PRECAUTIONS
EEE
—
«== = ——
We strongly recommend installing supplementary natural
ventilation, a failure alarm system as well as a back-up ther-
mostat on at least one cooling stage (refer to the wiring diagram
enclosed with this user's manual to connect the thermostat).
Although fuses on the 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 exces-
sive humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER
FOR CUSTOMER USE
Enter below the serial number located on
the side of the controller and retain this
information for future reference.

FEATURES
The ST 5220 is an electronic device used for environmental control in
livestock buildings. It allows the user to maintain a specified target tem-
perature by controlling the operation of ventilation and heating equipment.
Two stages of variable speed cooling fans and two stages of either constant-
speed cooling fans or heaters can be connected to the controller. In addi-
tion, the last cooling stage can be configured as a mist cooling stage.
The main features of the ST 5220 are as follows:
THREE-DIGIT DISPLAY
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
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, the first stage fans can be
operated either continuously or intermittently to reduce the level of humid-
ity and supply oxygen to the room.
TEMPERATURE AND MINIMUM VENTILATION SPEED CURVES
The controller can be set to automatically change the temperature set point
and the minimum ventilation speed over a given period of time in accor-
dance with the user's requirements by specifying a temperature curve and
a minimum ventilation speed curve with up to six different points each.
CHOICE OF FIVE MOTOR CURVES
The variation in motor speed resulting from a change in voltage will depend
on the make and capacity of the motor. In order to achieve a high degree
of compatibility between controller and motor, the user can choose from
among five different motor curves, thus ensuring that the correct voltage is
supplied.
4 QM1336.rev.01
ST 5220
FULL-SPEED FAN START-UP
In order to overcome the inertia of the ventilation system components and
de-ice the fan blades in cold weather conditions, the controller supplies
maximum voltage to the variable speed fans for 2 seconds immediately
following each start-up.
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.
OVERLOAD AND OVERVOLTAGE PROTECTION
Fuses and other protection devices are installed on the outputs of the
controller 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.
CONTROL OF AIR INLET MOVEMENT USING THE SB 2000
If the ST 5220 is used in combination with a SB 2000 controller, the move-
ment of the air inlets can be coordinated with the operation of the fans
using a potentiometer located on the curtain machine or baffle actuator.
This allows the air inlets to be adjusted correctly, without the influence of
uncontrollable factors such as wind or air from adjoining rooms.

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 preventwater fromentering 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
Toconnect the controller, refer to the wiring diagram enclosed with this user's
manual.
MM Setthe voltage switch to the appropriate voltage.
ME Usetheelectrical knockouts provided atthe bottom ofthe enclosure. Do
not make additional holes in the enclosure, particularly on the top ofthe
enclosure when using a SL 1400 communication board.
Ш If metallic cable holders are used to secure cables entering the
enclosure, use the ground plate provided with the controller. Connect
the ground wire to the ground stud on the plate.
EM Forthe 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 currentis cut off atits 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 alarmofthe second type,
use the NC terminal.
ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRI-
Л\ CIAN AND MUST COMPLY WITH APPLICABLE CODES, LAWS
AND REGULATIONS. BE SURE POWER IS OFF BEFORE DO-
ING ANY WIRING TO AVOID ELECTRICAL SHOCKS AND EQUIP-
MENT DAMAGE.

MOTOR TYPES
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 ofthe motor. The various motors available in the industry have been
divided into five 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 voltages, an appropriate curve must be
selected for Stage 1 according to the type of fan motors used (see table on
following page).
En Selecting a Motor Type for Stage 1

TEMPERATURE PROBES
EB Connecting the Probes
The controlleris supplied with one room probe connected toinput#1. Three
additional probes can be connected toinputs#2, 3and 4 (see wiring diagram
enclosed).
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.
El Extending the Probes
Each probe can be extended up to 500 feet (150 meters). To extenda probe:
B Useashielded 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.
M 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°.

MINIMUM VENTILATION SPEED CURVE
The user can define a minimum ventilation speed curve to adjust the Stage
1 minimum speed automatically over a given time period. Each curve is
defined by six points. Each point specifies a day number and a fan speed
for that day. Once the points are defined, the minimum speed curve must
be activated. When the minimum speed curve is activated, the controller
adjusts the Stage 1 minimum speed every hour in a linear fashion be-
tween two consecutive points.
When the last point of the curve is reached, the curve is deactivated. The
controller maintains the minimum speed specified for this point until the
curve is reactivated or until a new single minimum speed is specified using
the first method.

NOTE:
If the room temperature falls below the threshold value given in table 1,
the fans will begin to run at the minimum speed specified for the first
point of the curve and will continue to do so as long as the room
temperature remains below the set point. When the room temperature
rises above the set point, the fans will return to the current minimum speed,
calculated according to the minimum speed curve.

Interaction Between the Temperature Curve and the Mini-
mum Speed Curve
* The minimum speed curve can be activated only if the tempera-
ture curve is already activated
* All points of the minimum speed curve other than the first one are
automatically given day numbers identical to those specified for the
temperature curve. Only the first point of the minimum speed curve
has an adjustable day number. This day number must be greater or
equal to the day number specified for the first point of the tempera-
ture curve and less than the day number specified for the second
point of the temperature curve (see example 1).

* When the minimum speed curve is activated, it will effectively be
operating (i.e. the controller will begin to adjust the minimum speed
according to the specified points of the curve) only when the current
day number of the temperature curve reaches the first day number of
the minimum speed curve.
EXAMPLE 2

If you activated the temperature curve yesterday, the current day
number of the temperature curve is d6. Therefore, if you activate the
minimum speed curve today, it will effectively be in operation in 4
days, when the current day number of the temperature curve reaches
d10. In the meantime, the fans will run at the specified single
minimum speed (see example 2).
* If you activated the temperature curve six days ago, the current day
number of the temperature curve is d11. Therefore, if you activate
the minimum speed curve today, it will effectively be in operation the
moment you activate it. In this case, the current minimum speed will
be a value between 10% and 20%.
