PRECAUTIONS

We strongly recommend installing supplementary natural ventilation, a failure alarm system as well as a back-up 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 supply circuit as well as an external relay on all ON-OFF stages to prolong the life of the controller.

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

FOR CUSTOMER USE

Enter below the serial number located on the side of the controller and retain this information for future reference.

FEATURES

The SS 5025 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. Four stages of constant-speed fans can be connected to the controller, as well as curtains for natural ventilation and two stages of either constant-speed fans or heating units. In addition, the last cooling stage can be configured as a mist cooling stage.

The main features of the SS 5025 are as follows:

THREE-DIGIT DISPLAY

A three-digit display provides a high level of accuracy, allowing the user to specify a temperature to within one tenth of a degree (in Fahrenheit or Celsius units).

PILOT LIGHTS

Pilot lights indicating the state of outputs allow the user to monitor the operation of the system without having to enter the building.

MINIMUM VENTILATION CYCLE

When ventilation is not required for cooling, the first stage fans can be operated either continously or intermittently to reduce the level of humidity and supply oxygen to the room.

MINIMUM VENTILATION COMPENSATION CURVE

An outside probe can be connected to the controller to adjust the minimum ventilation cycle as a function of outside temperature.

RAMPING OPTION ON STAGE 1 FANS

The running time of the fans can be increased (or decreased) gradually to smooth out the transition between the minimum cycle and full operation of

Stage 1 fans.

ZONED OR STAGED HEATERS

QM 1313.rev.02

SS 5025

FOUR INDEPENDENT TEMPERATURE PROBE INPUTS

Up to four temperature probes can be connected to the controller in order to obtain a more accurate reading of the average room temperature and a faster reaction time.

TEMPERATURE CURVE

The controller can be set to automatically change the temperature set point over a given period of time in accordance with the user's requirements by specifying a temperature curve with up to six different points.

OUTSIDE TEMPERATURE COMPENSATION ON CURTAIN SPEED

Curtain opening and closing times can be adjusted as a function of outside temperature.

OVERLOAD AND OVERVOLTAGE PROTECTION

Fuses are installed at the input 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.

CONTROL OF AIR INLET MOVEMENT

If the SS 5025 is used in combination with a SB 2000 controller, the movement of the air inlets can be coordinated with the operation of the fans using a potentiometer located on the curtain machine or baffle actuator. This allows the air inlets to be adjusted correctly, without the influence of uncontrollable factors such as wind or air from adjoining rooms.

HIGH/LOW TEMPERATURE ALARM OUTPUT

Temperature alarm monitoring includes outside temperature compensation in cases where the outside temperature is high.

EMPERATURE PROBES

1 Connecting the Probes

The controller is supplied with one room probe connected to input # 1. Three additional probes can be connected to inputs # 2, 3 and 4 and an outside probe can be connected to input # 5 (see wiring diagram enclosed). If zoned heating is used, Heater A uses probes 1 & 2 and Heater B uses probes 3 &

4. If staged heating is used, the average temperature from activated probes

# 1, 2, 3 and 4 is used.

CAUTION

:

Probes operate at low voltage and are isolated from the supply. Be sure that probe cables remain insulated from all high voltage sources. In particular, do not route the probe cables through the same electrical knockout as other cables. Do not connect the shield from the probe cable to an input or a ground.

QM 1313.rev.02

SS 5025

2 Extending the Probes

Each probe can be extended up to 500 feet (150 meters). To extend a probe: n

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.

n

It is preferable to solder the cable joint to ensure a proper contact between the two cables.

CAUTION:

Do not run probe cables next to other power cables. When crossing over other cables, cross at 90°.

3 Installing the Outside Probe

n

Run the outside probe cable on the north side of the building, 6 ft (2 m) below the eave, inside a pale colored conduit. Avoid installing the probe in direct sunlight or exposed to the rain.

n

Be sure the probe cable is isolated from sheet metal or any other conductive material.

INIMUM VENTILATION COMPENSATION

The SS 5025 has the capability of automatically adjusting the running time of the minimum ventilation fans as a function of outside temperature. As the weather gets colder, the on time is decreased gradually to compensate for the change. This can help reduce costs by reducing the ventilation when it is not required. A curve is used to calculate the required compensation as a percentage of current on time (see following page). Only the running time is adjusted; the total cycle time remains unchanged. Note that internal switches # 7 and 9 must be set to ON for this feature to work.

To configure your system for zoned heaters, set dipswitch # 5 to ON. Since the two heater outputs function independently, different probes are assigned to each output: Probes 1 & 2 are assigned to Heater A and Probes 3 & 4 are assigned to Heater B. Individual probes can be turned on or off using the push-button functions contained in the ROOM TEMPERATURE function (see section on Temperature Settings).

Note that the heaters can become active only if the average temperature from all activated probes is below the set point. If this isn't the case, the heaters will not turn on even if individual probe temperatures are below the set point (this condition applies only if both off temperatures are below the set point).
