and described in separate appendixes. Except for a few functions dealing with scales, Pig
Mode supports the vast majority of functions seen in Broiler Mode. Pig Mode has some
different terminology (for example herd instead of flocks).
This screen sets the temperature targets according to the bird age.
1. In System > Sensors > Analog, designate the required number of sensors as temperature sensors.
When using more than one sensor, Platinum Touch/Rotem One Touch begins treatments based on
the average.
2. In System > Temperature Definition, assign specific sensors to devices. If a zone does not have
an assigned sensors, calculations are based on the current average temperature.
3. In Control > Temperature Curve, define the required target temperature curve.
o
Set up to 20 lines, 999 growth days. When a curve is not required (for example when

at the Heat Temperature.
NOTE Heaters operate at minimum level only; however, Radiant Heaters can operate at any
temperature or level below Tunnel.
o
Cool Down Factor (%): Minimum percentage correction towards target during each
increase ventilation level delay. If average temperature does not decrease by this
amount, the Platinum Touch/Rotem One Touch increases ventilation by one level.
o
Cool Down Fast Response (Deg.): Set a limit to the maximum degrees per minute of
cooling. If Average Temperature drops more than this in one minute, Platinum
Touch/Rotem One Touch decreases ventilation one level to avoid overshooting.
NOTE Avoid making this parameter too small or the normal temperature variation caused by timer
fans reduces the ventilation level.
o
Minimum Ventilation Below Heat Temp: Tells controller to go directly to minimum level
in some cases. Select from the following choices:
•
None: Operate by the normal level decrease time delay rule.
•
Zone: Go directly to minimum level if any active temperature sensor reaches heat
temperature.
•
Avg.: Go directly to minimum level if the average temperature reaches heat
temperature.
Non Brood Area Diff. From Heat: Set differential temperature for non-brood
heaters. You normally use this to set temperatures in unoccupied areas (poultry modes
only).
NOTE When set at -99° F the heaters are effectively disabled, since it will probably never go to 99º F
below the heater temperature. Putting this parameter at 0º sets the non-brood areas to the
heater temperature.
3.1.2 C
YCLE HEATERS HELP | SET DEFINITIONS
Heat Cycle means providing heat in conjunction with the ventilation system during minimum ventilation
cycles, using heaters and fans connected to relays. When enabled, heaters operate during the fans’
cycle off time (as defined in the Cycle Heaters Help | Set Definitions parameters). How does it work?
Between the Heat Temperature and the differential temperature, heaters do not operate. When the
temperature goes below the Heat Off temperature minus the Low Heat Differential:
•
Heaters begin to operate when the exhaust or tunnel fans are off. Heaters operate for the
Minimum On Time.
•
If the temperature continues to drop, heaters operate for longer periods of time, up to the
Maximum On Time (defined in Levels of Ventilation).
•
Platinum Touch/Rotem One Touch automatically generates a curve.
1. Define the required number of heater and exhaust and/or tunnel relays (Relay Layout, page 94).
2. In Control > Control Mode, set the Heater Cycle to Yes.
3. In Control > Temperature Curve > Help, scroll to Cycle Heater.
4. Define:
o
Low Heat Differential: The differential below the Heat Off temperature, at which heating
begins and runs for the minimum amount of time.
o
High Heat Differential: The differential below the Heat Off temperature, at which heating
runs for the maximum amount of time.
o
Minimum ON Time: Minimum heating time when the exhaust or tunnel fans are off.
3.1.3 R
To configure the radiant heaters:
ADIANT HEATERS HELP | SET DEFINITIONS
1. In System > Relay Layout define at least one relay as a radiant heater.
2. Define:
o
Radiant Low – Differential from Heat Set: Set degree of difference from Heat for LOW
Radiant Heaters to begin working. This differential can be positive or negative. (default:
2.0)
o
Radiant High – Differential (Below Low Set): Set number of degrees below Radiant
Low Heaters for HIGH Radiant Heaters to begin working (default: 1.0). To ensure
proper heater ignition, Radiant High Heaters remain on for the Radiant Ignition Time
along with the Radiant Low Heaters.
Radiant Ignition Time (sec): Set number of seconds to power radiant ignition (default:
30).
NOTE The Heater Temperature Band applies to radiant heaters as well. For example, if the Heat
Temperature is 80º F and the Heater Temperature Band is 1º F, then heaters turn on at 79º F
and off at 80º F. If the Radiant Low Differential is at 2.0º F, than radiant heaters turn off at
82º F, and on 1º F below that at 81º F. However, a Radiant High Heater turns on regardless
of its temperature setting for the Radiant Ignition Time whenever the corresponding Radiant
Low Heater turns on. This feature ensures proper flame ignition.

The Platinum Touch/Rotem One Touch enables configuring up to eight variable heaters. The output of the
heaters changes as the temperature increases or decreases.
ARIABLE HEATER HELP | SET DEFINITIONS
Install at least one analog output card.
To configure the variable heaters:
1. In System > Analog Outputconfigure:
a. up to eight analog outputs as variable heaters.
b. the minimum and maximum voltage output for each heater.
2. In Control > Control Mode, define the Analog Heat Mode:
o
Linear Heat
o
Proportional Heat
o
Linear Valve
3. In Control > Temperature Curve, click and scroll to Variable Heater.
Between the Heat Temperature and the Target temperature, heaters do not operate (meaning,
the output voltage is 0).
•
Between the Heat Temperature and the Low Difference Below Heat, heaters operate at the
minimum voltage output.
•
If the temperature continues to drop, the voltage output increases until it reaches the maximum
voltage output at the High Difference below Heat.
In this example:
•
Target Temperature is 80°
•
Temperature Curve Heat Off is 78°.
•
Low Heat Differential is 1°.
•
High Heat Differential is 8°.
o
If the temperature is between 77° to 78°, the output voltage is the minimum voltage
defined in Installation > Analog Output (1 volt in this example).
o
If the temperature continues to drop, the output voltage increases until it reaches the
maximum voltage defined in Installation > Analog Output. Output increases or
decreases to keep the temperature within the Target Temperature and Heat Off band.
Figure 4: Linear Heat Curve
•
Define:
o
Low Difference Below Heat: Temperature difference between the Heat Off parameter
at which the variable heater begins to function.
o
High Difference Below Heat: Temperature at which the heater begins to operate at
maximum output.
3.1.4.2 Proportional Heat
Proportional Heat works in manner similar to Linear Mode. The difference is that Proportional Heat
features a delay time.
When the temperature falls below the user-defined point, the heaters begin operating at their
minimum output.
•
After the response time passes, Platinum Touch/Rotem One Touch checks the temperature. If it
is still below the defined point, Platinum Touch/Rotem One Touch increases the voltage by a
certain amount (this amount of the increase cannot be changed).
•
After the response time passes, the process is repeated until heaters operate at their maximum
output.
•
Define the parameters.
o
Difference Above Heat to Stop Heater: Differential from target temperature at which
the heater runs at minimal input.
o
High Difference Below Heat: High Difference Below Heat: Temperature at which the
heater begins to operate at maximum output.
o
Response Time (seconds): Amount of time before the controller begins to change the
ventilation.
3.1.4.3 Linear Valve
Linear Valve enables defining that variable heater input voltage is always equal to or above the minimum
input defined in Installation > Analog Sensors.
When the Analog Heat Mode is defined as having Linear Valve control, there is always a minimal
voltage input. Therefore, if the minimum voltage is 1 volts:
•
The voltage range is from 1 to 10 volts
o
this corresponds to 10% at 1V and 100% at 10V
o
interpolation inside the band
•
There is 0% voltage when the target temperature is reached.

•
Define:
o
Difference Above Heat to Stop Heater: Differential from target temperature at which
the heater runs at minimal input
o
High Difference Below Heat: High Difference Below Heat: Temperature at which the
IMPORTANT: Before setting Min/Max level, go through and set up the Device Settings,
especially the ventilation levels.
Once you have entered the ventilation levels, use the Min/Max to select the range of levels to apply to
your situation. Typically, Platinum Touch/Rotem One Touch increases the minimum ventilation level as
litter conditions deteriorate and the birds require greater amounts of fresh air. You can also restrict the
maximum level to prevent excess airflow on young birds.

temperature.
o
Minimum Level: Set the minimum ventilation level for when temperature is above heat
temperature.
o
Maximum Level: Set the maximum ventilation level for controller.
2. If required, click and set the parameters.
3.2.3.1 Soft Min/Max Level Help | Set Definitions
•
Define:
o
Difference Below Heat for Soft Minimum: Set the degree of difference from the heat
temperature (set in Temperature Curve) to switch the minimum level from Min. to Soft
Min.
o
Temp Choice for Soft Minimum: Select inside/outside/attic temperature to control
Minimum Level changes. The minimum level adjusts towards the Soft Min as this
temperature falls. Above the heat temperature, the minimum level is at the Min setting.
As temperature rises, INSIDE and ATTIC stay at lowest ventilation level reached until average
temperature gets to the heat setting, and then changes instantly. With the OUTSIDE selection, the
minimum ventilation level increases gradually as temperature rises to the heat setting. This means inside
and attic soft min vent choices to latch to the lowest level reached as long as the temperature remains
below the heat setting.
3.2.4 BY W
EIGHT
The By Weight option enables controlling the minimum air flow depending on the number of birds, their
weight and the current outside temperature. When using the Weight option, Platinum Touch/Rotem One
Touch takes several parameters and calculates the air speed, level of ventilation and cycle time needed to
supply the required volume. As opposed to the other ventilation methods, the Weight option is dynamic,
with the ventilation changing according to the current parameters (quantity of air required, weight of birds
and number of birds, outside air temperature). In addition, Ventilation By Weight sends out an alarm if
the current ventilation is below the minimum required level.
To set up the Weight Option:
1. In System > Setup, enable Minimum Ventilation.
2. In System > Temp Definition, define at least one temperature sensor as Outside.
3. In System > Fan Air Capacity, define the air capacity / hour.
4. In System > Scale Setting> General, select the curve.
5. In System > Bird Curve, define the growth days and weights as required.
3.2.4.1 Minimum/Maximum By Weight Help | Set Definitions
•
Define:
o
Warm Temperature – Difference Below Heat: Differential below the heat temperature
(refer to Temperature Curve) that defines outside temperature as Warm in the Soft
Min/Max table. For example, if the Heat Temperature is 78° F, Warm Temp. – Diff
Below Heat is 2.0, than the outside temperature is defined as warm at 76° F.
o
Cold Temperature: Outside temperature (or below) at which Air per Kg/Lb. (Cold)
capacity is reached.
NOTE When the outside temperature is between the Warm and Cold Temperature, the flow rate is
calculated at a proportional rate.
o
Air Change: As the temperature rises from the Cold Temperature parameter to the Heat
Temperature (or drops from the Heat Temperature to the Cold Temperature parameter),
the minimal air volume rises/falls proportionally. Air Change defines the minimal change
in air temperature that must takes place to cause a change in the air supply.
o
Fan Cycle Time: The total amount of time that the fans operate while operating under
Minimum Ventilation. During this time, the fans supply the required volume of air at the
minimum ventilation level required. Platinum Touch/Rotem One Touch adjusts the
minimum ON time and OFF time as needed. If the fans cannot supply the required
volume at a particular level of ventilation, Platinum Touch/Rotem One Touch
automatically adjusts the minimum ventilation level.
o
Minimum ON Time in Vent Cycle: The minimum amount of time that the fans operate
during a ventilation cycle. Platinum Touch/Rotem One Touch adjusts the actual fan time
as needed.
o
Minimum OFF Time in Vent Cycle: The minimum amount of time that the fans do not
operate during a ventilation cycle. Platinum Touch/Rotem One Touch adjusts the actual
fan time as needed.
As the temperature rises, the actual Minimum OFF Time decreases until it reaches the minimum time;
only then does the Minimum On Time begin to rise.
NOTE If the temperature goes above the Band Temperature, Power Ventilation begins and times are
adjusted accordingly.
o
Air Change By Humidity/CO2%: As the humidity/CO2 levels rise above the levels
specified in Humidity Treatment and CO2 Treatment, the minimal air volume rises
proportionally. Air Change By Humidity/CO2% defines the minimal change in these
levels that must take place to cause an increase in the air supply.
o
Air Per Weight Curve Mode: By default, Air per Kilo/Lb. has two data points: cold
temperature and warm. If desired, the user can add an additional intermediate data
point which is between the two default points. This point determines the quantity of air to
be distributed when the temperature reaches the midpoint between the cold and warm
temperatures.
3.3 Introduction to Humidity, Ammonia, and CO2 Treatment
Platinum Touch/Rotem One Touch provides various options to controlling the humidity, CO2, and
ammonia levels.
•
None: No treatment is provided.
•
Level: Ventilation levels increase for a designated amount of time.
•
Tunnel or exhaust fan: A designated fan turns on for a designated amount of time. The amount of
air blown into the house is greater than that provided by an increase in ventilation level.
•
Increase in air / weight: The total amount of air that fans need to provide increases by a user
defined amount. Fan stay on until CO2, humidity, or humidity levels fall to their defined levels.
This option is only available when using Minimum Ventilation by Weight.
•
Humidity treatment by heat: In cold air situations, heaters can be turned on to lower the relative
humidity.
If there is a contradiction between CO2, humidity, and ammonia treatments:
• Ammonia treatment has priority over CO2 treatment.
• C02 treatment has priority over humidity treatment.
• Increase in air / weight has priority over other treatments.
• Humidity treatment by heat takes priority over increasing the ventilation.
3.4 Humidity Treatment
Humidity treatment forces an increase in ventilation level when the humidity is too high. It holds the
increase for ‘Duration Seconds’, and checks back after ‘Interval Minutes’ for another increase. After the
duration, the ventilation level comes back down automatically.
1. In System > Sensors > Analog, designate one or two sensors as indoor humidity sensors (outdoor
sensor is for information only). When using more than one sensor, Platinum Touch/Rotem One
Touch begins treatments based on the average.
2. In Control > Humidity Treatment define:
o
Day: Set the growth day. You can set multiple programs for same day (maximum number
of programs: 20)
o
Humidity: Set the humidity level at which to begin treatment.
o
Delay (Min): Set the amount of time the controller pauses before ventilating.
o
Duration (Sec): Set the number of seconds the controller maintains the increased level of
ventilation
3. Set the Humidity Sensor Alarm.
4. If required, click and set the parameters.

Humidity Band (%): Set the differential band for Humidity Treatment. For example, if the
humidity target is 75% and the band is 2%, treatment begins at 77%.
o
Humidity Treatment below Heat: Select YES or NO for allowing Humidity Treatment
when heaters are operating (set in Temperature Curve).
o
Humidity Treatment By: This parameter designates the method used when humidity or
CO2 treatment begins. Normally, this parameter is relevant only when minimum
ventilation is running. When a treatment is required, select the method to be employed:
•
None: Disables the treatment.
•
Level: Increases the ventilation level when a treatment is required.
NOTE When employing Ventilation by Weight, the controller increases the cycle time or the level,
Humidity Treatment by Heaters: This parameter enables using the heaters to lower the
relative humidity. If enabled, define:
•
Outside Temp Treat by Heaters: A differential from the target temperature; when the
outside temperature reaches this point, heaters turn on and remain on for the duration
time.
•
Diff to Stop Treatment by Heaters: A differential from the target temperature; when the
inside temperature reaches this point, heaters turns off and remain off for at least the
duration time. This number can be positive or negative.
Humidity Treatment by Heater requires designating at least one thermometer as an outside
thermometer (refer to Temperature Definition, page 99).
NOTE If the heaters are operating because of the interior temperature, Humidity Treatment by Heater
is disabled.
NOTE Broiler and Breeder Modes support Humidity Treatment by Heaters.
3.5 CO2 Treatment
CO2 treatment forces an increase in ventilation level when the CO2 level is too high. It holds the increase
for ‘Delay Seconds’, and checks back after ‘Interval Minutes’ for another increase. After the duration, the
ventilation level may come back down automatically. If during treatment, the CO2 level drops below the
Stop Value parameter, the ventilation level automatically returns to that level used before CO2 treatment
was initiated.
1. In System > Sensors > Analog, designate one sensor as a CO2 sensor.
2. In Control > CO2 Treatment define:
o
Day: Growth day. You can set multiple programs for same day (maximum number of
programs: 20)
o
Start Value: CO2 value at which to begin treatment
o
Stop Value: CO2 value at which to end treatment
o
Delay: Number of seconds the controller pauses before ventilating
Duration: Number of seconds the controller maintains the increased level of ventilation
3. Set the CO2 Sensor Alarm.

•
Define:
o
CO2 Treatment below Heat: Select YES or NO to enable CO2 treatment when heaters
are operating (set in Temperature Curve).
o
CO2 Treatment By: This parameter designates the method used when humidity or CO2
treatment begins. Normally, this parameter is relevant only when minimum ventilation is
running. When a treatment is required, select one the method to be employed:
•
None: Disables the treatment.
•
Level: Increases the ventilation level when a treatment is required.
NOTE When employing Ventilation by Weight, the controller increases the cycle time or the level,
depending on the particular settings.
o
CO2 Treatment by Heaters:
CO2 Treatment by Heater: This parameter enables running the heaters in situations where the
CO2 level is high. Typically this can happen in cold temperatures when CO2 is produced by
the heaters. By increasing the heat in the house, ventilation can then be increased. If
enabled, define:
•
Outside Temp Treat by Heaters: A differential from the target temperature; when the
outside temperature reaches this point, heaters turn on and remain on for the duration
time.
•
Diff to Stop Treatment by Heaters: A differential from the target temperature; when the
inside temperature reaches this point, heaters turns off and remain off for at least the
duration time. This number can be positive or negative.
CO2 Treatment by Heater requires designating at least one thermometer as an outside
thermometer (refer to Temperature Definition, page 99).
NOTE If the heaters are operating because of the interior temperature only, CO2 Treatment by
Heater is disabled.
3.6 Natural Ventilation
Natural Ventilation enables supplying the house's air requirements using the wind. Using the Natural
Ventilation depends on a variety of environmental and scheduling factors. While in this mode, curtains
open and close based on the target temperature.

OW DOES NATURAL VENTILATION WORK
For Platinum Touch/Rotem One Touch to switch to Natural Ventilation:
•
Natural Ventilation works only during the defined growth days and daily schedule.
•
The temperature inside the chicken house must be within the inside temperature band.
•
The temperature outside the chicken house must be within the outside temperature band.
•
If the temperature is below either of the above two parameters, ventilation switches to Minimum.
•
If the temperature is above either of the above two parameters, ventilation switches to Tunnel
(there is an option to remain in natural ventilation; refer to Minimum Wind Speed for Tunnel
Temp).
•
The wind speed must be within the wind speed band.
•
The wind direction must be within the user-defined area.
NOTE Including the wind speed and direction in Natural Ventilation calculations is optional and
requires in the installation and configuration of additional equipment.
•
If the weather conditions meet the above requirements, curtains open to a calculated position
based on the difference temperature and minimum and maximum percentage. If more air is
required, the curtains adjust themselves automatically using a calculation based on the minimum
and maximum curtain position. The larger the difference between the minimum and maximum
openings, the larger the step.
•
Any change in the curtain position takes place after the Delay Time.
