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 exces-
sive humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

The TC5-2V2SA 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.
Two stages of variable speed fans can be connected to the controller, as
well as two stages of either constant-speed fans or heating units. In addi-
tion, one of the constant-speed fan stages can be configured as a mist
cooling stage.
Themainfeaturesof the TC5-2V2SAareas 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 TYPES
Thevariationinmotorspeed resulting from achangeinvoltagewill depend
onthemakeand capacity of themotor. Inorderto achieve a high degreeof
compatibilitybetweencontrollerandmotor, theusercan choosefromamong
tendifferentmotortypes,thusensuring that the correct voltageissupplied.

HUMIDITYCOMPENSATION
Thestage1minimumspeed can be adjustedautomaticallyasafunction of
relative humidity. As humidity increases, the minimum speed of stage 1
fans increases proportionally to compensate for the change.
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.
DE-ICINGCYCLE
Ade-icingcycleisprovidedfor de-icing stage 2 variable-speed fansincold
weatherconditions.
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.
OVERLOADAND OVERVOLTAGEPROTECTION
Fuses are installed at the input and outputs of the controller to protect its
circuitryinthecaseof an overload orovervoltage.
COMPUTERCONTROL
The controller can be connected to a computer, thus making it possible to
centralizethemanagementofinformation and diversify controlstrategies.
CONTROL OF AIR INLET MOVEMENT
IftheTC5-2V2SA is usedincombinationwith a PF-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.
TEST MODE
Atestmodeallows you to simulatetemperaturechangesand verify control-
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 and Stage 2 according to the type of fan motors used.
