TC5-2V4SA rev.06
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 TC5-2V4SA 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 constant-speed fans and two stages of either con-
stant-speedfansorheatingunits.Inaddition, one of the constant-speed fan
stages can be configured as a mist cooling stage.
ThemainfeaturesoftheTC5-2V4SAareas 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
Whenventilationisnotrequiredforcooling, the first stage fans can be oper-
atedeithercontinuouslyorintermittentlytoreducethelevelofhumidityand
supply oxygen to the room.
TEMPERATUREAND MINIMUM VENTILATIONSPEED CURVES
Thecontrollercanbeset to automatically change the temperature set point
andtheminimumventilation speed overagivenperiodof time inaccordance
withthe user's requirements by specifying a temperature curve and a mini-
mum ventilation speed curve with up to six different points each.
CHOICE OF TEN MOTOR TYPES
Thevariationin motor speed resulting from a change in voltage will depend
onthemakeandcapacityofthemotor. Inorderto achieve a high degree of
compatibilitybetweencontroller andmotor,theuser canchoosefromamong
tendifferent motor types, thus ensuring that the correct voltageissupplied.

HUMIDITYCOMPENSATION
Thestage1 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.
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 fans during the 2 seconds immedi-
ately following each start-up.
DE-ICINGCYCLE
Ade-icing cycle is provided for de-icing stage 2variable-speedfans in cold
weatherconditions.
FOURINDEPENDENT TEMPERATURE PROBE INPUTS
Uptofourtemperatureprobescan be connected to the controllerinorderto
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
circuitryinthecase of an overload or overvoltage.
COMPUTERCONTROL
The controller can be connected to a computer, thus making it possible to
centralizethemanagementof information and diversify control strategies.
CONTROL OF AIR INLET MOVEMENT
IftheTC5-2V4SA is used in combination with a PF-5B controller, the move-
mentoftheairinletscanbe coordinated with the operation of 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
windorair from adjoining rooms.

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
dividedinto ten categories and the 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.
