KOOLMASTER PP20-VS2
Main Features
1.4.
Very large LCD display:
A large LCD screen
provides an efficient interface for displaying,
monitoring and adjusting the parameters.
3 Controller programs:
The controller allows
using 3 different programs to control the
room temperature. It is thus possible to acti-
vate a specific program, that uses particular
temperature settings, in accordance with the
animal age for instance.
Status LEDs:
Pilot lights that indicate the
status of the controller outputs are located
on the faceplate of the controller. These leds
allow monitoring the system’s operation with-
out having to enter the building.
Minimum ventilation cycle:
When ventilation
is not required to reduce the room tempera-
ture, the fan outputs can run either continu-
ously or intermittently to reduce humidity
levels and supply oxygen to the room.
8 Indoor temperature sensors:
Up to eight
temperature sensors can be connected to
the controller to obtain an accurate reading
of the average room temperature and a faster
reaction time.
Natural ventilation curtains:
The controller
can open 2 natural ventilation curtains and
stop all ventilation when the outside tempera-
ture is sufficiently warm.
Tunnel ventilation:
When the room tempera-
ture rises, tunnel ventilation reduces the ac-
tual temperature perceived by the animals.
Humidity control:
The inside and outside
relative humidity sensors allow controlling
humidity levels in the room.
0-10V outputs:
Two 0-10v outputs can be
used to control additional variable fan stages,
heating devices, and/or inlets.
Control of the air inlet movement:
The move-
ment of air inlets can be coordinated with the
operation of the fans using a potentiometer lo-
cated on the panel drive or a timer. This allows
the air inlets to be adjusted correctly, without
the influence of uncontrollable factors such
as wind or air from adjoining rooms
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:
Room temperature ................60 days
Inside temperature sensors .... 10 days
Outside temperature sensor ... 75 days
Inside humidity sensor .......... 75 days
Outside humidity sensor ........ 75 days
Static pressure sensor ........... 75 days
Run time of each heater
....... 75 days
Run time of each feeder
........ 75 days
Daily water consumption
....... 75 days
Alarm management
The controller provides alarms for high-low
temperatures, defective sensors and other
system failures. It keeps in memory the 20
most recent alarm conditions.
Password protection
A password can be enabled to restrict access
to the setup functions of the controller.
Backup battery
A backup battery allows the unit to keep time
in case of a power failure.
Overload and overvoltage protection
Resettable 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 com-
puter, thus making it possible to centralize
the management of information and diversify
control strategies.
Test mode
A test mode allows you to simulate tem-
perature changes and verify controller per-
formances.
2. MOUNTING INSTRUC-
TIONS
Installing the Controller
2.1.
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.
Connections
2.2.
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.
