Westronglyrecommendinstalling supplementarynatural ven-
tilationaswell 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 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 exces-
sive humidity, it is preferable to install it in a corridor.
DO NOT SPRAY WATER ON THE CONTROLLER

OVATION 214
FEATURES
The OVATION 214 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 equip-
ment. Two stages of variable speed fans, two stages of constant speed
fans, one curtain as well as foggers and heaters can be connected to the
controller.
The main features of the OVATION 214 are as follows:
FIVE-DIGIT DISPLAY
A five-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 continuously or intermittently to reduce the level of hu-
midity and supply oxygen to the room.
RAMPING FUNCTIONS
Ramping functions provide an automatic adjustment of the set point and
minimum ventilation fan speed over a given period of time.
CHOICE OF TEN MOTOR TYPES
The variation in motor speed resulting from a change in voltage will de-
pend on the make and capacity of the motor. In order to achieve a high
degree of compatibility between controller and motor, the user can choose
from among ten different motor types, thus ensuring that the correct volt-
age is supplied.
HIGH/LOW TEMPERATURE ALARM OUTPUT
HUMIDITY COMPENSATION
The stage 1 minimum speed can be adjusted automatically as a function
of relative humidity. As humidity increases, the minimum speed of stage
1 fans increases proportionally to compensate for the change.

ZONED OR CASCADING HEATERS
FULL-SPEED FAN START-UP
In order to overcome the inertia of the ventilation system components and
de-ice the fan blades in cold weather conditions, the controller supplies
maximum voltage to the variable speed fans during the 2 seconds imme-
diately following each start-up.
DE-ICING CYCLE
A de-icing cycle is provided for de-icing stage 2 variable-speed fans in
cold weather conditions.
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.
OUTSIDE TEMPERATURE COMPENSATION ON CURTAIN SPEED
Curtain opening and closing times can be decreased as a function of out-
side 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.
MEMORY CARD:
A memory card is used to create a copy of your controller's parameters.
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 OVATION 214 is used in combination with a DWR-F-1A controller,
the movement of the 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.
TEST MODE
A test mode allows you to simulate temperature changes and verify con-
troller performance.

INSTALLATION
Mounting Instructions
Open the latch and lift the cover. Remove the black caps located on
each of the four mounting holes. Mount the enclosure on the wall
using four screws. Be sure the electrical knockouts are at the bottom
of the enclosure in order to prevent water from entering the control-
ler. Insert the screws in the mounting holes and tighten. Fasten the
four black caps provided with the controller onto the four mounting
holes. The enclosure must be mounted in a location that will allow the
cover to be completely opened right up against the wall.
Connections
To connect the controller, refer to the wiring diagram enclosed with
this user's manual.
Set the voltage switch to the appropriate voltage.
Use the electrical knockouts provided at the bottom of the
enclosure. Do not make additional holes in the enclosure,
particularly on the side of the enclosure when using a com-
puter communications module.
It may be necessary to install a transformer in order to sup-
ply the appropriate voltage to the heating unit.
ALARM CONNECTION: There are two types of alarms on the mar-
ket. 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 NO terminal as shown on the wiring dia-
gram. For an alarm of the second type, use the NC terminal.

Motor Types
The relationship between the voltage supplied to a motor and its
operating speed is described by a motor curve. This curve varies
with the make and capacity of the motor. The various motors avail-
able in the industry have been divided into ten categories and the
controller has been programmed with a different motor curve for
each of these categories. To ensure that the controller supplies the
correct voltages, an appropriate curve must be selected for stage 1
and stage 2 according to the type of fan motors used.
1
Selecting a Motor Type for Stage 1 and Stage 2
Refer to the list of motors enclosed with this user's to choose the
proper motor type.
• Set the function to STAGE 1 MOTOR TYPE or to STAGE 2
MOTOR TYPE.The motor type of the selected stage is dis-
played, alternating with the letters "tYPE".
• Press the push-button once. The motor type flashes.
• Use the adjustment knob to adjust the motor type to the
desired value.
• Press the push-button once again to validate the new value.

Temperature Probes
1
Connecting the Probes
The controller is supplied with one temperature probe connected to
input # 1. Up to three additional 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.
• Use inputs # 2, 3 and 4 to connect additional probes, as
shown on the wiroing diagram enclosed.
CAUTION: Probes operate at low voltage and are isolated from the
supply. Be sure that probe cables remain isolated from all high volt-
age 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 a terminal or a ground.
Switches are used to activate or deactivate the additional probes
connected to the controller.
• Activate each additional probe by setting
the appropriate switch to ON:
- Switch # 3 activates the probe connected
to input # 2.
- Switch # 4 activates the probe connected
to input # 3.
- Switch # 5 activates the probe connected
to input # 4.
