Set Up and Programming
TOUCH PAD CONTROL AND DISPLAY
The touch pad control is an interface device used to
program and operate the control. There are two touch
pad controls. Either can be programmed to operate
d i f fe r e n t ro o m s a t d i f fe r e n t te mp e r a t u r e s a n d
schedules. Set-up for the touch pads is the same. See
Fig. 13 as an example.
FIG. 13
■
The following can be programmed from the touch pad:
-- Setting for manual operation.
-- Setting the clock at initial start-up or resetting in the
event of a power failure of more than 24 hours.
-- Enabling or disabling room sensors
-- Correlating the SmartBox
™
sensors to room
controller sensors
-- Setting the initial temperature set points for each
zone.
-- Setting the initial temperature curve, if one is used.
-- With the system in operation, temperature and day
points can be edited to make changes as needed.
■
There are up and down keys to adjust parameters.
■
There are three soft keys used to access and program
entries:
-- Designation for the function of each soft key is
indicated at the bottom of the display screen
within the three boxes. Designations change
depending on operating mode.
BASIC ROOM CONTROL-TYPICAL SET-UP
■
The SmartBox
™
inter faces with an existing room
controller that has an on/off heat control in order to
provide variable rate heating.
■
There is a desired room air temperature -not to be
exceeded- typically called:
-- DRT (Daily Required Temperature) or
-- Set Point
■
The typical swine room control will operate a minimum
ventilation fan plus additional stages of ventilation.
-- If DRT /Set Point is exceeded by room temperature
the ventilation fan will increase in speed to full
output.
-- At some point, if this increased airflow is not
sufficient to cool the room back to the desired
DRT/Set Point, then additional stages of
ventilation are activated.
■
To avoid the situation of heaters causing room air
temperature to increase above the DRT/Set Point
thereby causing increased ventilation to remove the
heated air, the settings for heat “on” and “off” are set
to avoid overshoot and the accompanying waste of fuel.
As an Example:
-- DRT/Set Point is 82 F
-- Heater “on” offset is -3F: heater comes on at 79F.
-- Heater “off” differential is -1F, the heater goes off at
81F. This is below the DRT/set point and intended to
minimize overshoot.
With settings given such as in the previous example:
-- You will typically see 5-6 degrees variation in room
temperature. This variation will be eliminated with
variable heat control.
-- The actual average room temperature due to heating
is about 2F lower than the stated DRT/Set-point
temperature, in this example 80F.
Note: The actual average room temperature is what will
become the Set-point for the variable rate
heating.
TEMPERATURE CONTROL PARAMETERS
■
There are two ways of utilizing the temperature control:
A. Manual Mode: Temperature is adjusted as needed by
the operator based on appearance and performance of
the animal. Note: To operate in the manual mode, the
room controller temperature set point and the
SmartBox
™
temperature set point must be aligned.
B. Temperature Curve: there is a defined temperature
c u r ve o f te mp e r a t u r e v s . d ay s t h a t i s u s e d to
automatically adjust the room temperature environment
as the animal ages.
