We strongly recommend installing supplementary ventilation as
well as a backup thermostat on at least one fan stage (refer to the
wiring diagram enclosed with this user's manual to connect the
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
humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

TC6-2V1SA.rev.05
The TC6-2V1SA 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 of variable fans and one stage of either heaters,
mist or ON/OFF fans can be controlled. The main features of the
TC6-2V1SA are as follows:
LCD DISPLAY
An LCD display provides an efficient interface for displaying, monitoring
and adjusting parameter values.
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.
REMOVABLE CONNECTORS
The inputs' connection is now made easier by removing the connectors
from the main board.
MINIMUM VENTILATION CYCLE
When ventilation is not required for reducing room temperature, the first
and second fan stages can be operated either continuously or intermit-
tently to reduce the level of humidity and supply oxygen to the room.
TEMPERATURE AND MINIMUM VENTILATION CURVES
The controller can be set to automatically change the temperature set
point and the minimum ventilation cycle over a given period of time, in
accordance with the user's requirements, by specifying a temperature curve
and a minimum ventilation cycle curve with up to ten different points each.
CHOICE OF TEN MOTOR TYPES
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 ten different motor types, thus ensuring that the correct voltage is
supplied.

TC6-2V1SA
PROBE READINGS RECORDED FOR PAST DAYS
Minimum and maximum readings from temperature probes, static pressure
sensors and humidity sensor are recorded for the current day and the
previous six days.
WATER MONITORING
A pulse input is provided for monitoring water consumption for the current
days and the previous six days.
HEATER RUN TIME MONITORING
Heater run times are kept in memory for the current day and for the previous
6 days.
ALARM MANAGEMENT
Alarms are provided for high-low temperatures, defective probes and other
system functions.
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.
OUTSIDE TEMPERATURE COMPENSATION
Fan stages are automatically adjusted according to the outside tempera-
ture. It ensures a better stability in the room temperature.
0-10V OUTPUTS
Two 0-10V outputs can be activated to control supplementary ventilation
or heating stages. The 0-10V output can also control chimney dampers.
HUMIDITY COMPENSATION
The minimum speed of stage 1 fans can automatically be adjusted accord-
ing to the humidity level in the barn. Cooling units can also be shut off
when humidity levels are too high.
STATIC PRESSURE CONTROL
A static pressure input is provided to control the static pressure level by
opening and closing the air inlets. When the pressure level is too high, the
inlet opens to compensate. When the pressure level is too low, the air inlet
closes.

TC6-2V1SA.rev.05
TC6-2V1SA
CONTROL OF AIR INLET MOVEMENT
The movement of air inlets can be coordinated with the operation of the
fans using a potentiometer located on the panel drive. This allows the air
inlets to be adjusted correctly, without the influence of uncontrollable
factors such as wind or air from adjoining rooms.
PASSWORD PROTECTION
A password allows restricting access to the controller's setup functions.
BACKUP BATTERY
A backup battery allows the unit to keep time in case of a power failure.
OVERLOAD AND OVERVOLTAGE PROTECTION
Resettable fuses are provided at low-voltage inputs and outputs of the
controller to protect its circuitry in the case of an overload or overvoltage.

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. 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.
Note that the input connectors are now removable. This makes
it easier to connect the different elements to the terminals.
1. PROBES
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 a terminal or a ground.
Extending a probe: 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.
ALL WIRING MUST BE DONE BY AN AUTHORIZED ELECTRI-
CIAN 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.

2. ALARM
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 NC terminal as shown on the wiring
diagram. For an alarm of the second type,
use the NO terminal.
1: 74.2 2:-----
3: 72.3 4:73.0
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:
An alarm is generated when a defective probe
is detected. To identify the defective probe,
select the PROBE TEMPERATURE or OUT-
SIDE TEMPERATURE function. Dashes are displayed instead of a reading
when the probe is defective. In the case of room temperature probes, the
controller will operate according to the temperature of the remaining probes.

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 of the motor. The various motors available in the industry have
been divided into ten 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 separately for stages 1 and 2 variable fans, according to the type
of fan motors in use.
