We strongly recommend installing supplementary natural
ventilation, a failure alarm system 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 overvoltage, we
recommend installing an additional protection device on the
supply circuit as well as an external relay on all ON-OFF stages to prolong the life of the controller.
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

SN 5012
FEATURES
The SN 5012 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. Two
stages combining constant-speed fans, heating units or mist sprinklers, as
well as curtains for natural ventilation, can be connected to the controller.
ROOM TEMPERATURE COMPENSATION ON CURTAINS
The main features of the SN 5012 are as follows:
OVERLOAD AND OVERVOLTAGE PROTECTION
THREE-DIGIT DISPLAY
Fuses are installed at the input and outputs of the controller to protect its
circuitry in the case of an overload or overvoltage.
A three-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
The controller compensates the curtain timer settings proportionally to room
temperature. The lower the temperature, the faster the curtains close. The
higher the temperature, the faster the curtains open.
COMPUTER CONTROL
The controller can be connected to a computer, thus making it possible to
centralize the management of information and diversify control strategies.
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 cooling, stage 2 and 3 fans can be
operated either continuously or intermittently to reduce the level of humidity
and supply oxygen to the room.
TEMPERATURE CURVE
The controller can be set to 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 different points.
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 temperature and a faster
reaction time.

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.
n
Set the voltage switch to the appropriate voltage.
n
Use the electrical knockouts provided at the bottom of the enclosure.
Do not make additional holes in the enclosure, particularly on the top
of the enclosure when using a SL 1400 communication board.
n
For the heating stages, 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.

WARNING
8
ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRICIAN
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.
QM 1307.rev.01
TEMPERATURE PROBES
1
Connecting the Probes
The controller is supplied with one room probe connected to input # 1. Three
additional probes can be connected to inputs # 2, 3 and 4 (see wiring diagram
enclosed). If zoned heating is used, Heater A uses probes 1 & 2 and Heater
B uses probes 3 & 4. If staged heating is used, the average temperature from
activated probes # 1, 2, 3 and 4 is used.
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 an input
or a ground.
2
Extending the Probes
Each probe can be extended up to 500 feet (150 meters). To extend a probe:
n
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.
n
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°.

A curve is defined using six points. Each point specifies a day number and
a set point for that day. Once the points of the curve are defined, the curve
must be activated. The controller will change the temperature set point every
hour in a linear fashion between consecutive points of the curve. When the
last point of the curve is reached, the temperature set point for that day is
maintained until the curve is reactivated.
NOTES :
i) All six points of the curve must be specified. If six points are not needed,
repeat the last temperature value for each unnecessary point.
ii) Certain restrictions apply to reduce the risk of errors:
− The highest possible day number is 99.
− Decreasing day numbers are not allowed.
− Increasing temperatures are not allowed.
− The temperature variation cannot exceed 3°F (1.6°C) per day.

Adjusting the Opening and Closing Temperatures
The opening and closing temperatures are the temperature values at which
the curtains open or close. The hysteresis is fixed at 0.3oF and determines
when the curtains stop operating. The opening and closing temperatures can
be adjusted from 0.5°F to 20.0°F (0.3°C to 11.1°C) above and below the set
point respectively.

CURTAIN OPERATING TIME COMPENSATION
When curtain compensation is turned on, the controller uses the current
room temperature to gradually adjust the timer settings for opening and
closing the curtains as the temperature departs from the set point. The
higher the room temperature, the faster the curtains open. Likewise, the
lower the room temperature, the faster the curtains close. To use this feature, set internal switch # 8 to ON.
Temperature Rises:
When the room temperature rises above the curtain opening temperature,
the controller increases the on time and decreases the off time settings for
the opening cycle such that the total cycle time remains constant.
When the off time is below 10 seconds, the curtains begin to open continuously.

The difference between the current temperature and the opening temperature of the curtains is 0.3 degrees Fahrenheit. According to Table 1 below,
this gives a compensation factor of one. Therefore, the on time for opening
the curtains maintains its current value.

In Example 2, the difference between the current temperature and the opening temperature has risen to 2.8°F. According to Table 1 above, this gives a

Temperature Falls:
When the room temperature falls below the curtain closing temperature,
the controller increases the on time and decreases the off time settings for
the closing cycle such that the total cycle time remains constant.
When the off time is below 10 seconds, the curtains begin to close continuously. The controller uses the compensation factors given in Table 1.

Adjusting the Stage 2 or 3 Starting Temperature
The timer is used to operate the mist units when the starting temperature of
the stage has been reached. In the case of cooling fans, the timer is used
to provide minimum ventilation when the temperature drops 1.5°F below the
starting temperature. The timer operates as shown below:
ON TIME
The starting temperature is the temperature at which the fans start running
continuously or the temperature at which the mist units start running in timer
mode (see the Configurations section). The hysteresis is fixed at 1.5oF. It
determines when the fans stop running continuously and start operating in
timer mode or when the mist units stop running.

ZONED HEATERS
To configure your system for zoned heaters, set dipswitch #3, #4 and # 5 to
ON. Since the two heater outputs function independently, different probes
are assigned to each output: Probes 1 & 2 are assigned to Heater A and
Probes 3 & 4 are assigned to Heater B. Individual probes can be turned on
or off using the push-button functions contained in the ROOM TEMPERATURE function (see section on Temperature Settings).
If the room temperature falls:
- at 73oF:

Note that the heaters can become active only if the average temperature
from all activated probes is below the set point. If this isn't the case, the
heaters will not turn on even if individual probe temperatures are below the
set point (this condition applies only if both off temperatures are below the
set point).
The figure below explains the operation of zoned heaters.
