Installing the Hot-LinkPlus-e Hot-Link Valve:
1.
Select the hot water faucet furthest from the water heater. If
your plumbing system branches in two
different directions,
another Hot-Link Valve may need to be installed at the end of
each run (see Figure 1 on page 1).
3. Open the hot and cold faucets to purge water from the lines.
4. Disconnect the hot and cold flex hoses from the 1/2" faucet
connections beneath the sink and reconnect them to the
respective hot and cold inlet ports on the Hot-Link Valve.
Locate the flow arrows on the side of the valve to verify flow
direction.
5. Install the 1/2" x 1/2" flex hoses provided. Connect one hose to
the hot outlet of the valve and the hot water connection on the
faucet (left side). Connect the second flex hose to the cold
outlet of the valve and the cold water connection on the faucet
(right side). See Figure 5 below.
6. When all connections are made, open angle stop valves and
check for leaks.
7. Attach the Hot-Link Valve to the wall using anchor
screws provided.
NOTE: The Hot-Link Valve can be disassembled for service and
cleaning. Repeat steps number 2 and 3. Unthread the valve stem
from the body and clean internal screen of debris (see Figures 3 &
4 above). Reattach valve stem securely to prevent leaks. Open
angle stop valves and check for leaks.

Application:
Taco's Hot-LinkPlus-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.

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.
