SAVE THIS MANUAL
Make it available for 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 ELEMENT. 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 SET button.
1-Turn temperature down to lowest setting & press the SET key
2- Press SET 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 YES . 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.

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, LED 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.
