PRECAUTIONS
We strongly recommend installing supplementary natural ventilation 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 controller's supply circuit.
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
FOR CUSTOMER USE
Enter the serial number located on the
side of the controller below for future

TC5-2N6FA
FEATURES
The TC5-2N6FA 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 speed fans, two stages of constant speed
fans, as well as curtains, foggers and heaters can be connected to the
controller.
The main features of the TC5-2N6FA are as follows:
FIVE-DIGIT DISPLAY
A five-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.
RAMPING FUNCTIONS
Ramping functions provide an automatic adjustment of the set point and
minimum ventilation fan speed over a given period of time.
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.
HIGH/LOW TEMPERATURE ALARM OUTPUT
HUMIDITY COMPENSATION
The stage 1 minimum speed can be adjusted automatically as a function
of relative humidity. As humidity increases, the minimum speed of stage
1 fans increases proportionally to compensate for the change.
4
TC5-2N6FA rev.01
TC5-2N6FA
ZONED OR CASCADING HEATERS
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 during the 2 seconds immediately following each start-up.
DE-ICING CYCLE
A de-icing cycle is provided for de-icing stage 2 variable-speed fans in
cold weather conditions.
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 ON CURTAIN SPEED
Curtain opening and closing times can be decreased as a function of outside temperature.
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.
MEMORY CARD:
A memory card is used to create a copy of your controller's parameters.
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 TC5-2N6FA is used in combination with a PF-6 controller, the
movement of the 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.
TEST MODE
A test mode allows you to simulate temperature changes and verify controller performance.

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 for stage 1
and stage 2 according to the type of fan motors used.
Selecting a Motor Type for Stage 1 and Stage 2
1
Refer to the list of motors enclosed with this user's to choose the
proper motor type.
•

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.
•
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°.

CHANGING THE PARAMETER SETTINGS
Using the Display
Flashing Values:
The display will flash in certain cases
and not in others. The flashing indicates that the value shown can be
adjusted. A value that is not flashing
cannot be adjusted.
Relative and Absolute Values:
Some parameter adjustments are displayed both as a relative value
and an absolute temperature. This applies all heating and cooling
differentials, the mist differential and the heater offset. The parameter is first displayed as a relative value. The corresponding
absolute temperature is displayed after six seconds if no action is
taken by the user. The absolute value is the temperature at which
the stage turns on (except in the case of the heater and mist
offsets where the value displayed is the temperature at which
the stage turns off). If the user turns the adjustment knob, the
relative value reappears. For example, when the user turns the
selection knob to a differential position, i.e. DIFFERENTIALS 3-4,
the sequence is as follows:
(i) The current differential for stage 3 flashes on the display,
alternating with "3 dIF".
(ii) If, after about 10 seconds, no action is taken by the user, the
absolute temperature value is displayed, alternating with "St 3 On".
In this case, the absolute value is: Set Point + Bandwidth 1 +
Offset 2 + Bandwidth 2 + Differential 3.

A ramp is defined using ten points. Each point specifies a day number
and a set point for that day. Once the points of the ramp are defined,
the ramp must be activated. The controller will change the temperature set point every hour in a linear fashion between consecutive points
of the ramp. When the last point of the ramp is reached, the temperature set point for that day is maintained until the ramp is reactivated.
NOTES :
i) All ten points of the ramp must be specified. If ten 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 255.
- Decreasing day numbers are not allowed.
- Increasing temperatures are not allowed.

Humidity Compensation
The minimum speed of stage 1 can automatically be adjusted as a
function of relative humidity. As humidity increases, the minimum
speed increases proportionally to compensate for the change. At
humidity levels at or below the humidity set point, the minimum speed
is equal to the normal uncompensated speed. The user specifies the
percentage increase in minimum speed for a relative humidity equal
to the humidity set point + 10%. For example, if the minimum speed
is 40% and the compensation adjustment is 30%, the minimum speed
will be adjusted to 70% of full speed when the humidity rises 10%
above the humidity set point. In addition to adjusting the minimum
speed, the humidity compensation feature also changes the operation of the minimum ventilation cycle: if the controller is operating in
minimum ventilation mode when the relative humidity exceeds the
humidity set point, the minimum ventilation fans are operated continuously rather than cycled.

Minimum Ventilation Speed Ramp
The user can define a minimum ventilation speed ramp to adjust the
minimum speed of stage 1 automatically over a given time period. A
ramp is defined by ten points and each point specifies a day number
and a fan speed for that day. Once the points are defined, the minimum speed ramp must be activated. When the minimum speed ramp
is activated, the controller adjusts the minimum speed of state 1
fans every hour in a linear fashion between two consecutive points.
When the last point of the ramp is reached, the ramp is deactivated.
The controller maintains the minimum speed specified for this point
until the ramp is reactivated or until a new single minimum speed is
specified using the first method.

CURTAIN OPERATING TIME COMPENSATION
1. Normal Mode (Without Compensation)
The curtains open and close intermittently according to the specified
opening time, closing time and time off, as described on the preceding pages. There is no outside temperature compensation.
2. Progressive Mode (With Compensation)
The controller can use the current outside temperature to adjust the
opening and closing times of the curtains. This feature must be activated from the front panel (see below). An outdoor temperature
probe must be connected to input #5 for this feature to work.
Room Temperature Rises: When the curtains open, the controller
increases TIME ON by 5% for every 1°F (0.6°C) difference between
the outside temperature and the outside Set Point. The TIME OFF is
decreased by the same amount. This is true if the outside temperature is greater than the outside set point.
The higher the outside temperature, the time on increases, causing
the curtains to open faster.
Room Temperature Falls: When the curtains close, the controller
increases TIME ON by 5% for every 1°F (0.6°C) difference between
the outside temperature and the outside Set Point. TIME OFF is decreased by the same amount. This is true if the outside temperature
is lower than the outside set point.
The lower the outside temperature, time on increases, causing the
curtains to close faster.
NOTE: If, after compensation, the time off value is less than or equal
to ten seconds, it is set to zero.

ZONED HEATERS
To configure your system for zoned heaters, set internal switch # 8
to ON. Since the two heater outputs operate independently, different probes are assigned to each output: Probes 1 and 2 are assigned
to Heater 1 and Probes 3 and 4 are assigned to Heater 2. Individual
probes can be turned on or off using the internal switch settings. If
both probes are activated for a given heater, the average temperature from both probes is used; if they are not activated, the heater
uses the room temperature. If only one heater is active, heater 1
uses the room temperature.

Both heating zones can have negative and positive heater offsets.
Using a negative offset allows activating the heating output above
the temperature set point; this can be useful to control heat mats for
instance.
To avoid ventilation problems when using zoned heating, a special
protection is built into the device. Suppose the animals are young and
confined to one part of the building (zone 1) while the rest of the
building is heated at a minimum level (zone 2). If the temperature
difference between zones is too high and zone 1 fans operate according to the average temperature for both zones, cooling in zone 1
may be insufficient. A built-in protection will operate the fans according to the probes of the zone with the highest temperature whenever the temperature difference between zones is greater than a
user-defined value.

MEMORY CARD
The memory card is used to create a backup copy of your
controller's configuration. The card is also useful to transfer the
configuration of one controller to another controller of the same
type.
The switch at the bottom of the card is used to lock or to unlock
the card (
= locked,
= unlocked).

TO TRANSFER A CONFIGURATION:
1. Open the latch and lift the controller's cover.
2. If you are about to copy the controller's configuration on the memory
card, make sure the card's switch is at the unlocked position.
3. Insert the card in the connector located on the electric board
inside the controller. Refer to the illustration above to position the

5. Close the controller's cover.
6. The transfer menu should be displayed on screen. Use the
adjustment buttons to select whether you want to transfer the memory
card's content into the controller ("COPY" "to" "CTRL") or if you
wish to transfer the controller's content into the memory card
("COPY" "to" "CARD") .
7. Once you have chosen the proper type of transfer, press and
hold the Other Functions button for 5 seconds. The controller will
automatically return to the ROOM TEMP menu once the transfer is
completed. If the transfer is incorrect, the letters "COPY" and
"Error" will flash on screen. In this case, turn the adjustment knob
once to exit the error menu then refer to the table below to see
possible error causes.
8. Once the transfer is over, open the controller's cover, and remove the memory card from the connector. Close the controller's
enclosure afterwards.
9. Lock the card switch (

GLOSSARY
BANDWIDTH: The temperature interval over which the variablespeed fans of a given stage increase or decrease in speed proportionally to the temperature.
CASCADING HEATERS: Heaters operate in a sequence. As the average room temperature falls, additional heaters are turned on as
needed.
DEFAULT VALUE: A typical parameter setting defined at the factory.
DIFFERENTIAL: The differential is the temperature difference between the moment the constant-speed fans or heating units of a
given stage start running and the moment they return to a stop.
MINIMUM VENTILATION CYCLE: When the room temperature is
below the set point, the Stage 1 fans operate intermittently to provide minimum ventilation to the room.
MINIMUM VENTILATION SPEED RAMP: When Stage 1 operates
variable-speed fans, they will run at minimum speed during the minimum ventilation cycle. The user can define a minimum ventilation
speed ramp to adjust the Stage 1 minimum speed automatically over
a given time period. The minimum speed increases over time as the
animals grow.
OFFSET: An offset is a temperature difference from the set point
that normally defines a cut-off point for a stage operation. For example, a heater offset of 2°F means the heaters will turn off at 2°F
below the set point.
STAGE 1 RAMP: When the temperature rises to the point where
Stage 1 constant-speed fans are needed for cooling, the running time
of the fans is increased gradually from the minimum ventilation settings up to full operation. Likewise, when the temperature falls below the set point, the running time is decreased gradually until the
minimum ventilation settings are reached.
64 TC5-2N6FA rev.01
TC5-2N6FA
SET POINT: The set point is the target room temperature. When the
temperature is above the set point, the controller cools the room by
turning on the cooling fans. When the temperature is below the set
point, the controller heats the room by turning on the heaters.
TEMPERATURE RAMP: 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. The set point decreases
over time as the animals grow.
ZONED HEATERS: When zoned heaters are used, heaters in each
zone operate according to their own probes rather than the average
temperature for the entire room. In this way, heaters across zones
are independent of one another.
