Inst ll tion
1. Drill five 0.187” holes in customer supplied b ck pl te using
stick on templ te supplied with control. St nd rd st ndoffs
re designed for b ck pl te thickness of 0.062 (1/16").
St ndoffs re v il ble for b ck pl tes of 0.125 (1/8") nomi-
n l thickness. If retrofit pl te st ndoffs re used, drill 5
(five) 0.250 di . Holes in proper loc tions.
2. Inst ll five st ndoffs into b ck pl te. Inst ll two support st nd-
offs into circuit bo rd. CAUTION: Be c reful not to bend or flex
the circuit bo rd during inst ll tion s this c n d m ge the con-
trol. Do not push down on tr nsformer or rel ys during inst ll -
tion. Inst ll circuit bo rd onto st ndoffs by gently pushing down
on circuit bo rd t bo rd edges ne r st ndoff loc tions until
bo rd is fully se ted. See sketch for proper inst ll tion. Inst ll
control in ppropri te enclosure.
3. Wire controls per wiring di gr m, following N.E.C. nd loc l
codes. Use ppropri tely sized sp de termin ls.

Operation
DIRECT MODE BOTH FUNCTIONS
AUTOMATIC RESET (Reset Switch terminals not wire ) When the
liqui rises to the electro e on terminal LLCO, the control energizes,
changing state of the loa contacts. (LED will be lit) The control re-
mains energize until the liqui level rece es below electro e on
terminal LLCO. The control then e-energizes, (LED will not be lit)
returning loa contacts to original state. Unless otherwise specifie ,
there is a three secon time elay on ecreasing level. Liqui must
be below probe on terminal LLCO for a full three secon s before con-
trol e-energizes.
MANUAL RESET (Normally close pushbutton installe across reset
terminals) When the liqui rises to the electro e on terminal LLCO,
the control will remain e-energize until the pushbutton is e-
presse . Upon Reset Swtich activation, the control will energize,
(LED will be lit) changing the state of the contacts. The control re-
mains energize until the liqui level rece es below electro e on
terminal LLCO. The control then e-energizes, (LED will not be lit)
returning loa contacts to their original state. Unless otherwise spec-
ifie , there is a three secon time elay on ecreasing level. Liqui
must be below probe on terminal LLCO for full three secon s before
control e-energizes. Operator to wait 5 full secon s after power is
applie before pressing reset switch (if manual reset is use ).
H-L Function: When the liqui rises to the electro e on terminal H,
the associate relay energizes, changing the state of the loa con-
tacts. (LED will be lit). The relay remains energize until the liqui
level rece es below electro e on terminal L. The associate relay
then e-energizes, (LED will not be lit) returning loa contacts to
original state. Unless otherwise specifie , there is a one half secon
time elay on increasing level. Liqui must be in contact with probe
on terminal H for a full half-
second before control energizes. This function c n be wired for
single level service by using only the H termin l.
INVERSE MODE
LLCO Function: LLCO lw ys functions in direct mode only see
bove for oper tion.
H-L Function: Associ ted rel y energizes with power, (LED will be
lit) ch nging the st te of the lo d cont cts. When the liquid rises to
the electrode on termin l H, the rel y de-energizes, returning lo d
cont cts to shelf st te. (LED will not be lit). The ssoci ted rel y
rem ins de-energized until the liquid level recedes below electrode
on termin l L. The rel y then energizes.
TEST FEATURE
Allows LLCO circuit to be tested without the need to drop the w ter
level in the boiler to cre te dry probe condition. Holding down the
reset button for 3 seconds will llow the LLCO circuit to trip, simul t-
ing dry probe. The controller will return to norm l oper tion once
the reset button is pressed second time.
LED St tus Indic tor In norm l oper tion, the LED on the control
will either be on or off depending on the controller st te. On-bo rd
microprocessors continuously monitor for f ult conditions. In the
event f ult is detected, the LED will blink p ttern indic ting the
f ult type. If you experience n inoper ble control nd the LED is
blinking, ttempt to le ve the control in the blinking st te nd con-
t ct the f ctory for ssist nce.
Options
M nu l Reset with option l Power Out ge Fe ture: The Power
Out ge option, used in conjunction with the M nu l Reset option,
elimin tes the need for m nu l reset in the event of power out-
ge during norm l boiler oper tion. With the Power Out ge option, if
there is loss of power with liquid present on the LLCO probe, the
control will self-reset (energize) IF liquid is still present on the LLCO
probe t the time when power is re-est blished. If the control did not
h ve liquid on the LLCO probe t the time of the power out ge, or if
there is no liquid present t the time power is re-est blished, the
control will de-energize nd rem in so until liquid g in rises to the
LLCO probe nd the M nu l Reset pushbutton is depressed.
Time Del ys ssoci ted with termin ls H nd L : With time del y on
incre sing level, the liquid must be in cont ct with the high electrode
for the full dur tion of the time del y before control will oper te. With
del y on decre sing level, the liquid must be below the low elec-
trode for the full dur tion of the time del y before control will oper-
te.
Time Del ys ssoci ted with termin l LLCO: 3 Second time del y
on decre sing level is st nd rd.
