Taco SmartPlus-e User manual

APPLICATION:
The Taco SmartPlus-e™ consists of a 006e3™ ECM high-efficiency circu-
lator 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.
HIGH QUALITY FEATURES:
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.
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 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.
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 4. 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 4.
3. Follow steps 3 through 6 listed under the Hot Water Return Line
(Option No. 1) section.

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.
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 noise disappears.

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 con-
tinuously.
•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 insu-
lated 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 con-
nector and tighten the 2 set screws. Be
careful not to over tighten screws as
you may damage the terminal con-
nector. 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.
“Smart” Mode: Solid Yellow LED
“Pulse” Mode: Blinking Yellow LED
Press and release the MODE SELECT button once to change
the mode.
2. The SmartPlug is also provided with a red "SENSOR" LED. If the
sensor is properly installed the “SENSOR” LED will not illumi-
nate. If the red LED is flashing, refer to the troubleshooting sec-
tion below.
3. Installation and mode selection are complete.
4. To ensure the SmartPlug is providing hot water properly, open a
hot water tap at the fixture furthest away from the hot water tank.
Use CAUTION as the water may be extremely hot.
