We strongly recommend installing supplementary ventilation as
well as a back-up thermostat on at least one fan stage (refer to
the wiring diagram enclosed with this user's manual to connect
the thermostat).
Although overload and overvoltage protection is provided for the
controller circuits, we recommend installing additional protec-
tion devices in the electrical panel.
The room temperature where the controller is located MUST
ALWAYS REMAIN BETWEEN 32°F AND 104°F (0°C TO
40°C).
To avoid exposing the controller to harmful gases or excessive
humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

Expert-32T rev.03
The Expert-32T is an electronic device used for environmental control in
livestock buildings. It allows the user to maintain a specified target
temperature in two independent rooms by controlling the operation of
ventilation and heating equipment. Each room can operate up to 8
heater stages, 10 on-off fan stages, 2 cooling outputs vent doors, tunnel
curtains and 2 clock outputs. Fan stages can be configured to activate
cooling systems in timer mode. In all, the Expert-32T provides up to 32
relay outputs. In addition, if vent doors are not used, up to 12 PF-6 air
inlet controllers can be connected to the unit.
The main features of the Expert-32T are as follows:
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.
MINIMUM VENTILATION CYCLE
When ventilation is not required for reducing room temperature, the first
and second fan stages can be operated either continuously or intermit-
tently to reduce the level of humidity and supply oxygen to the room.
TEMPERATURE AND MINIMUM VENTILATION CURVES
The controller can be set to automatically change the temperature set
point and the minimum ventilation cycle over a given period 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.
PROBE READINGS RECORDED FOR PAST DAYS
Minimum and maximum readings from temperature and static pressure
probes are recorded for the current day and the previous six days.

WATER MONITORING
A pulse input is provided for monitoring water consumption for the
current days and the previous six days.
ALARM MANAGEMENT
Alarms are provided for high-low temperatures, defective probes and
other system functions. Alarm states are kept in memory until acknowl-
edged even if alarm situation has been rectified.
FOUR INDEPENDENT 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 tempera-
ture and a faster reaction time. Probes can be configured to use zoned
heaters.
STATIC PRESSURE CONTROL
A static pressure input is provided to control static pressure by opening
and closing the vent doors.
CONTROL OF AIR INLET MOVEMENT
If the Expert-32T is used in combination with one or more PF-6 control-
lers, the movement of air inlets can be coordinated with the operation of
the fans using a potentiometer located on the panel drive. This allows
the air inlets to be adjusted correctly, without the influence of uncontrol-
lable factors such as wind or air from adjoining rooms.
TWO PROBE SETS
The probe selection for calculating room temperature can be changed at
some point in the ventilation curve to compensate for changes in airflow
patterns that can distort the room temperature calculation.
PASSWORD PROTECTION
A password feature can be enabled to restrict access to the controller
setup functions.
BACKUP BATTERY
A backup battery allows the unit to keep time in case of a power failure.

OVERLOAD AND OVERVOLTAGE PROTECTION
Resettable fuses are provided at low-voltage inputs and outputs of the
controller to protect its circuitry in the case of an overload or overvolt-
age.
COMPUTER CONTROL
The controller can be connected to a computer, thus making it possible to
centralize the management of information and diversify control strate-
gies.
TEST MODE
A test mode allows you to simulate temperature changes and verify
controller performance.

Room Temperature Display: The display on the top right corner of the
faceplate shows the current room temperature averaged over all se-
lected room temperature probes or the static pressure.
LCD Display: The LCD display on the left gives the current readings and
parameters to be adjusted when you
select a function. The three keys to
the right of the display are used to
edit parameters and step through
the display. 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 ROOM TEMPERATURE display.
Adjusting a Parameter: A parameter can be adjusted when it is flashing
on the LCD display. Use the Edit key to step through the param-
eters displayed. When the required parameter is flashing, use the arrow
keys next to the display to adjust the parameter.
To step to another display screen, it may be necessary to press
the Edit key several times to step through the remaining param-
eters displayed until the up- and down-arrows reappear to the
right of the display.
Output Status LEDs: The LEDs on the right of the control panel give the
status of each output. When the LED is turned on, the output is acti-
vated; when the LED is turned off, the output is deactivated. In the
case of the fan stages, a flashing LED indicates that the activation of the
fan stage is delayed by the opening of the curtain.

ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRI-
CIAN AND MUST COMPLY WITH APPLICABLE CODES,
LAWS AND REGULATIONS. BE SURE POWER IS OFF BEFORE
DOING ANY WIRING TO AVOID ELECTRICAL SHOCKS AND
EQUIPMENT DAMAGE.
INSTALLATION
MOUNTING INSTRUCTIONS
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.
CONNECTIONS
To connect the controller, refer to the wiring diagram enclosed with this
user's manual. Use the electrical knockouts provided at the bottom of
the enclosure. Do not make additional holes in the enclosure, particularly
on the side of the enclosure when using a computer communications
module.
