INTRODUCTION
Thank you for buying a spa equipped with a SmarTouch
Digital control systems. Many years of experience went into
the design of this family of controls. You can be assured your
spa control system is the most advanced, it is highly reliable
and will serve you for many years to come.
The control system has been designed with the you the user
in mind. It is very easy to operate and requires a minimal effort
on your part. You may use it just as it comes to you and
without any programming. Yet you have the option of getting
deeply involved in the inner workings of the control if you so
choose. You can custom tailor it to fit your needs.
Please take the time to read at least the first section (next
page) “IN A HURRY - READ THIS” portion of the manual
before starting to use your spa for the first time. You can
familiarize yourself with the rest of the manual at your leisure.
This manual will also serve as a reference if you choose to
modify the operation of your spa.
SAVE THIS MANUAL.
Make it available for other spa users.
You should also have a spa user’s manual which explains
how to care for your spa. Please read and follow all
instructions in your spa user’s manual. Maintaining the proper
levels of pH and the sanitizer will extend the life of your spa
equipment. Improper chemical levels in the spa are sure to
cause premature heater failure as well as failure of other
components in the system. Failures caused by chemical
imbalance are not covered by warranty.

IN A HURRY - READ THIS
For those who don’t like to read manuals or would like to read the
manual later, please read at least the following section.
SmarTouch Digital comes to you with a universal set
of default settings. If you choose to keep these
settings, then you only need to remember 2 things :
how to set the spa temperature and to press the SET
key whenever you are done using the spa.
Setting Temperature
♦Pressand hold the TEMP key for 2 seconds. Release all keys
The display will flash the current selected temperature.
♦Using the TEMP and TIME keys (UP and DOWN arrows)
scroll to the desired temperature.
♦Press the SET key to lock in the new selection
The SET Key
After using the spa, press the SET key to tell the microcontroller you
are done using the spa. It will then take over the spa’s management
including the different filtration cycles, heat maintenance, economy
modes and protection against freezing.
Upon entering this mode the FILTER light is turned on and a post use
filtration cycle is executed - that is when the spa needs filtration the
most. The default system setting includes a 3 hour economy mode,
the pump will come on at most once every 3 hours to sample water
temperature and heat if necessary. The controller remembers when
you have used the spa and in anticipation of your next usage will
perform a 3 hour Auto Filtration cycle before your next spa use.
SmarTouch Digital Series 1000 and 2000 is a family of intelligent, spa
control systems. These systems are rich with features and can be
extensively programmed to fit just about any need. The rest of this
manual will explain the function of each of the keys on the control
panel, how to change programmed settings and what each setting
does. It will also explain all the error messages that you may
encounter, and their significance and way to correct them.
Page 5

Time Of Day (TOD)
SmarTouch Digital maintains a 12 hour AM / PM internal real time
clock TOD (Time Of Day). The clock based on the line frequency.
There is no battery backup and whenever the power is turned off,
TOD is no longer correct. It defaults to 12:00 AM whenever the power
is turned on.
Setting TOD is only necessary if you are going to program the filtration
and silence cycles. If you use the factory default settings then you do
not need to set TOD.
If you set TOD then SmarTouch will display time every first 10
seconds of each minute. If TOD has not been set then it will not be
displayed.
Setting TOD
1. Press and hold the TIME key for 2 seconds. Current TOD will
be displayed with the hour portion flashing.
2. Release the TIME key.
3. Using the TEMP and TIME keys scroll up and down to the
desired hour. - Notice the AM / PM Led.
4. When the correct hour and AM / PM are displayed press the
SET key to lock in the new hour.
5. The display will now flash the minutes portion of current TOD.
6. Using TIME and TEMP scroll to the desired minutes.
7. When the correct minutes are displayed press the SET key to
lock in the time of day (hours and minutes)
Note : TOD is the only parameter in SmarTouch Digital that is not
preserved on power down. On power up it will default to 12:00 AM, all
other parameters are restored to the their last setting.
Every time the controller is powered up, the microprocessor
automatically measures and determines whether the line frequency is
50 or 60 cycles in order to maintain the correct TOD.
Page 6

THE CONTROL PANEL
The control panel is normally installed on the lip of the spa for easy
and convenient access. Within the panel housing is a 4 digit LED
display used to communicate to the user spa temperature, TOD,
elapsed user time, programming, status - diagnostic and error codes
and messages. There are 2 different size panels. They are
interchangeable. the 2000 Series panel can have up to 7 keys, the
1000 Series panel will have at most 6 keys. These are membrane type
switches which when depressed generate a signal that the
microprocessor will interpret and act upon. The switches are labeled
and have specific functions. They are divided into 2 groups:
Device Control Group Pump(s), Air Blower & Spa Light.
Status Control Group: Up & Down Keys & the Set Key.
Note: if any of the keys is pressed and held closed for longer
than 20 seconds, that key will be disabled and becomes non
functional. After releasing the key, it will be reactivated after
20 seconds. This is to prevent a collapsed or defective key
from locking up the system.
DEVICE CONTROL KEYS
There are up to 4 device key, JETS, AIR, AUX & LITE. Your spa will
have at least one water pump. Optionally your spa may have an air
blower, a second and/or third pump and a spa light. It may also have a
mister or a fiber optic light setup. If your spa does not have a specific
device please disregard the function of that device.
Primary Water Pump
Each spa should have at least one primary water pump which is usually
a dual speed pump. The low speed is used to filter the spa. Also while
the spa is being heated or there is an error condition, the low speed
circulates the water and you will not be able to turn it off.
Page 7

The JETS key (switch) on the control panel is a 3 position switch :
Low Pump, High Pump, Off. Each time the key is pressed, the next
function is executed. If your primary pump is a single speed pump
then only the high pump will be activated. 2 LED indicators, LO & HI
inform you which speed is on.
Note : if your spa is equipped with a circulating pump it will
be used for filtration and heating instead of the low speed
pump.
Air Blower.
If your spa is equipped with an air blower (bubbler), it is activated by
the AIR key. This is an ON/OFF key. An LED will indicate when the air
blower is on.
Auxiliary Pump(s).
Your spa may be equipped with 1 or 2 more pumps. If you have a
second pump, it could be a single speed or a dual speed.
If you have a third pump then both the second and third pumps must be
single speed. The function of the AUX key changes with the number
and type of auxiliary pumps used. Please consult with the table on the
following page for the proper sequence of activation.
Spa Light
The LITE key can also be a multifunction key. In its simplest
configuration, the LITE key is a simple on / off switch. It turns the spa
light and the accessory, if one is attached, on / off together at the same
time. Alternatively the LITE key may be programmed as a 3 function
key. Pressing it once will turn the spa light on. Pressing it a second time
will turn on the attached accessory, while the light is still on. Press it a
third time and both spa light and accessory will go off.
The table on the following page summarizes all the possible device key
combinations. Please note that your spa may not necessarily have all
these devices attached.

Table 1 - Device keys summary of functions
The four device keys, JETS, AIR, AUX and LITE are exclusive, when
one is pressed, no other key may be pressed simultaneously. You
must release the pressed key before you may press another key. Also
these keys do not repeat.
If you press and hold a key for more than 20 seconds that key will be
considered defective (collapsed) and will be deactivated and ignored
by the system. When released the key will stay inactive for 20
seconds before it is recognized and activated.

STATUS CONTROL KEYS
The keys in this group are used to communicate to the controller
system settings and option selection(s). There are 3 keys in this group
and 3 functions that are combinations of these keys:
Key Press Function
TEMP (up arrow) Prog Temp, + or Next
TIME (down arrow) Prog TOD, - or Previous
SET key. Select or Accept , Enter
SET & TEMP Invert display
SET & TIME Parameter programming
TEMP & TIME System programming
Table 2 - Status Control Keys Summary
The TEMP key , which is also the UP ARROW key, is a repeat key if
held down. Think of this key as “+ or next”. Use it to :
♦Press and hold for 2 seconds then release it to start desired
temperature selection.
♦During temperature setting press TEMP to increase selected
temperature.
♦When doing system programming press TEMP to scroll to the
next message.
♦After message selection, the system displays the associated
value, press TEMP to increase that value.
Note: When the display is inverted, you will be able to read
the display from inside the spa ; the keys will retain their
functions and will not be inverted. The UP ARROW will still
function as the UP ARROW even though when you look at it
from within the spa it appears to be the DOWN ARROW.
The same also applies to the rest of the keys.
Page 10

The TIME key , which is also the DOWN ARROW key, is also a repeat
key. Think of it as “ - or previous”. Use it to :
♦Press and hold for 2 seconds then release it to start setting the
real time clock (TOD)
♦During time setting press TIME to decrease the hours or
minutes value that is being set.
♦When doing system programming press TIME to scroll to the
previous message
♦After selecting a message, the system displays the associated
value, press TIME to decrease that value.
The SET key is equivalent to Select or Accept. It functions as an Enter
key of a personal computer, it is the proverbial “hit any key to continue”.
Press the set key to:
♦After using the spa press the SET key to tell the controller to
take over the management of the spa.
♦During temperature setting press the SET key to lock in a
new selected temperature.
♦During time of day programming press the SET key to lock in
the hour and the minutes.
♦When a message is displayed during parameter
programming, press SET to select that message.
♦When a parameter value is displayed, press SET to accept
the displayed value and return to message display.
♦During option programming press SET to toggle a parameter
On or OFF.
♦When a “HLoH” error message is displayed press the SET
key to clear the error (if the the cause has been corrected).
Pressing the SET key, the user acknowledges that the
cause of the hi limit error has been or will be corrected.
Note: UP is synonymous with TEMP and DOWN is the same
key as TIME. These are used interchangeably and mean the
same thing. Scrolling means pushing either the UP or the
DOWN key to go to the next or previous item or value.
Page 11

PROGRAMMING SC1000 & SC2000
Parameter Programming is a means by which the spa owner /
user can change the various timing elements and calibrate
temperature. The process is simple and intuitive. Only 3 keys are used:
UP, DOWN and SET. To program one or more parameters follow the
outlined this procedure:
1.Press SET and DOWN keys together. The first message in the
menu, FP1 will be displayed.
2.Use the UP & DOWN keys to scroll thru the messages in the
menu.
3.Press the SET key to display the current value associated with
the current message.
4.Use UP or DOWN keys to increase or decrease the value.
5.Press SET to lock in the new value and return to the menu.
6.If another item needs programming go to number 2 above.
7.To save changes scroll to message SEND and press SET.
8.To discard changes and restore previous values scroll to
message CANC and press SET.
The menu of parameters is circular. Scrolling is from first to last or
from last to first.
When in programming mode please note that this mode will be
cancelled if there is no key activity for a period of 60 consecutive
seconds. Programming mode is aborted and all changes will be
restored to previous values.
On the following page is an example of how to program a filtration
period. When in programming mode you may program as many
parameters as needed.
Page 12

Example: program filtration period 2 to start at 5:45 PM
Press Display Explanation
SET & UP FP1 Start programming the display first message
is Filtration Period 1.
UP FP2 Scroll up to Filtration Period 2.
SET 12:00 Select FP2. The display shows the current
FP2 start time with the hour portion flashing

CALB 194 204 214 This is not a time element. It is one of the
distinctive features of the SC1000 and the
SC2000 systems. The number is internal
and is indicative of what the processor
sees as temperature. It is used to calibrate
the temperature reading. Increase this
value by 1 to decrease the displayed
temperature by ½ a degree. Decrease this
number by 1 to increase displayed
temperature by ½ a degree. For example if
the controller is displaying a temperature 2
degrees lower than real temperature,
increase the number by 4 to get a correct
reading. The total range of this parameter
is 10 degrees Fahrenheit. Before doing a
calibration Please read warning note at
end of this page.
SEND This menu message has no numerical
value. Pressing SET while it is displayed
records and saves all changes made to all
parameters.
CANC This menu message also has no value.
Pressing SET while it is displayed discards
all changes made to all parameters and
restores last saved or previous values.
WARNING
The recommended maximum temperature of a spa is
104°F. The absolute maximum beyond which no
person should ever be exposed to is 108°F. When you
calibrate the spa temperature you are doing so at your
own risk. Obtain an accurate medical thermometer to
check against. Please contact ACC for proper
procedure or if you do not feel confident.

PROGRAMMING SYSTEM OPTIONS
System Options Programming is a means of setting the
various system options. The U and P options are of the ON / OFF or 1
/ 0 type; the option is either 1 or ON or it is a 0 or OFF. The D options
can only be displayed. They may not be changed by the user. To
initiate options programming press the UP and DOWN arrows
together. There are 3 groups of 8 options each :
User options U1 to U8
Protected options P1 to P8
Diagnostics D1 to D8
When programming groups 1 and 2, (U and P options) either the letter
U or the letter P is displayed followed by a number (1 to 8), a space
and the number 1 if the option was ON or a 0 if the option was OFF.
For example if the third user option was OFF the letters U3 0 will be
displayed. If it was ON the display will read U3 1.
Use the scroll buttons (UP and DOWN) to navigate thru the different
options. Press the SET key to toggle a displayed option's status from
0 to 1 or vice versa. Go to SEND and press SET to save changes.
Alternatively go to CANC and press SET to discard all changes and
restore previous settings.
The Diagnostics are not options, but rather they display internal
values that are indicative of the internal state of the processor. They
are useful for a serviceman or a technician and to pinpoint hardware
problems and error conditions.
The following tables list the User Options and the Protected Options
and their significance when they are ON and OFF.
User Options
U1 0 = Economy mode is on. In this mode water temperature is
sampled every 3 hours or whatever ECL is set to. If the spa
is being used the economy mode is off.
1 = Auto Maintenance is on, temperature is sampled and
acted upon continuously.
Page 17

U2 0 = Low pump on demand. The low pump will come on to
sample temperature, heat or filter the spa as needed.
1 = The low pump runs all the time.
U3 0 = Auto Filtration is one 3 hour long period. This length of this
period is fixed and cannot be changed. It is the minimum
recommended filtration time for a spa.
1 = Auto Filtration is two periods each 3 hours long. The
second period starts 12 hours after the first period is
executed.
U4 0 = User timer starts with the first key pressed and shuts the
spa off at the end of count down.
1 = The user timer is restarted every time a key is pressed.
U5 0 = Display TOD, time of day the first 10 seconds of every
minute, if the time of day has been set.
1 = Do not display TOD. If TOD was not set by the user then it
most probably is incorrect and the controller will not display
it even if U5 is a 0.
U6 0 = If line frequency is 60 hz, then display temperature in
Fahrenheit. If 50 hz then display Centigrade.
1 = If line frequency is 60 hz, then display Centigrade. If 50 hz
then display Fahrenheit.
Note : Line frequency is automatically measured by the
microprocessor every time on power up.and the displayed
temperature will follow the frequency : Fahrenheit for 60Hz
(US), Centigrade for 50Hz (Europe). When option U6 is set
ON, the units of displayed temperature will be opposite to the
frequency.
U7 RESERVED do not change leave it at 0
U8 RESERVED do not change leave it at 0
The default setting for all U options is 0.
Page 18

Protected Options
Warning : Changing any of the Protected options may
be dangerous and can result in injury. It can also
damage the spa and it's equipment as well. Changes
made by user are at the his/her own risk. All liability
rests with the person doing the changes. Only trained
service personnel should make changes. If unsure
please contact ACC for more information.
P1 0 = There is no additional circulating pump. The primary
pump is usually 2 speed. The low speed is the filtering
and heating pump
1 = A circulating pump is attached to the system.
P2 0 = The primary pump is a 2 speed pump.
1 = The primary pump is a single speed pump.
Note : The circulating pump is always attached thru the
heater. All filtration and heating is done with the
circulating pump when one is attached to the system.
P3 0 = The system has high amps available.
1 = The system is only capable of 20 or 30 amps, (low power).
In this mode the heater can only operate with the low or
circulation pump. It is disabled with all other selections.
P4 0 = The LITE key operates as an On/Off switch. The light relay
and the accessory relay (if installed) operate together.
1 = The LITE key is a 3 function key:
♦Press once, the spa light is turned on
♦Press again, both spa light on and accessory go on
♦Press a third itme for both functions to go off
P5 0 = Reserved. Do not use this option.
P6 0 = Air blower is enabled. The AIR key is active.
1 = Air blower is disabled. The AIR key is deactivated.
Page 19

P7 0 = Secondary pump is a single speed pump.
1 = Secondary pump is a dual speed pump.
P8 0 = There is only one secondary pump.
1 = There are 2 secondary pumps.
Note : if P8 is ON, then by definition both secondary
pumps must be single speed.
Warning : an improper setting of P7 and P8 can
result in damaged or even destroyed pump motors.
It can also cause the controller's printed circuit
board to catch fire. Only trained service personnel
should carry out changes.If unsure please contact
ACC for more information.
