SMART 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
ALWAYS 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!

SMART THERMOSTAT
FEATURES
The thermostat controller SMART THERMOSTAT is used to adjust the
temperature set point of mechanical thermostats in livestock buildings. It
can also be used as a backup ventilation system when no temperature
controller is detected. When the thermostat controller runs as a stand-
alone unit (i.e. when there is no main temperature controller), the SMART
THERMOSTAT controls the room temperature with 3 fan outputs, 1 heat-
ing output and 1 air intake (tunnel curtain or vent doors).
MAIN FEATURES:
STAND-ALONE BACKUP SYSTEM
The SMART THERMOSTAT starts operating as a stand-alone ventilation
system when one of these conditions occurs:
-There is no communication between the main controller and the ther-
mostat controller for 2 minutes.
-The main temperature controller has transmitted an invalid tempera-
ture set point to the thermostat controller – this happens when there
is a difference of more than 4°F (2.2°C) between two consecutive
set points. This situation causes a set point alarm.
When the thermostat controller operates as a stand-alone unit, it uses the
previous valid set point transmitted by the main temperature controller or
a user-defined set point.
AUTOMATIC THERMOSTAT ADJUSTMENT
The SMART THERMOSTAT reads the set point of the main temperature
controller on a regular basis. This way, if the main controller fails, the
SMART THERMOSTAT continues running using the previous valid set point
provided by the main controller. In other words, there is no need to adjust
mechanical backup thermostat anymore.

FOUR-DIGIT DISPLAY
A four-digit display provides a high level of accuracy, allowing the user to
specify a temperature to within one tenth of a degree (in Fahrenheit or
Celsius units).
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.
TWO INDEPENDENT TEMPERATURE PROBE INPUTS
Up to two 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.
TEMPERATURE CURVE
When the SMART THERMOSTAT is used as a stand-alone unit (i.e. when
there is no main temperature controller), it can automatically change the
temperature set point over a given period of time in accordance with the
user's requirements by specifying a temperature curve with up to six dif-
ferent points.
HIGH/LOW TEMPERATURE ALARM OUTPUT
OVERLOAD AND OVERVOLTAGE PROTECTION
Fuses and other protection devices are installed on the outputs of the con-
troller to protect 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.

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 enclo-
sure 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.
Set the voltage switch to the appropriate voltage.
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.
It may be necessary to install a transformer in order to supply the
appropriate voltage to the heating unit.
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 NO terminal as shown on the wiring diagram. For an alarm of
the second type, use the NC terminal.

TEMPERATURE PROBES
1
Connecting the Probes
The controller is supplied with two temperature probes. Using two probes
allows obtaining a more accurate temperature reading and a faster reac-
tion time. Refer to the wiring diagram to connect the probes.
CAUTION: Probes operate at low voltage and are isolated from the supply.
Be sure that probe cables remain insulated 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.
Switch # 3 activates the additional probe connected to
input # 2. Set the switch #3 to ON if the additional
probe 2 is used.
2
Extending the Probes
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
If a defective probe is detected, the Defective Probe Pilot Light turns
on. The room temperature shown on the display is then the average
temperature measured by the probes in working condition. The control-
ler will operate according to this temperature.
To identify the defective probe:
Set the function to ROOM TEMPERATURE using the function selector
buttons. The room temperature is displayed.
Press the second functions push-button. If the probe
connected to input # 1 and supplied with the control-
ler is not defective, the letters "PR1" are displayed,
alternating with the temperature measured by the
probe and the on/off state of the probe. If the probe is
defective, the letters "PR1" are displayed, alternating
with the state of the probe and the letter "P".
For each additional probe connected to the controller:
Press the second functions push-button once again. If the probe is not
defective, the letters "PR#" (where # is the number of the input to
which the probe is connected) are displayed, alternating with the on/
off state of the probe and the temperature measured by the probe. If
the probe is defective, the letters "PR#" are displayed, alternating
with the on/off state of the probe and the letter "P".

ALARMS
Temperature Alarms
The controller sets off an alarm in the case of a power failure, a fault in the
supply circuit or a high or low temperature. Temperature alarms are de-
fined according to the set point as shown in the diagram below.

Set Point Alarms
The thermostat controller sets off a set point alarm if it detects a change
of more than 4°F (2.2°C) between two consecutive set point values trans-
mitted by the main temperature controller. This type of alarm is likely to
occur if the main controller fails or when a new batch starts.
When this type of alarm is set off, the thermostat controller asks the user
to acknowledge the alarm condition. In the meanwhile, the thermostat
controller operates as a stand-alone unit using the previous valid set point
that was transmitted by the main temperature controller.
