INTRODUCTION1.
Precautions1.1.
WARNING: Read and save these in-
structions!
Safety may be jeopardized if the equipment is
used in a manner not specified by the manu-
facturer. Carefully read and keep the following
instructions for future reference.
We strongly recommend installing supplemen-
tary natural ventilation as well as a backup
thermostat on at least one cooling stage.
Although fuses at the input and outputs of
the controller protect its circuits in case of
an overload or over-voltage, 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). Indoor use only!
To avoid exposing the controller to harmful
gases or excessive humidity, it is preferable
to install it in a corridor.
If the equipment is used in a manner not
specified by the manufacturer, the protec-
tion provided by the equipment may be
impaired.
Do not spray water on the controller! In
order to clean the control, wipe it with a
damp cloth.
Before servicing or cleaning unit, switch
power off at service panel and lock the
switch disconnecting means to prevent
power from being switched accidentally.
When the service disconnecting means
cannot be locked, securely fasten a
prominent warning device, such as a
tag, to the service panel.
Symbols of the Manual1.2.
Warning. Read the following text
carefully; it contains important
information which, if ignored, may
cause the controller to operate
improperly.

shock. Read the message and follow
the instructions carefully.
Pay attention. The following text
contains very useful information.
Press on the proper menu selector.
Press the “Current Conditions” push-
button.

KOOLMASTER PP20-VS2
Main Features1.4.
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 wh en th e out side tempe ra-
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 potentiome te r 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 Controller2.1.
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.
Connections2.2.
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.

KOOLMASTER PP20-VS2
Alarm Connection2.2.2.
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 first 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 electrical
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
should not be under 18 AWG) to ensure the
cable entry is liquid tight. Do not ground
the shielding.
It is preferable to solder the cable joint to
ensure a proper contact between the two
cables.
Do not run sensor cables next to other
power cables. When crossing over other
cables, cross at 90°.
Defective sensors: An alarm is generated
when a defective sensor is detected. De-
fective sensors are identified in the “Alarm
Log” menu. Refer to chapter 12 for further
information on the alarms.
2.2.4. 0-10V Output Connection
It is recommended to use a 18 to 22 AWG
wire to connect the devices to the 0-10V
outputs. This type of output can be used to
connect various devices such as heat mats
or fans.

the controller’s performances. When it is
enabled, all outputs of the controller operate
according to the simulated inside and outside
temperature and according to the simulated
level of relative humidity.

Set the following parameters:2.
Set point settings are common to all
programs of the controller.
Current set point — This is the current tem-
perature set point in use. This value cannot
be changed; to modify the set point, change
the day or night set points below.
Day s et po i nt — Set the temperature set point
that is used during the day (this set point is
used all day long if the night set point is not
enabled). The controller can also change the
day set point automatically over time by us-
ing a curve (see section 5.2). *This parameter
can only be modied while the temperature curve is
inactive (sec. 5.2).
Night set point — A different temperature
set point can be used at night. The night set
point can be used to lower the target room
temperature for instance. The night set point
is relative to the day set point, which means
that it is automatically adjusted when the day
set point changes. Set the night set point to
the de sired value. *Accessible if the night set point
is enabled (see section 4.10).
Clean mode set point — Select what is the
target room temperature while the controller
operates in clean mode.
Ou t sid e s et p o i nt — The controller can adjust
the moving speed of natural ventilation cur-
tains as a function of outside temperature.
When this function is used, the controller
refers to the outside temperature set point
to control the moving speed. Set the outside
temperatu re to the desired value. *Accessible if
the outside temperature sensor is enabled in section
4.7.1 and if the curtain compensation is enabled in
the Installation Setup (section 4.5).
5.2. Temperature Curve
Principle of Operation5.2.1.
The controller can automatically adjust the
target room temperature (day set point) over
time by using a curve.
A curve is composed of 10 steps. Each step
specifies a day number and a temperature set
point for that day (the day number refers to
the animal age). Once the curve is activated,
the controller changes the set point every
hour in a linear fashion between consecutive
steps of the curve. When the last step is
reached, the controller keeps using the tem-
perature set point associated to that day.

The following parameters can only be
modified while the curve is off.
If the curve is running, it is still possible
to adjust the set point value of all curve
steps simultaneously with the curve
offset parameter (see sec. 5.2.3).
Set the following parameters:2.
Current day — This is the current age of the
animals. This value may be changed to move
backward or forward on the curve. A change
in the current day also changes the animal
age in the “Age & mortality” menu.
Set point — The day set point is displayed.
Day numbers — Set the day at which each
step starts. The day number refers to the
animal age. It is adjustable from -5 to 450
days. Negative values are used to prepare
the house before letting the animals enter.
*This parameter can only be modied while the
curve is disabled.
Te m per atu re se t poi n ts — Assign a temperature
set point to each step of the cur ve. *This param-
eter can only be modied while the curve is disabled or
by using the curve offset function (sec. 6.1.3).
Status — Select “Yes” to activate the curve.
Once the curve is on, the controller auto-
matically adjusts the set point automatically
between consecutive points of the curve; for
this reason, curve steps cannot be modified
while the curve is running.

VENTILATION & COOLING6.
6.1. Minimum Ventilation
Minimum Ventilation Cycles6.1.1.
Definition: Minimum ventilation cycles are
activated when the average room temperature
is below the start temperature of fan stage 1.
Running the fans even though ventilation is
not required for reducing the room tempera-
ture is useful to reduce humidity levels and
supply oxygen to the room. It also prevents
the fans from freezing in winter.
Minimum ventilation timer: The minimum
ventilation timer is composed of an “On Time”
and of a “Cycle Time”. The fans stay on during
the “On Time” then stop until the end of the
cycle. This timer is common to all programs
of the controller.

Minimum ventilation fans: If variable outputs
are enabled, minimum ventilation cycles are
ensured by the variable-speed fans of stage 1
and by chosen On/Off fans (optional). If vari-
able outputs are not used, minimum ventila-
tion is ensured by On/Off fans only. Refer to
section 4.8.2 to assign these On/Off fans
and refer to section 4.9 to assign variable
fans to stage 1.
Automatic adjustment of the min. vent. rate
If variable-speed fans are used in minimum
ventilation, the controller can automatically
increase the minimum ventilation rate over
time with curves: a curve can be defined to
increase the minimum ventilation fan speed
over time and another curve can be defined to
increase the run time of the fans. *Refer to sec-
tion 4.5 to enable the Speed and/or the On Time curve
and refer to section 6.1.3 to dene these curves.
Night fan speed: If the nighttime minimum
ventilation function is enabled (section 4.10),
you can select another minimum ventilation
fan speed which will be used at night.

ventilation speed of each variable fan; this is
the speed of the fans during the “On Time”
portion of minimum ventilation cycles. If night
minimum ventilation is enabled in section
4.10, set the minimum speed separately for
day and night. Also note that the minimum
venti latio n spee d must b e hig her than the ab -
solute minimum speed of the variable output
(as defined in section 4.5). *This parameter is
accessible if variable fans are assigned to stage 1. In
addition, this parameter can only be modied while
the speed curve is inactive (sec. 6.1.2.2).
Variable 1-2 status — Set the status of each
variable output: select “On” if the output is
used in minimum ventilation; select “Off ” if
it is not. *This parameter is accessible if variable
fans are assigned to stage 1.
On Time & “Cycle Time” of Var. outputs 1-2 —
Set the minimum ventilation timer separately for
each variable output. The timer is composed of
an “On Time” and “Cycle Time” . Note that the
“Cycle Time” includes the “On Time”, it must thus
be longer than the “On Time”. *This parameter is
common to all programs.
Min Speed Stage 2+ for Var. Outputs 1-2 —
Set the speed at which each variable output
starts running at the beginning of stage 2 and
beyond (see sec. 6.2).

6.1.3. Minimum Ventilation Curve
A curve is composed of 10 steps. Each step
specifies a day number and a minimum ven-
tilation speed (or “On Time”) for that day (the
day number refers to the animal age). When
the curve is activated, the controller changes
the minimum ventilation speed or the fan “On
Time” every hour in a linear fashion between
consecutive steps of the curve. When the last
step is reached, the controller keeps using the
speed (or “On Time”) associated to that day.
