same offset from the
daytime set point.
The situation is slightly different when the out-
side temperature is greater than the set point.
In this case, the high alarm set point is replaced
by the outside temperature as the reference
point. Another parameter, called the critical
temperature, is defined to continue monitoring
the indoor temperature for high temperatures.
When the indoor temperature reaches the criti-
cal high temperature (defined as an absolute
value), an alarm is set off.
12.1.2.2. Water Alarms
• Water Spill Alarms:
A water spill alarm sets off when the water
consumption exceeds a certain limit. This limit
can be adjusted from 0 to 1,000 gallons or
liters per 15 minutes. The alarm is activated if
a greater amount of water is detected within
the 15 minute interval. A separate water spill
limit can also be defined for day and night.
• Water Consumption Alarms:
When the percent difference in water con-
sumption between the last 24-hour period
and the previous 24-hour period is greater
than a given maximum value, an alarm is
set off.
Last 24h

Water Consumption
The high and low water consumption alarm
limits are defined as follows:
• Ca se #1: If more water has been consumed
in the last 24 hours than in the 24 hours
that precede, the controller will determine
how much more water has been consumed
and will convert this value in percent. If the
surplus (in %) is higher than the “High Alarm”
limit, the controller will set off an alarm.
Last 24h - Previous 24h x 100 > Hi Alarm
Previous 24h
• Case #2: If less water has been consumed
in the last 24 hours than in the 24 hours that
precede, the controller will determine how
much less water has been consumed and will
convert this value in percent. If the deficit (in
%) is higher than the “Low Alarm” limit, the
controller will set off an alarm.

12. MONITORING
FUNCTIONS
12.1. Alarms
The alarm output is activated when an
abnormal situation occurs. Each triggered
alarm is logged in a history menu and must
be acknowledged by the user. The alarm
conditions are as follows:
- Defective temperature probe;
- Defective outdoor probe;
- Defective humidity probe;
- Defective static pressure probe;
- Hi/Low/Critical temperature;
- Clean mode low temperature;
- Water spill alarm;
- Hi/Low Water usage.
When an alarm is active, its respec-
tive pilot light turn on; when an alarm
is no longer active but has not been
acknowledged by the user, its pilot
light flashes. Refer to the following
section of this manual to acknowl-
edge the alarms.
Another alarm situation occurs when power
to controller fails. In this case, the alarm relay
is activated.

6. COOLING
6.1. Minimum Ventilation
6.1.1. Principle of Operation
Definition: Minimum ventilation cycles are
activated when the room temperature is
lower than the set point. Running the fans
even though ventilation is not required for
reducing the room temperature is useful to
reduce humidity levels and supply oxygen
to the room. It also prevents the fans from
freezing in winter.
Minimum Ventilation Timer: During the "Time
On", the fans of stage 1 run at their minimum
speed and the status LED associated with
stage 1 is on; during the "Time Off", the fans
return to a stop and the status LED is off.
Note that the minimum speed of stage 1 can
automatically be adjusted with time by using
a curve (see section 6.1.4 on page 22).

Hints
The controller supplies maximum
voltage to the variable-speed fans
for 2 seconds at each start-up.
To run the fans continuously at
minimum speed, set the Time Off
to zero and Time On to any value
other than zero.
To stop the fans, set the Time On
to zero and Time Off to any value.
Refer to section 6.2.3 to set the
minimum speed of stage 1.
