- 4. 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. 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. 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. Page 4
- 5. 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 ♦ Press and 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 of one hour is executed - that is when the spa needs filtration most. The rest of this manual will explain the function of each of the keys on the control panel. It will also explain all the error messages that you may encounter, their significance and a way to correct them. Page 5
- 6. SETTING FILTRATION TIME 1. Press and hold the TIME key for 2 seconds. 2. Release the TIME key 3. Using the UP and DOWN arrow keys, scroll up and down to the desired number of hours and minutes. 4. When the desired filtration time is displayed, press the SET key. The selected filtration time will repeat once every 12 hours. To change the start times, reset power to the spa. Page 6
- 7. 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, error codes and messages to the user. 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 3 device key, JETS, AIR OR AUX & LIGHT. Your spa will have at least one water pump. Optionally your spa may have an air blower, or a second pump and a spa light. 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 and while the spa is being heated. Page 7
- 8. 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 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. Spa Light In its simplest configuration, the LIGHT 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 LIGHT 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 page 9 summarizes all the possible device key combinations. Please not that your spa may not necessarily have all these devices attached. Page 8

SUMMARY OF FUNCTIONS FOR EACH DEVICE Key Device 1 2 3 4 Single speed pump ON OFF JETS Dual speed pump LOW HIGH OFF Dual speed with Circ pump LOW HIGH OFF Circ pump is independent AIR Single speed air blower ON OFF AUX One single speed pump ON OFF LITE Spa Light & Accessory ON ON Spa Light & Accessory ON OFF 3 Function OFF OFF OFF Table 1 - Device keys summary of functions The three device keys, JETS, AIR or 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.
- 10. 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 Filtration Time, - or Previous SET key. Select or Accept , Enter SET & TEMP (combination) Invert display 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 (UP) to increase selected temperature. 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
- 11. 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 filtration time ♦ Press UP or DOWN arrows to set the desired hours and minutes The SET key is equivalent to Select or Accept. It functions as an Enter key of a personal computer. Press the SET key to: ♦ After using the spa, press the SET key instructing 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 filtration time programming, press the SET key to lock in the hour and the minutes. ♦ When a “HLer ” 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
- 12. ERROR MESSAGES There are 9 error messages that a SmarTouch may generate. Here is a List of these messages and what they indicate: CoLd Temperature in the spa heater housing is below 40º Fahrenheit. Because spa temperature should never get this low, the status of the heater element is unknown. Therefore the low speed pump or circulation pump will run continuously until the temperature rises above 45º. A spa should not be filled with water below 40º. Please note that a running pump can heat the spa at approximately 1/2 degree F per hour. During this error condition, the spa is functional except for the heater. OH OverHeat. The spa is at a temperature that is above 108ºF. SmarTouch will not accept temperature settings above 104ºF. If for some reason spa temperature rises over the maximum level, SmarTouch will display a flashing 105ºF to 108ºF. If temperature goes past 108 then the OH message will be displayed instead of temperature. The spa is still operational but hotter than any person should be subjected to. Please do not use your spa when the temperature is flashing or the OH message is displayed. In the summer and especially in warm regions, ambient temperature may be high enough to overheat the spa naturally. Spas are usually well insulated and can store a lot of heat in the equipment compartment. HLer Hi Limit Over Heat. SmarTouch has a backup water temperature sensor called the HiLimit. If the sensor is disconnected or shorted or if the spa temperature should reach above 112ºF, the HiLimit protection circuitry will force all spa functions off and will flash the HLer message on the display. It is not possible to use the spa when this error is in effect, even after temperature goes down to an acceptable level or the sensor is repaired/replaced. When the error has been corrected, you must press the SET key to acknowledge that you, the spa user, are aware of the error condition and should have proper repairs done. Page 12
- 13. SEoP Sensor Open or disconnected and SmarTouch cannot determine the spa temperature. The heater is disabled but the spa is operational. The sensor must be replaced or reconnected for this message to go away. SESH Sensor Short. The sensor is shorted and is non functional. Temperature cannot be determined, the heater is disabled, but the spa is still operational. Sensor must be replaced to get rid of this message. PSoC, PSoL, PSoH Pressure Switch Open with Circulating, Low or High pump(s). The pressure switch is a device sensitive to pressure inside the heater manifold. Pressure in the heater manifold is generated by a pump pushing water through the manifold. If one pump is running and the pressure switch does not sense any pressure then there is an indication of no water flow. To prevent the heater from being turned on when there is no water running through, the heater is turned off and one of these messages will be displayed indicating which pump is supposed to be running. A pressure switch error may also be indicated if the switch is out of adjustment or there is an air lock in the pump. Adjusting the pressure switch is best left to a trained technician. An air lock may happen whenever the spa is so low as to permit air to be sucked in by the pump. To bleed an air lock; switch off power, loosen one of the pump fittings a quarter of a turn. You will hear the sound of escaping air, then water will start dripping. Re- tighten the fitting. ToE Time Out Error. It is not likely that you will ever see this error. It indicates that the system’s heartbeat is out of control, all devices will be shut down and the spa is unusable. This message will rarely ever occur, if it does, please contact Applied Computer Controls. PSSH Pressure switch closed (shorted). P/S closed while pump is turned OFF, indicating static water pressure is closing P/S. P/S needs adjustment. Page 13
- 14. ELECTRICAL CONNECTION INSTRUCTIONS NOTICE: All spa electrical wiring must be performed by a qualified licensed electrician and must meet all NEC (National Electrical Code) and state and local codes and requirements. DANGER - RISK OF ELECTRIC SHOCK 1. The lines carrying power to the spa must be dedicated to the spa and should not be shared with any other appliance(s). 2. All electrical wiring lines must originate from the electrical panel and terminate, hard wired, into the electrical wiring compartment. The useof extension cords or plug type termination is expressly prohibited and voids the warranty. 3. Do not use aluminum wiring. Use only copper wiring. 4. Wire gauge must be in accordance with NEC requirements for the distance from current source to spa and the current rating as stated on the ID label that is attached to the control enclosure. 5. All wiring must be shielded by a ground metal conduit. The conduit must terminate at the electrical access compartment either from the bottom of the spa or through a hole in the side paneling of the spa. 6. For a 120 volt system the line wire (black) is connected to the terminal block lug labeled LINE1. The neutral wire (white) is connected to the center lug labeled NEUT, and the ground wire (green) is connected to the ground lug labeled G or GROUND. 7. For a 240 volt 4 wire system, connected Line1, Neutral and Ground wires as in #6 above. The fourth wire is the Line2 wire (red) and it is connected to the lug labeled LINE2. 8. For a 240 volt 3 wire system, if applicable, connect black line wire to LINE1 terminal, connect red line wire to LINE2 terminal and the green wire to the ground lug. There is no neutral. Page 14
- 15. BRANCH CIRCUIT BREAKER REQUIREMENTS 240 Volts 4 Wire System 30/50 Amp 2 Pole Breaker 120 Volts 3 Wire System 20 Amp 1 Pole Breaker CAUTION : A new breaker must be used for a new spa installation. Do not use an existing or used breaker. GFCI. All spa installations must be protected by a GFCI. If your spa control box does not include an integrated GFCI then you must use a GFCI breaker per National Electrical Code requirements. 120/240 Volt Conversion. Please check the nameplate on the control enclosure to identify the type of system in your spa. If the nameplate indicates a 120/240 Volt type system, then it is possible to convert the spa to 120 volt operation. 30/50 Amp Conversion. Some homes may have limited power service. It is possible to operate a 240 volt spa system using a 30 amp breaker. Connect 240 volt power to the system as previously described, then set it to operate in the low power mode. Page 15
