Make it available or other spa users.
You should also have a spa user’s manual which ex-
plains 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 cov-
ered by warranty.
NO Check for the following:
1- Voltage at the Heater Contactor Coil Relay. Across the White and Yellow wires. 120V or 240V depending on
power rating on contactor relay.
If power is present and contactor does not engage, replace contactor.
If there is no power replace PCBoard
2- Check power at load / output (right) side of contactor . If there is power go to next step. If not go back to step one.
3- Check power at Heater L M NT. If no power then High Limit relay on PCBoard is NOT -- closing. Remove plastic
dust cover off and inspect relay contacts. Replace PCBoard.
OVERHEAT ERROR CODES ( OH or HLEr) but spa water temperature is not.
Allow enough time for the sensors to cool down. Then clear the error code by pressing the S T button.
1-Turn temperature down to lowest setting & press the S T key
2- Press S T a second time and allow the low speed Jets to run for 2-3 minutes
3-Is temperature reading dropping? Does it match the thermometer reading in the spa ?
4-If Y S . there is flow restriction. Clean / inspect or remove filter cartridge. Or secondary bypass intake to the pump is
blocked or not installed.
5-Raise the temperature setting to 4 degrees above water temperature. Average heat gain is about 30 minutes. If there is
rapid heat gain go back to step #4.
QRC- 215A
Micro-processor technology is becoming a familiar name in the spa in-
dustry. Here, at Applied Computer Controls, we produced our first intelli-
gent microprocessor based spa control system, in 1981-82. The SC-100
and SC-200; the forerunners of intelligent electronic spa controls.
Today, SmarTouch Digital includes more than 30 years experience.
SmarTouch Digital, is a fourth generation microprocessor-based control
system. A reliable energy efficient spa controller, so advanced but easy
to operate, is conveniently located at your fingertips. A high intensity,
oversized characters, L D display or our multi colored LCD display, keeps
you informed of the spa temperature, time-of-day and elapsed time and
a list of error codes, to inform and identify a malfunction.
Safety and reliability are built-in to meet or exceed the most stringent,
up to date requirements set by (UL) Underwriters Laboratories.
SmarTouch Digital is the culmination of proven designs and extensive
testing… from Applied Computer Controls.

INTRODUCTION
Thank you for buying a spa equipped with a SmarTouch Digital con-
trol system. 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 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 work-
ings 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 – R AD 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.
The more e icient the system is the
less energy it uses.
The concept behind SmarTouch Digital is to maintain the desired
temperature setting and water filtration with the least amount of en-
ergy consumption.
Temperature and Overheat sensors are located at the Stainless Steel
heater manifold, the coldest and hottest spot where true tempera-
ture is measured and to detect Freeze and Overheat conditions.
Considering the large volume of cooler water in the plumbing, pump
and heater manifold, low speed primary pump is activated for five
minutes every three hours to stabilize spa temperature, prior to ac-
tivating the heater. stimated 102F water temperature drop at 55F
ambient air temperature is about half a degree Fahrenheit in a well
insulated spa. Heater will not start at this point until next cycle. Tem-
perature must drop by 1F before heater is activated.

IN A HURRY - READ THIS
SmarTouch Digital comes to you with a universal set o de ault
settings. I 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
The UP(T MP) & DOWN(TIM ) arrows.
Press and hold for 2 sec. the UP (T MP) arrow key.
Controller will display current spa temperature.
Use the UP or DOWN arrow keys to select
desired temperature.
*To enter new temperature press → S T key.
The controller will:
- Lock-in the new temperature.
- Display current spa temperature.
IMPORTANT: Always turn down the heat before you drain the spa.
*Note:
Once you select the T MP or TIM and the S T key is not pressed within
30 seconds the controller reverts to the previous setting and the change
will not take effect.
The SET Key
After using the spa, press the S T key to tell the micro controller 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.
Both buttons are used to select, increase
or decrease temperature or time setting.
Note: Both keys are active when pressed
individually and held down 2 seconds, to
eliminate accidental changes.
Page 23 Page 4

SETTING TIME-OF-DAY
Setting Time-O -Day
Press and hold for 2 sec. the DOWN (Time) arrow key.
Controller will display 12:00 noon. Use OR to set the
correct time-of-day.
*After every selection “Hours , Minutes” press → S T key.
Cool-Down Timer
A 30-second timer keeps the low speed jets, ON, after the heater turns
OFF, to remove all residual heat from the heater element.
User Timer
A built-in, 20 minutes elapsed-time clock switches off any active function.
Economy mode. Water & Energy Management.
The Economy mode manages water temperature, filtration and energy
consumption knowing “when” to heat to maintain water temperature.
The conomy mode starts when the heater is turned off and the spa is
not in use.
Upon entering the CONOMY mode the message “ECON” is displayed.
During the conomy mode the spa controller is in stand-by, three hours
at a time, monitoring and sampling the water temperature.
At the end of every conomy period which is 3 hours the controller ac-
tivates the low jets only for 5 minutes to perform the following:
1-Filter and sanitize the water. Check your spa manual for the type of
sanitizer in your spa.
2- Stabilize the water temperature and heat if necessary, in that case the
low jets run more than 5 minutes for the duration of the heating cycle.
Important: Tie down your spa cover to minimize heat loss and to con-
serve energy.
Note: The message “ECON” is not an error code.
