1. PRECAUTIONS
We strongly recommend installing supplementary natural ventilation as well as a backup 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 excessive
humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

2. FEATURES
The PP-32 is an electronic device used for environmental control in livestock
buildings. It allows the user to maintain a specified target temperature by
controlling the operation of ventilation and heating equipment. Eight heater
stages, 16 fan stages, a tunnel curtain, 2 auxiliary outputs, vent doors and 4
clock outputs can be controlled. Fan stages can be configured to activate
cooling systems in timer mode. In all, the PP-32 provides up to 32 relay
outputs. In addition, up to 12 DWR-F-1A air inlet controllers can be connected to the PP-32.
The main features of the PP-32 are as follows:
LCD DISPLAY
An LCD display provides an efficient interface for displaying, monitoring and
adjusting parameter values.
MINIMUM VENTILATION CYCLE
When ventilation is not required for reducing room temperature, on-off fan
outputs can be operated either continuously or intermittently to reduce the
level of humidity and supply oxygen to the room.
TEMPERATURE AND MINIMUM VENTILATION CURVES
The controller can automatically change the temperature set point and the
minimum ventilation's On-Time over a given period of time in accordance
with the user's requirements.
AVERAGE TEMPERATURE READINGS RECORDED FOR THE PAST 60 DAYS
The average temperature readings are logged into the controller's history for
the past 60 days.
INDIVIDUAL SENSOR READINGS RECORDED FOR THE PAST 10 DAYS
The minimum and maximum readings of each sensor (temperature & humidity
sensors) are logged into the controller's history for the past 10 days.
WATER AND HEATER MONITORING
A pulse input is provided to monitor the water consumption. Heater run times
are also logged into an history. These values are recorded for the current day
and for the previous 60 days.
ALARM MANAGEMENT
Alarms are provided for high-low temperatures, defective sensors and other
system failures. The controller keeps in memory the 10 most recent alarms.
KOOLMASTER PP-32 REV.01
7
PP-32
EIGHT INDEPENDENT TEMPERATURE SENSOR INPUTS
Up to eight temperature sensors can be connected to the controller in order to
obtain a more accurate reading of the average room temperature and a faster
reaction time. Sensors may be assigned to each heater output or to auxiliary
outputs. Auxiliary outputs can be used to operate various devices such as
heating units or stir fans for instance.
OUTSIDE TEMPERATURE SENSOR
HUMIDITY COMPENSATION
Three mechanisms can be used to compensate for a high humidity level:
1. Fans' On-Time, in minimum vent. cycles, can automatically be increased.
2. Kool-Cel or mist units can be shutoff.
3. Heaters can be activated in timer mode.
STATIC PRESSURE & VENT DOORS & TUNNEL CURTAIN CONTROL
A static pressure input is provided to control static pressure by opening and
closing the vent doors and/or tunnel curtain.
CONTROL OF AIR INLET MOVEMENT
If the PP-32 is used in combination with one or more DWR-F-1A controllers,
the movement of air inlets can be coordinated with the operation of the fans
using a potentiometer located on the panel drive. This allows the air inlets to
be adjusted correctly, without the influence of uncontrollable factors such as
wind or air from adjoining rooms.
PASSWORD PROTECTION
A password can be enabled to restrict access to the controller setup functions.
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 and outputs 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 simulate temperature changes and verify controller
performance, as well as manually activate each output sequentially.

Sensors operate at low voltage and are isolated from the
supply. Be 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 extended 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.
CAUTION: Do not run sensor cables next to other power cables. When
crossing over other cables, cross at 90°.
Defective temperature sensors: An alarm is generated when a defective
sensor is detected. The defective temperature sensors are identified in
the "15. Alarm Log" menu. Press the key to directly access this
menu.
2. ALARMS

5.2 CONTROLLER PROGRAMS
The controller allows to use up to 4 separate programs to control the
room temperature. It then becomes possible to activate a specific
program, that uses particular fan settings, in accordance with the animal
age for instance.
Relays that are activated on fan stages 1-4 vary depending on the chosen
program: the first 4 fan stages use separate relay assignment settings for
each program. This allows to activate a greater number of fans as the
occupied space in the barn increases. Fan stage's sensor assignment must
also be set separately for each program in use.

5.4 MINIMUM VENTILATION
PRINCIPLE OF OPERATION
When the room temperature is below the set point, fans can operate
according to a timer. The minimum ventilation cycles runs stage 1 fans
according to a timer as shown below. Running fans even though ventilation is not required for reducing the room temperature is useful to reduce
the humidity level and supply oxygen to the room. It also prevents the
fans from freezing in winter.

5.5 INLET / VENT DOOR SETTINGS
The PP-32 controller can operate the air inlets / vent doors in two
different ways:
1. Inlets' positions can be determined by using a potentiometer feedback
controller (DWR-F-1A). Refer to the installation setup section to
enable DWR-F-1A modules. Note that the static pressure sensor must
be deactivated in order to activate the air inlets (see sec. 5.15.3).
2. Inlets' positions can be determined by the static pressure level in the
barn. In this case, a static pressure sensor is required and must be
activated during the installation setup (see sec. 5.15.3). The term
"Vent Door" is used to refer to an air inlet that is controlled by the
static pressure.
5.5.1 Inlet Settings (Potentiometer Feedback from Inlets)
If air inlets operate according to potentiometer feedback modules (DWRF-1A), the PP-32 controller adjusts the air inlets opening according to
ventilation stages. As the temperature increases and new stages are
activated, the inlet is opened or closed accordingly. The air inlet position
is directly related to these ventilation stages. Refer to the DWR-F-1A
instruction manual to program inlet openings.
In addition, a compensation can be activated to ensure the uniformity in
room temperature: air inlet positions are automatically adjusted when the
reading of the sensors that are associated with the air inlet differs from
the average room temperature.
5.5.1.1 Setting DWR-F-1A's ID numbers
ID numbers must be assigned to each DWR-F-1A modules. This allows to
establish the communication with the PP-32 control and the external
modules. The following table gives the proper ID numbers for each
DWR-F-1A module.

5.5.1.2 Adjusting the Air Inlet Compensation
The compensation is expressed as a percentage per degree difference
between the average controller's temperature and the average temperature of sensors that are assigned to the inlet. It determines by how much
the inlet must open or close to help reduce the temperature differences
in the building. For each degree above or below the average temperature, the inlet will open or close using the compensation value assigned
by the user. For example, if the compensation value is set to 5%/°F and
the inlet's sensors read 3°F above the average controller temperature,
the inlet will open of 15% to help decrease the temperature in that zone.
The compensation can be adjusted from 0 to 10% of inlets' opening or to
"Off" to deactivate this function.
Select "8.Inlet Settings" from the main menu using the navigation
buttons then press the right-arrow key. Note that this menu is only
available if the static pressure sensor is disabled and if inlets have
been activated (see sec. 5.15.3).
Press the right-arrow key once
again to select "1.Inlet Comp"
menu. The compensation value of
each air inlet is displayed.
Use the up or down-arrow key to
select the desired inlet.
Use the adjustment buttons to set
the compensation to the proper
value. Press the left-arrow key to
exit this menu.

5.5.2 Vent Door Settings
If a static pressure sensor is used, the PP-32 can control the static
pressure in the room by opening and closing vent doors. When the
pressure drops below the low pressure set point, the vent doors close
according to a timer. Likewise, when the static pressure increases
above the high pressure set point, the vent doors open according to a
timer. It is also possible to define a stage level above which the vent
doors will always remain closed. Refer to sec. 5.15.3 to activate the
static pressure sensor.

In minimum ventilation, the vent doors open during the pre-opening delay
before fans start running. The same delay is used to close the vent doors
when the stage 1 fans return to a stop.
Static Pressure Alarm: alarms can be set off if the static pressure
remains below or exceeds a certain level for a too long period of time. In
this case, a delay is set in order to activate the alarm: the alarm condition
must maintained during this delay before the alarm is set off. Refer to
section 5.13.2 to set the static pressure alarm settings.

GROUPS OF STATIC PRESSURE SET POINTS :
Two groups of static pressure set points can be defined. HI and LO static
pressure set points #2 start being used either when a certain ventilation
stage is reached or when the outside temperature decreases below a
user-define value. The following graphs sum both cases:
1. Static pressure set points' transition according to ventilation stages:
Example: when the start temperature of stage 5 is reached, the vent
doors start operating according to the second group of static
pressure set points. The first group of set points is being used
once again when the room temperature drops below the stage
5 stop temperature.

When the static pressure level in the room exceeds the hi or low set
points, the vent doors start opening or closing according to a cycle, as
explained below:
Open Time: when the static pressure exceeds the Hi pressure set point,
the vent doors open during this delay. The open time ranges from 0 to
900 seconds.
Close Time: when the static pressure drops below the Lo pressure set
point, the vent doors close during this delay. The close time ranges from
0 to 900 seconds.
