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 on the outputs of the controller protect its cir-
cuits 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 exces-
sive humidity, it is preferable to install it in a corridor.
DO NOT SPRAYWATER ON THE CONTROLLER

The TC5-1N5FAB 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.
Onestageofvariablespeed fans, up totwostagesofconstant-speed fans,
as well as curtains, foggers and heaters can be connected to the controller.
Themainfeatures oftheTC5-1N5FAB are as follows:
THREE-DIGITDISPLAY
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 Cel-
sius 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.
MINIMUMVENTILATION CYCLE
Whenventilationisnot requiredforcooling,the first stagefanscan be oper-
atedeithercontinuouslyor intermittently to reducethelevelof humidity and
supply oxygen to the room.
TEMPERATUREAND MINIMUMVENTILATION SPEEDCURVES
Thecontrollercanbeset to automaticallychangethetemperatureset point
andtheminimum ventilationspeedover agivenperiod oftimeinaccordance
withtheuser'srequirementsby specifying a temperature curveandamini-
mum ventilation speed curve with up to six different points each.
CHOICE OF TEN MOTOR CURVES
Thevariationinmotorspeed resulting from achangeinvoltagewill depend
onthemakeand capacity of themotor. Inorderto achieve a high degreeof
compatibilitybetweencontrollerandmotor, theusercan choosefromamong
tendifferentmotorcurves, thus ensuringthatthecorrect voltage issupplied.
HUMIDITYCOMPENSATION
Thestage1minimumspeed can be adjusted automaticallyasafunctionof
relative humidity. As humidity increases, the minimum speed of stage 1
fans increases proportionally to compensate for the change.
FEATURES

TC5-1N5FAB rev.06
TC5-1N5FAB
RAMPING ON STAGE 1: 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 drops below the set
point, the running time is decreased gradually until the minimum ventila-
tion settings are reached.
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 CURVE: The controller can be set to automatically
change the temperature set point over a given period of time in accor-
dance with the user's requirements. The set point decreases over time as
theanimalsgrow.
ZONED HEATERS: Whenzonedheaters are used, heaters ineachzone
operateaccordingtotheir own probes ratherthantheaverage temperature
for the entire room. In this way, heaters across zones are independent of
oneanother.

GLOSSARY
BANDWIDTH: Thetemperature interval withinwhichthe variable-speed
fans of a given stage increase or decrease in speed proportionally to the
temperature.
CASCADING HEATERS: Heaters operate in a sequence. As the
averageroomtemperaturedrops, additional heatersareturnedon as
needed.
CURTAIN DEAD BAND: Thedeadbandis the temperaturedifference
between the opening and closing temperatures of the curtains. Within
this interval, the curtains are at rest.
DEFAULT VALUE: Atypical parameter setting defined at the factory.
DIFFERENTIAL: Thedifferentialis thetemperaturedifference between
the moment the constant-speed fans or heating units of a given stage
start running and the moment they return to a stop.
HYSTERESIS: A hysteresis is used to smooth the transition from one
state to another. For example, when the temperature drops to the cut-off
point for a stage of constant-speed fans, the fans will actually be cut off at
slightly less than the cut-off point. This way, if the temperature fluctuates
around the cut-off point without dropping significantly below it, the control-
ler will not oscillate between two states. For example, if the hysteresis is
0.3°F and the stage 2 fans are programmed to be cut off at 75°F, the cut-
off will actually occur at 74.7°F.
MINIMUM VENTILATION CYCLE: Whentheroomtemperature is below
the set point, the Stage 1 fans operate intermittently to provide minimum
ventilation to the room.
MINIMUM VENTILATION SPEED CURVE: WhenStage1operates
variable-speed fans, they will run at minimum speed during the minimum
ventilationcycle. Theusercandefinea minimum ventilation speed curve
to adjust the Stage 1 minimum speed automatically over a given time
period. Theminimumspeedincreasesovertime 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.

HIGH/LOW TEMPERATUREALARM OUTPUT
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
maximumvoltagetothevariable speed fansduringthe2seconds immedi-
ately following each start-up.
FOURINDEPENDENT TEMPERATURE PROBE INPUTS
Uptofour temperature probescanbe connected tothecontroller in orderto
obtain a more accurate reading of the average room temperature and a
faster reaction time.
OUTSIDETEMPERATURE COMPENSATION ON CURTAINSPEED
Curtain opening and closing times can be decreased as a function of out-
sidetemperature.
OVERLOADAND OVERVOLTAGEPROTECTION
Fuses and other protection devices are installed on the outputs of the con-
troller to protect its circuitry in the case of an overload or overvoltage.
COMPUTERCONTROL
The controller can be connected to a computer, thus making it possible to
centralizethemanagementofinformation and diversify controlstrategies.
CONTROL OF AIR INLET MOVEMENT
IftheTC5-1N5FABisused incombinationwith aPF-5Bcontroller,themove-
mentoftheair inletscanbecoordinated with theoperationof the fansusing
a potentiometer located on the panel drive. This allows the air inlets to be
adjusted correctly, without the influence of uncontrollable factors such as
windorairfromadjoining rooms.

lerperformance.

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
capacityofthemotor. Thevariousmotorsavailableintheindustryhavebeen
dividedintotencategoriesandthe controller has been programmedwitha
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.

ALARMSETTINGS
The controller sets off an alarm in the case of a power failure, a fault in the
supply circuit or a high or low temperature. Temperature alarms are de-
fined according to the set point as shown in the diagram below.

feature. A thirdparameter,calledthe criticalhightemperature,is defined to
continue monitoring the indoor temperature for high temperatures. When
the indoor temperature reaches the critical high temperature (defined as
an absolute value), an alarm is set off.
