Main Features
LCD Display — An LCD display provides an
effi cient interface for displaying, monitoring
and adjusting parameter values.
Minimum Ventilation Cycle — When ven-
tilation is not required to reduce the room
temperature, fan outputs can run either con-
tinuously or intermittently to reduce humidity
levels and supply oxygen to the room.
Set point & minimum ventilation curves —
The controller can automatically change
the temperature set point and the minimum
ventilation level with time as the animals are
growing up.
History menus: History menus allow monitor-
ing the sensor readings and verify the run time
of some outputs. The controller comes with
the following histories menus:
Min & Max sensor readings:
Inside temperature sensors ..........7 days
Outside temperature sensor .........7 days
Humidity sensor ..........................7 days
Static pressure sensor .................7 days
Daily water consumption ...........60 days
Run time of each heater ............ 75 days
Run time of each feeder ............. 75 days
Alarm management — Alarms are provided for
high-low temperatures, defective probes and
other system functions. Alarm states are kept
in memory until they are acknowledged even
if alarm situation has been rectifi ed.
Humidity Control — The control offers many
ways to compensate for high or low humid-
ity levels.
6 temperature sensors — Up to six tem-
perature sensors can be connected to the
controller to obtain an accurate reading of
the average room temperature and a faster
reaction time.
Control of the air inlet movement — The
movement of air inlets can be coordinated
with the operation of the fans using a po-
tentiometer located on the panel drive or a
timer. This allows the air inlets to be adjusted
correctly, without the infl uence of uncontrol-
lable factors such as wind or air from adjoin-
ing rooms.
De-icing/purge cycle — An automatic de-
icing/purge function can be used to de-ice
the curtains or purge the air in any weather
conditions.
Password protection — A password can be
enabled to restrict access to the setup func-
tions of the controller.
Backup battery — A backup battery allows
the unit to keep time in case of a power
failure.
Overload and overvoltage protection — Re-
settable fuses are provided at low-voltage
inputs of the controller to protect its circuitry
in the case of an overload or overvoltage.
Computer control — The controller can be
connected to a computer, thus making it
possible to centralize the management of
information and diversify control strategies.
Test mode — A test mode allows you to simu-
late temperature changes and verify controller
performances.
2. MOUNTING INSTRUC-
TIONS
2.1.
Installing the Controller
on the Wall
Fasten the two metal brackets on the mount-
ing holes located behind the controller using
six screws. Then, mount the enclosure on
the wall using four other screws. Leave a
clearance of at least 16" to the left of the
enclosure to allow the cover to be removed
for maintenance.
2.2.
Connections
2.2.1. Main Wiring
Refer to the wiring diagram enclosed with this
user's manual to connect the controller. Drill
holes at the bottom of the enclosure to pass
the wires and install watertight connectors to
prevent water from entering in the enclosure.
Do not make any holes at the side and top of
the enclosure.
All wiring must be done by an autho-
rized electrician and must comply with
applicable codes, laws and regulations.
Make sure power is off before doing any
wiring to avoid electrical shocks and
equipment damage.
Do not install rigid conduit into electrical
knockouts. Only nylon cable glands are
permitted for cable or wire fastening.
The controller has no power-on switch.
An external switch or circuit breaker
shall be included in the building instal-
lation to interrupt power to L and N
electric power lines. It shall be in close
proximity to the equipment and within
easy reach of the operator. It shall be
marked as the disconnecting device for
the equipment.
2.2.2. Alarm Connection
There are two types of alarms on the market.
One type activates when current is cut off at its
input; the other type of alarm activates when
current is supplied at its input. For an alarm of
the fi rst type, use the NC terminal as shown on
the wiring diagram. For an alarm of the second
type, use the NO terminal.
2.2.3. Sensor Inputs
Sensors operate at low voltage and are
isolated from the supply. Make sure that
sensor cables remain isolated from all high
voltage sources. In particular, do not route
the sensor cables through the same electri-
cal knockout as other cables. Do not connect
the shield from the sensor cable to a terminal
or a ground.
Extending a sensor: Each sensor can be ex-
tended up to 500 feet (150 meters).
To extend a sensor: Use a shielded cable of
outside diameter between 0.245 and 0.260 in
(6.22 and 6.60 mm) (the cable dimensions
