APPLICATION:
The Taco SmartPlus-e™ consists of a 006e3™ ECM high-efficiency circu­lator combined with our SmartPlug Instant Hot Water Control®. The SmartPlus-e is designed to increase hot water comfort while conserving water and energy. By recirculating “cooled” hot water back to the water heater, the wait for hot water is reduced to seconds. A dedicated hot water recirculation line within the piping system is required.
The SmartPlus-e System includes a high-efficiency Taco multi-speed 006e3 ECM permanent magnet circulator. The circulator is suitable for
most residential homes with hot water supply lines up to 300 feet.
SmartPlug Instant Hot Water Control learns weekly hot water usage patterns in the home. It uses that information to run the 006e3 providing hot water when its needed.
2. Install all other system components as shown in the piping diagram in Figure 1.
3. When all components are installed, fill system with water.
4. Close the isolation valve on the return line between the water heater and the flow check valve.
5.
Open the drain valve between the isolation valve and flow check valve and drain water until all air is purged from the line.
6. Close drain valve and open isolation valve.
WARNING: All local plumbing and electrical codes should be followed when installing this product.
CAUTION: To ensure all plumbing system components are protected from the damaging effects of water hammer, be sure an approved water hammer arrestor is installed in the system per locally recognized National plumbing codes.
CAUTION: Do not plug in the 006e3 circulator power cord until the system is filled with water and purged of air.
WARNING: The 006e3 circulator must be installed and supported by the circulation piping.
Installing the SmartPlus-e 006e3 Circulator: Hot Water Return Line (Option No. 1)

Application:
Taco's SmartPlus-e SmartPlug Instant Hot Water Control® is designed to upgrade any hot water recirculation system. SmartPlug replaces inefficient timers and aquastats typically used in recirculation systems. It adds intelligence to your system by learning when hot water is used in the home. The pipe-mounted sensor records daily hot water usage patterns during the course of the week. Recorded data is used to automatically run the 006e3 at the same times the following week. So hot water is awlays available when it is needed. If usage pattern changes, the SmartPlug adjusts automatically.
Benefits:
• Easy to Install: Upgrades the SmartPlus-e 006e3 circulator to
“Smart” operation.
• Comfort and Convenience: Hot water is available in seconds. No
rs or progratime mming required.
• Efficiency: “Smart” mode maximizes hot water
comfort and energy
savings.
• Reliability: The SmartPlug, when combined with the 006e3
circulator, provides whisper quiet operation and industry leading electronics for proven performance and dependability.
SmartPlug Control Options/Features:
“Smart” Mode: When set to Smart mode, the SmartPlug will run
in Pulse mode as described below for the first 7 days of operation. During the first 7 days, the SmartPlug monitors and records the home's hot water usage pattern. For the following 7 days, the SmartPlug will use the preceding week's usage pattern to cycle the 006e3 during the recorded hot water usage times. This process of recording and repeating is continuous, and automatically adjusts the 006e3 ON times to match the household's usage pattern.
• “Pulse” Mode: When set to Pulse mode, the SmartPlug will cycle
the 006e3 ON for 5 minutes, then OFF for 10 minutes to maintain hot water at all faucets and taps. It will repeat the cycle con­tinuously.
Vacation Mode: After 36 hours of no hot water usage, the
SmartPlug will automatically turn the 006e3 OFF, and will auto­matically restart when hot water usage is detected.
Exercise Function: While in vacation mode, the SmartPlug will
cycle the 006e3 ON for 10 seconds every 7 days to prevent corrosion or scale buildup
SmartPlus-e SmartPlug Installation:
1. The SmartPlus-e SmartPlug is designed for use with Taco’s SmartPlus-e 006e3 ECM High Efficiency Circulator.
2. Using the black sensor strap provided, attach the SmartPlug sensor to the HOT water supply pipe from the water heater. USE
EXTREME CAUTION WHEN INSTALLING THE TEMPERA­TURE SENSOR ON THE HOT WATER SUPPLY PIPE AS PIPE TEMPERATURE MAY BE EXTREMELY HOT. The sensor must
be strapped at least 18" away from the hot water source to ensure proper sensor temperature readings. The "flat" side of the sensor should be strapped directly to the hot water supply pipe using the black sensor strap provided. If the supply pipe is insu­lated it will be necessary to remove the insulation at the point where the sensor is installed to ensure accurate sensor readings.
3. Install the SmartPlug temperature sensor. Connect the 2 wire leads on the temperature sensor to the green sensor connector terminal block by loosening the 2 set screws. Insert the 2 wire
leads from the temperature sensor into the terminal slots on the terminal con­nector and tighten the 2 set screws. Be careful not to over tighten screws as you may damage the terminal con­nector. Once the temperature sensor wires are securely fastened, insert the terminal block into the SmartPlug receptacle labeled "SENSOR". NOTE: The SmartPlug sensor is provided with a 10' lead wire. Some installations may require a sensor lead wire in excess of 10'. If the sensor lead length needs to be increased, standard "18 AWG" gage wire and 2 wire nuts can be spliced into the temperature sensor lead wires to extend the overall length.
4. Plug the SmartPlug into a properly grounded 120V wall outlet. LED’s will illuminate and a 10 second diagnostic check will begin.
5. Plug the 006e3 circulator 120V line cord into the SmartPlug. The
blue LED will illuminate on the face of the 006e3. NOTE: The 006e3 circulator is double insulated so does not need to be grounded.
.
Setting the SmartPlus-e SmartPlug Operating Mode:
1. The SmartPlus-e SmartPlug has a MODE SELECT push button
on the bottom of the control that allows for 2 operating modes. "Smart" or "Pulse" mode can be selected by pressing the MODE SELECT button located on the lower right side of the control box. To set the mode, make sure the SmartPlug is plugged into a properly grounded 120V outlet. A yellow LED labeled "MODE" on the face of the SmartPlug identifies the mode selected.
