Congratulations!

The SmartBox™incorporates the benefits from the most experienced manufacturer
of agricultural animal confinement building heating products using state-of-the-art
technology.

We,atL.B.White,thank you for your confidence in our products and
welcome any suggestions or comments you may have...call us, toll-free,
at 1-800-345-7200.

ATTENTION ALL USERS

The SmartBox™has been designed and developed by L.B.White Co. as a variable
rate heat controller for managing heat to demand within the animal confinement
facility. It works in conjuction with L.B.White Smart Sense™forced air and radiant
heaters and an existing room controller with on/off capability.

event of a power failure of more than 24 hours.

-- Enabling or disabling room sensors

-- Correlating the SmartBox

-- Setting the initial temperature set points for each

operates radiant heaters independently

■ 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.

-- 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.

the replacement controller

a. Use a thin bladed screw driver to evenly raise the

block from its alignment pins on the replacement
controller.

b.Insert the screwdriver blade no more than 1/8 in. to

prevent damage to the alignment pins.

c. Insert the screwdriver blade at one end of the

terminal block and rotate the blade about 1/4
turn.

d. Move to the other end of the terminal block and

do the same. See Fig.45. Repeat the process until
the block is evenly raised about 1/4 in. from the
alignment pins.

e. Once the block has been elevated, grasp the

block at its center and carefully pull the block
straight up.

f. Complete these same steps for removal of the

blocks with wiring from the original controller.

g. Remove respective blocks from replacement

-- Press straight down to firmly seat the
block.

-- Repeat the process for all blocks.

■ Troubleshooting this system may require operating the

unit with line voltage present. Use extreme caution

■ Failure to follow this warning may result in personal

injury or death.

PERSON.

Components should be replaced only after each step has
been completed.

The troubleshooting flow charts pertain to forced air, and
radiant heaters, (spark and manual ignition). Unless
otherwise noted, the troubleshooting is the same for all
heaters, regardless if forced air or radiant.

TEST EQUIPMENT REQUIRED

- for measuring AC and DC voltage and

resistance.

INITIAL PREPARATION

■ Check all internal wiring for loose connections and

worn/damaged insulation.

a. 120 VAC is supplied to SmartBox™.
b. Call for heat occurs from building controller.
c. Building controller closes heating contacts

enabling SmartBox
operation.

d. 120 VAC is sent to both transformers and to both

relays.

e. Upper transformer reduces 120 VAC to 24 VAC which

is sent to the programmable controller and radiant
heat signal conditioner.

-- Green LED on blinks 1 second ON, 1 second
Off (Normal operation)

f. Lower transformer reduces the 120 VAC to 24VAC

and sends it to the forced air signal conditioners.

g. Programmable controller sends 24 VAC to both

relays.

-- 24 VAC is used to close the relay coil.

-- Relays send out 120 VAC for power supply to
heaters.

h. Programmable controller sends out 4-20 mA signal to

the signal conditioners.

i. Signal conditioners use the 4-20 mA signal to change

the received 24VAC into 0-15 VDC output (forced air)
and 0-24 VDC (radiant).

-- Forced air signal conditioner sends the 0-15
VDC to the forced air heater’s variable rate
gas control

-- Radiant signal conditioner sends the 0-24
VDC to the proportional solenoid valve.
