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

KOOLMASTER PP-32 REV.01

PP-32

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

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

ALARM

There are two types of alarms on the market. One type activates when current is cut off at its input, whereas the other activates when current is supplied at its input. For an alarm of the first type, use the NC

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.

MINIMUM VENTILATION TIMER

OFF

In addition, fans' On-Time, in minimum ventilation, can automatically be adjusted over time by using a curve. Refer to section 5.15.2 for further information on the minimum ventilation curve.

Note that the minimum ventilation curve must be TURNED OFF in order to adjust minimum ventilation settings.

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.

KOOLMASTER PP-32 REV.01

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.

5.6 TUNNEL CURTAIN

The PP-32 allows you to control an endwall curtain for tunnel ventilation. The tunnel curtain is controlled either by the static pressure level in the barn or in timer mode, according to the room temperature. Select the proper mode (Timer or Static pressure) that is used to control the tunnel curtain in the installation setup (see sec 5.14.3).

In both modes, a minimum animal age is defined to avoid starting the tunnel ventilation mode when animals are too young.

Tunnel Curtain Controlled in Time Mode:

Every time a tunnel fan stage starts, the curtain opens according to the Open-Time related to this stage. A maximum running time is also set to limit the curtain's opening.

When the start temperature of the first tunnel stage is reached, the tunnel curtain opens during half of the opening time that is associated with this stage. When half of the opening time has elapsed tunnel fans are activated. When the next tunnel stage is reached, the tunnel curtain continues to open according to the opening time defined for that stage, etc. When the temperature decreases, the same sequence is executed in reverse order. The following diagram sums up the operation of the first two tunnel stages.

Tunnel Curtain Controlled by the Static Pressure:

When the pressure drops below the low pressure set point, the tunnel curtain closes according to a timer. Likewise, when the static pressure increases above the high pressure set point, the curtain opens according to another timer. The curtain only starts operating this way once the start temperature of the first tunnel stage has been reached.

When the curtain starts opening, it first opens during the pre-opening delay. Fans of the first tunnel stage are then activated.
