Installing the SmartPlus-e 006e3 Circulator

Hot Water Return Line (Option No. 1)

1. Install the SmartPlus-e 006e3 circulator in-line on the DHW return line pumping toward the hot water source as shown in Figure 1. Be sure the directional arrow on the casing is installed with the arrow pointing toward the hot water source.
2. Install all other system components as shown in the piping diagram in Figure 1.
3. When all components are installed, fill the 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 the drain valve and open the isolation valve.

To change operating speed settings

Modify the performance of the 006e3 as needed by rotating the programming dial using a flat screwdriver. A blue LED will illuminate when the circulator is powered on. The LED will flash each time mode is changed. The selection of the right performance curve depends on the characteristics of the system and the actual flow and head requirements. See 006e3 Performance Curves and Setting Selection Guide on page 3 to determine best speed setting for the system. NOTE: If flow velocity noise develops, turn dial counter-clockwise to reduce pump speed until the noise disappears.

Hot Water Supply Line (Option No. 2)

1. Install the SmartPlus-e 006e3 circulator in-line on the DHW supply line as shown in Figure 3. Be sure the directional arrow on the casing is installed with the arrow pointing away from the hot water source.
2. Install all other system components as shown in the piping diagram in Figure 3.
3. Follow steps 3 through 6 listed under the Hot Water Return Line (Option No. 1) section.

Installing the SmartPlus-e SmartPlug Instant Hot Water Control®

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 the 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. Nors or programming 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 auto-matically 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 TEMPERA-TURE 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 connection. Once the temperature sensor wires are securely fastened, insert the terminal block into the SmartPlugreceptacle 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.LEDs 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
