AQUA SMART APPLICATIONS:

Q. What water heaters can the Aqua Smart® be installed on?

A. The Aqua Smart® is designed to be installed on 208/240 volt electric hot water heaters not to exceed wattage ratings greater than 6000 watts. Most residential water heaters are rated between 3000 and 6000 watts. The Aqua Smart® should not be installed on any water heater with a ampere rating greater than 30 AMPS/6000 watts.

Q. Can the Aqua Smart® be installed on gas powered water heaters?

A. No. The Aqua Smart® operates on the incoming electric power which operates the electric water heater. Most gas water heaters do not operate on external electrical power and what small electrical voltage the gas water heater operates on is generated by the gas valve’s millivolt system.

Our company has investigated the possibility of developing a model for gas water heaters but the gas valve manufactures state that a typical gas valve, operating a gas water heater, has a limited capacity for multiple rotations of the thermostat dial/shaft. The seals on the thermostat shaft are designed for typical homeowner OFF-TEMP SELECTION and VACATION intermittent rotations.

The difference between the Aqua Smart® system for electric hot water heaters and one for gas water heaters is that the operating mechanism for a gas water heater will require a battery-operated, servo mechanism to rotate the gas valve control dial, in a bi-directional motion. The excessive rotation of the dial on a gas valve could result in the premature failure of these seals causing a safety hazard. Our company has therefore decided not to pursue such a retrofit device.

Q. Is there a limitation to the size of the water heater, relative to the number of gallons that the Aqua Smart® can be installed on?

A. No. A water heater is rated by the electrical current it draws to heat the water not by the capacity of the water tank. The water heater capacity and electrical rating is determined, at the factory, by the manufacturer. Again, the Aqua Smart® is designed to operate on water heaters that are rated 30 amps or less.

Q. Can the Aqua Smart® be installed on 110 volt water heaters?

A. Yes but only by an electrical technician who is knowledgeable of the receiver’s circuit wiring. The Aqua Smart® was specifically designed to operate on 208-240 Volt water heaters.

Q. Has the Aqua Smart® been safety tested by a recognized, independent, testing agency for installation in the US?

A. Yes. The Aqua Smart® has been tested by INTERTEK, a worldwide, recognized, testing agency and CONFORMS to UL STD 873.

Q. Can the Aqua Smart® be installed on water heaters in Canada?

A. Yes. The Aqua Smart® has been tested by INTERTEK, a worldwide, recognized, testing agency and is CERTIFIED to CSA STD C22.2 NO.24

AQUA SMART® SYSTEM COMPONENTS:

Q. What components come with the Aqua Smart® system?

A. The Aqua Smart® system consists of a TRANSMITTER and a RECEIVER. These 2 components operate “wirelessly”, using a 2-way communication protocol. The RECEIVER mounts on top of an electric hot water heater and the TRANSMITTER can be wall-mounted up to 100 feet from the receiver.

INSTALLATION QUESTIONS:

Q. Is it safe for a homeowner to make such an installation?

A. The easiest way for a homeowner to determine the skills necessary to install the Aqua Smart® system is review the INSTALLATION VIDEO, which can be viewed by clicking HERE or on the VIDEO tab above. Also, copies of the OWNERS MANUALS, in both English and French, can be viewed by clicking HERE or on the OWNER’S MANUAL tab below.

Q. How easy is the RECEIVER to install on the water heater?

A. Once the power is turned off, at the breaker panel, the installation of the RECEIVER is a relatively easy task. There are 3 incoming wires that power the electric hot water heater. These wires are detached from the water heater’s junction box and re-installed to clearly marked wires inside the RECEIVER.

Q. I am not comfortable installing electrical products so where do I find a qualified installer to install the Aqua Smart®?

A. For those individuals not comfortable or familiar with installing electrical products, contact any qualified electrician or plumber to install the Aqua Smart® system. As there are no plumbing fittings to be changed, either qualified professional can easily install the system.

Q. How long will it take to install the Aqua Smart?

A. Based on the skills of the installer, and availability of simple tools necessary to perform the installation, it should take between 45 minutes to 1 hour.

Q. What tools are required to install the Aqua Smart® ?

A. Basic tools include an electric drill with a 1/8″ bit, Phillips head and straight blade screwdrivers, small adjustable wrench, a punch, hammer and some type of circuit tester to be sure the power to the water heater has been disconnected prior to installing the RECEIVER.

Q. Does it matter where the hot water heater is installed?

A. The answer to this is a qualified, no. As the TRANSMITTER communicates with the RECEIVER, and the

RECEIVER communicates with the TRANSMITTER using a 2 way protocol, the distance and location of the

TRANSMITTER that is of utmost importance. The maximum operating distance is 100′ depending on any structural or RF interference between the TRANSMITTER and the RECEIVER.

 

TRANSMITTER SET UP/OPERATION & BATTERY DATA:

Q. What determines the location of the TRANSMITTER?

A. Normally the “wireless” TRANSMITTER can be installed from 75′-100′ from the RECEIVER. The determination of this is made following the “learning” procedure when the RECEIVER learns one of the 1,048,576 security codes embedded in the TRANSMITTER’S software. During the initial set up of the system, the homeowner moves the TRANSMITTER to a location in the home, preferably near the home’s heating/cooling (HVAC) thermostat, and wall mounts the TRANSMITTER there.

Every rule has its exception and this distance can be restricted due to interference caused by steel partitions/beams, interference from other wireless devices in the home or hi-power electrical interference between the RECEIVER and TRANSMITTER. The homeowner must be cognizant of this limitation.

Q. Does the TRANSMITTER have to be wired to the hot water heater or RECEIVER?

A. The unique advantage of the Aqua Smart® system is that the TRANSMITTER operates on 2 – AAA Alkaline batteries and “wirelessly” communicates with the RECEIVER sending and receiving signals without the need of “hard – wiring” that is required by most heating, ventilation, and air conditioning (HVAC) thermostats.

Q. How long will the TRANSMITTER batteries last before needing replacement?

A. The batteries should last from between 12-15 months. There is a low battery icon on the TRANSMITTER LCD screen indicating a low battery condition. In addition to the low battery icon, the TRANSMITTER will emit  3 – second long “beeps”, every hour, alerting the homeowner that the batteries should be replaced within 2 weeks. Replace batteries with 2 new, AAA, ALKALINE batteries for dependable operation of the system. When the batteries are replaced, the TIME, F/C and DAY must be re-entered into the TRANSMITTER. The BALANCING and WATTAGE settings are stored in the microprocessor and do not need to be re-entered.

Q. What happens when the batteries fail and the homeowner is not around to change them for a few weeks.

A. If the batteries lose all power, the RECEIVER defaults to the last MODE setting and operates the water heater to the temperature ranges of that mode. When the batteries are replaced, then the modes can be changed.

Q. What is the thermometer strip that came in the TRANSMITTER package?

A. A small thermometer has been supplied instructing the user to measure the ACTUAL temperature of the hot water coming out of a water faucet supplied by the water heater. During the initial set-up procedure, user MUST adjust the SENSOR TEMP temperature, on the TRANSMITTER’S LCD screen, to the actual water temperature coming from a HOT water faucet in the home. We refer to this process as “BALANCING” the water temperatures.

A popular option to using the Thermometer Strip is to use a Digital Meat Thermometer to record the water temperature from the faucet. The digital thermometer will give a more specific temperature than the thermometer strip. Using an INDOOR/OUTDOOR thermometer probe will provide the most accurate temperature reading.

From a faucet nearest the hot water heater, fill a glass with hot water and drop the temperature strip into the water. If using a digital thermometer, insert the thermometer’s probe into the hot water glass. Observe the reading on the temperature strip/thermometer comparing this reading to the SENSOR TEMP reading on the TRANSMITTER’S LCD screen and then enter a corresponding “balancing” number on the TRANSMITTER LCD screen by adjusting the UP or DOWN buttons. See OWNER’S MANUAL for instructions.

Q. Describe the “BALANCING” process.

A. After the RECEIVER has been installed on the water heater and the MTA (Magnetic Thermal -Sensor Assembly) has been attached to the hot water tank, follow the procedure below:

  1. From a faucet nearest the hot water heater, fill a glass with hot water and drop the temperature strip into the water. If using a digital thermometer, insert the thermometer probe into the hot water glass.
  2. Observe the reading on the temperature strip/thermometer comparing this reading to the SENSOR TEMP reading on the TRANSMITTER’S LCD screen and then enter a corresponding “balancing” number on the TRANSMITTER LCD screen by adjusting the UP or DOWN buttons.
  3. See OWNER’S MANUAL for detailed instructions.

Q. What do the 2 arrows at the top of the TRANSMITTER screen indicate?

A. These arrows, referred to as SYNC arrows, indicate that the 2-way communication between the TRANSMITTER and the RECEIVER is occurring and the system is working properly.

Q. What does the warning triangle at the top of the TRANSMITTER screen indicate?

A. When the warning triangle icon displays it indicates that the communication protocol between the TRANSMITTER and RECEIVER has been interrupted. This can occur when the TRANSMITTER is out of the radio-frequency (RF) operating range with the RECEIVER. When this happens, a series of 4 rapid “beeps” will be emitted, every 30 minutes, by the TRANSMITTER alerting the homeowner to resolve the problem.

Q. What is the importance of entering the water heater wattage rating in the initial set-up?

A. The importance in entering the correct wattage rating of the water heater is what determines the kilowatt (kWh) energy usage of the water heater which is displayed on the TRANSMITTER’S LCD screen. The kWh number displayed is a calculation of the electrical usage of the water heater when the water heater is operating. This data is stored in the TRANSMITTER for 30 days and then the number is reset to “O”. Resetting this number allows the homeowner to review the electrical usage of the water heater for a 30 day period.

The homeowner can calculate the cost of the energy consumed, to operate the water heater, by multiplying the kWh usage by the utility company’s rate charge found on the homeowner’s monthly electricity bill.

The TRANSMITTER also stores 12 months of data so the homeowner can review the electrical usage of their water heater comparing monthly usage. See OWNER’S MANUAL for complete instructions on data storage and resetting.

Q. What is the difference between the AWAY and VACATION modes.

A. When the AWAY mode is engaged, the TRANSMITTER maintains the water temperature between 75 F and 85 F degrees. This setting is recommended when the homeowner is to be away from the home from between 3-5 days, reducing energy consumption. This allows for the rapid recovery of the hot water when the homeowner returns home, and enters the ON mode, returning the water heater to its normal operating status. (Corresponding readings display if the TRANSMITTER has been programmed in Celsius -C degrees).

When the VACATION mode is engaged, the TRANSMITTER maintains the water temperature between 40 F and 50 F degrees. This setting is recommended when the homeowner will be away from the home for longer periods of time, up to several weeks or months. The water temperature is maintained above the freezing point making the Aqua Smart® an ideal device to install in vacation homes, as long as there are no extended power outages affecting the home, as freezing temperatures can damage the water heater. (Corresponding readings display if the transmitter has been programmed in Celsius – C degrees).

Q. I noticed that, at times, the temperature, on the TRANSMITTER screen, is above the upper limits of various modes. Why does this occur?

A. To preserve battery power, the TRANSMITTER and RECEIVER only communicate with each other every 30 minutes. This may cause the SENSOR TEMP window, on the TRANSMITTER screen, to show a higher or lower temperature, following the initial “powering” of the water heater.   It may appear that the high end of the selected mode temperature range has not shut off the power to the RECEIVER but that can be verified by viewing the LED lights on the RECEIVER. The ON LED will not be illuminated but the selected MODE LED will remain illuminated awaiting the next On/OFF command.

 ***There is an “override” to the 30 minute delay,  referred to as “INSTA-TEMP”, (see owner’s manual), which can be engaged with a single push of the SET button on the TRANSMITTER.***

 Q. How can I determine if the water heater is being powered without looking at the LED lights on the RECEIVER?

A. On the TRANSMITTER, you will see the word HEATING and STEAM TRAIL icons at the bottom of the LCD screen.

 EXCEPTION: ONLY in the ON made will this icon be blinking ALL THE TIME.

 In the AWAY,VACATION and PROGRAM modes, this icon will be blinking ONLY when the water heater is being “powered” in these modes. When these icons are not visible, in these modes, the water heater is not being “powered”.

Q. I noticed the letters EE are showing in the SENSOR TEMP window on the TRANSMITTER screen. What does this mean?

A. It is important that you determine that the power to the water heater has not been disconnected. Also, inspect the MTA/THERMISTOR WIRE that comes from the RECEIVER, (attached to the water tank by a magnet), is firmly in place. If this wire is disconnected, cut or the thermistor head is damaged the thermal data collected from the hot water tank will not be processed by the RECEIVER and the TRANSMITTER will not be able to operate the Aqua Smart® system. The EE letters alert you to this communication problem.

 

RECEIVER SET UP/OPERATION:

Q. What is the LEARN button, on the RECEIVER, for?

A. The learn button is used during the initial set-up of the Aqua Smart® system. Before the Aqua Smart® system’s components can communicate with each other, the TRANSMITTER teaches one of 1,048,576 security codes embedded in the TRANSMITTER’S software to the RECEIVER.

After the RECEIVER has been installed on the water heater, and the power has been activated, depress and release the LEARN button on the RECEIVER and you will hear a LONG BEEP. Now, press the MODE button on the TRANSMITTER and you will hear 5 RAPID BEEPS confirming the RECEIVER has “learned”  the TRANSMITTER’S security code completing the “learning” process.

Q. What is the purpose of the MTA/Thermal Sensor wire attached from the RECEIVER?

A. The MTA (MAGNETIC THERMAL-SENSOR ASSEMBLY wire is of critical importance to the proper operation of the Aqua Smart® system. It is from this MTA that the RECEIVER receives temperature data, from the hot water tank, which is then relayed to the TRANSMITTER. The TRANSMITTER’S microprocessor uses this temperature data to determine when to signal the RECEIVER to “power” the water heater, ON or OFF, based on the program inputted into the TRANSMITTER by the homeowner.

What is of utmost importance is that, during the set-up procedure of the TRANSMITTER, the “Balancing” procedure is followed and that the MTA THERMAL SENSOR reading and the temperature of the hot water heater are “balanced”. Without programming this important information into the TRANSMITTER the system will not operate to its maximum capability.

 

WATER HEATER WATTAGE RATINGS:

Q. My water heater label has two different wattage ratings on the side of the water heater. Which one do I enter in the transmitter?

A. Your water heater may have VOLTAGE RATINGS listed in separate columns designated 208 V and 240 V.

  •  For installations in the United States, you should record the ratings under the 240 V column.
  • For Canadian installations, use the rating numbers under the 208 column. The US and Canada operate on 2 different voltage systems.

Q. The label on my water heater indicates that there is an upper heating element and a lower heating element. What does this mean? Both elements have the same rating. Do I add these numbers together and enter the resulting number into the transmitter?

A. No. On most 208-240 V water heaters there are two heating elements which are rated the same. You only enter one number. For example, if the rating on each of the elements is 4500 W, then enter only 4500 W into the transmitter at the initial setup.

In some newer water heaters, the bottom element MAY have a lower wattage rating. This has been done, by some water heater manufacturers, to reduce the power consumption in the “standby” mode. Should the lower element rating be lower than the top element rating, we recommend that you input the TOP element rating into the TRANSMITTER during the initial setup procedure. For example, if the TOP element is rated at 4500 watts and the bottom element is rated at 3800 watts, enter 4500 into the TRANSMITTER during the initial setup.

 

ELECTRICAL POWER FAILURES:

Q. What happens if there is a power failure? Will the Aqua Smart® restart or is there a reset switch that has to be activated on the RECEIVER?

A. When there is a power failure and the RECEIVER loses power, when the power resumes, the RECEIVER will return to the last mode setting the Aqua Smart® system was operating in.

Q. What happens if the RECEIVER fails? Will I still have hot water?

A. YES. The RECEIVER has a BY-PASS breaker switch located at the front of the RECEIVER. The normal operating position for this switch is in the AUTO position. Should an unlikely failure of the RECEIVER occur, switching the breaker handle to the BY-PASS position allows the electric power to flow directly to the hot water heater, by-passing the Aqua Smart® RECEIVER.

Please review the TROUBLE SHOOTING section in the Owner’s manual to diagnose any problems you may be having with your water heater.

 

SAFETY TESTING AND CERTIFICATIONS:

Q. Has the Aqua Smart® been safety tested by a listing agency for use in the United States?
