QM 1328.rev.02
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.

ST 50210
FEATURES
The ST 50210 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. Ten
stages of constant-speed cooling fans can be connected to the controller,
as well as two stages of either constant-speed fans or heating units. In
addition, the last cooling stage can be configured as a mist cooling stage.
The main features of the ST 50210 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 humidity and
supply oxygen to the room.
reaction time.
ZONED OR STAGED HEATERS
OVERLOAD AND OVERVOLTAGE PROTECTION
Fuses are installed at the input and 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
If the ST 50210 is used in combination with a SB 2000 controller, the movement 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. When tunnel
ventilation is being used, the SB 2000 closes the air inlets.
HIGH/LOW TEMPERATURE ALARM OUTPUT
MINIMUM VENTILATION COMPENSATION CURVE
An outside probe can be connected to the controller to adjust the minimum
ventilation cycle as a function of outside temperature.
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

TEMPERATURE PROBES
1
Connecting the Probes
The controller is supplied with one indoor temperature probe. Three additional
indoor probes can be connected to obtain more accurate readings or to
control different parts of the building. In addition, an outdoor probe can be
connected if the compensation function on the minimum ventilation cycle is
needed (see the chapter on ventilation).
ð
Use terminals # 2, 3 and 4 to connect additional indoor probes and
terminal # 5 to connect the outdoor probe, as shown on the wiring diagram
enclosed.
CAUTION: 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 an input
or a ground.

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.

When the room temperature is below the set point, the Stage 1 fans operate
according to the minimum ventilation cycle. Running the fans even though
ventilation is not required for a cooling purpose is useful to reduce humidity
levels and supply oxygen to the room. It also prevents the fans from freezing

Option 2: Without Ramping
This option is activated by setting internal switch # 6 to OFF. When the
temperature is less than the set point + timer temp. range, Stage 1 fans run
according to the minimum cycle (see above). When the room temperature
reaches point A, stage 1 fans run continuously with no transition.
When the temperature decreases 1.5oF below point A, Stage 1 fans start
operating according to the minimum ventilation cycle.
* When Time Off becomes less than 15 seconds, it is fixed at 15 seconds until
the temperature has reached the set point + timer temp. range. At that point,
the stage 1 fans operate continuously.

MINIMUM VENTILATION COMPENSATION
The ST 50210 has the capability of automatically adjusting the running time
of the minimum ventilation fans as a function of outside temperature. As
the weather gets colder, the on time is decreased gradually to compensate
for the change. This can help reduce costs by reducing the ventilation when
it is not required. A curve is used to calculate the required compensation
as a percentage of current on time (see following page). Only the running
time is adjusted; the total cycle time remains unchanged. Note that internal
switch # 7 must be set to ON for this feature to work.

To configure your system for zoned heaters, set dipswitch # 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).
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).
Ventilation problems can result if heating levels in the two zones are very
different. This is because the fans are operated according to the average
temperature from all zones. Suppose the animals are young and confined
