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 protection
devices in the electrical panel.
The room temperature where the controller is located MUST AL-
WAYS REMAIN BETWEEN 32°F AND 104°F (0°C TO 40°C).
To avoid exposing the controller to harmful gases or excessive hu-
midity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

The Expert-50 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 equip-
ment. Eight heater stages, 15 fan stages, tunnel curtains and 4 clock
outputs can be connected to the controller. Fan stages can be configured
to activate cooling systems in timer mode. In all, the Expert-50 provides
up to 32 relay outputs and 2 variable-speed outputs. In addition, up to 12
air inlet modules can be connected to the Expert-50.
The main features of the Expert-50 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, vari-
able-speed outputs can be operated either continuously or intermittently
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 fan speed over a given period of time
in accordance with the user's requirements by specifying a temperature
curve and a minimum ventilation speed curve with ten different points
each.
PROBE READINGS RECORDED FOR PAST DAYS
Minimum and maximum readings from temperature and humidity 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.

HUMIDITY COMPENSATION
The minimum ventilation speed can be adjusted automatically as a
function of relative humidity. Cooling units can be shut off when humid-
ity levels are too high. In addition, heater outputs can be activated when
humidity levels are too high.
SIX INDEPENDENT TEMPERATURE PROBE INPUTS
Up to six 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. Probes can be configured to use zoned heaters.
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
strategies.
TEST MODE
A test mode allows you to simulate temperature changes and verify
controller performance, as well as manually activate each output sequen-
tially.
CONTROL OF AIR INLET MOVEMENT
If the Expert-50 is used in combination with one or more air inlet mod-
ules, 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 uncontrollable
factors such as wind or air from adjoining rooms.

Probes operate at low voltage and are isolated from the supply.
Be sure that probe cables remain isolated from all high voltage
sources. In particular, do not route the probe cables through the
same electrical knockout as other cables. Do not connect the
shield from the probe cable to a terminal or a ground.
Extending a probe: Each probe can be extended up to 500 feet (150
meters). To extend a probe:
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.
CAUTION: Do not run probe cables next to other power cables. When
crossing over other cables, cross at 90°.
Defective probes: An alarm is generated when a defective probe is
detected. To identify the defective probe, select the functions, PROBE
TEMPERATURES and RELATIVE HUMIDITY. Dashes are displayed
instead of a reading when the probe is defective. In the case of room
temperature probes, the controller will operate according to the tem-
perature of the remaining probes.
2. RELAY PANELS
Use a shielded cable with two twisted pairs. Connect the shielding to
the SH terminal. Use one pair for terminals 1 and 4 and the other pair
for terminals 2 and 3.
