We strongly recommend installing supplementary natural
ventilation, a failure alarm system as well as a back-up ther-
mostaton atleast onecoolingstage (refertothe wiringdiagram
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

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.
Twostagesofvariablespeedcoolingfans andtwo stagesofeitherconstant-
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
Celsiusunits).
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
Thecontrollercanbe set toautomaticallychangethe temperature setpoint
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
Thevariationinmotor speed resultingfroma change involtagewilldepend
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.
FEATURES

ST 5220
QM1336.rev.01
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
followingeachstart-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.

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
electricalknockoutasothercables. Donotconnecttheshieldfromtheprobe
cable to an input or a ground.

nUseashieldedcableofoutsidediameterbetween0.245and0.260in
(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.
nIt is preferable to solder the cable joint to ensure a proper contact
betweenthetwocables.
CAUTION: Do not run probe cables next to other power cables. When
crossing over other cables, cross at 90°.
