Installation Guide

8. Plug the external temperature sensor provided into the “TEMP SEN-
SOR” receptacle on the side of the capacitor base. Attach the sensor
to the hot water supply pipe downstream of the pump using the black
zip-tie connector provided.
Once the system is filled and air is purged, plug in the SmartPlus
power cord.
NOTE: The temperature sensor must be installed and connected
in either “Pulse” or “Smart” mode.
NOTE: The SmartPlus must be installed and supported by the
circulation piping.
Hot Water Return Line (Option No. 2) - Install the SmartPlus on the
domestic hot water (DHW) return line pumping toward the DHW source.
The external sensor provided with the SmartPlus should be installed on
the DHW supply line. Refer to Figure 2.
1. Install the SmartPlus in-line on the DHW return line as shown in
Figure 2. Be sure the directional arrow on the casing is installed with
the arrow pointing toward the hot water source.
2. Follow steps 2 thruough 7 listed under the Hot Water Supply Line
(Option No. 1) section.
3. Plug the external temperature sensor provided into the “TEMP SEN-
SOR” receptacle on the side of the capacitor base. Attach the sensor
to the hot water supply pipe using the black zip-tie connector provided.
NOTE: The temperature sensor provided may not have enough
wire length to reach the DHW supply pipe with the SmartPlus
installed on the return line. In this case, standard low voltage
doorbell wire (not included) can be spliced into the sensor line
increasing the overall sensor wire length.
Once the system is filled and air is purged, plug in the SmartPlus
power cord.
NOTE: The temperature sensor must be installed and connected
in either “Pulse” or “Smart” mode.
NOTE: The SmartPlus must be installed and supported by the
circulation piping.
OTHER SPECIAL FEATURES OF THE SMARTPLUS:
1. Vacation Function - If no water usage is detected for 36 hours, the
pump will remain off until hot water usage is detected. Once detect-
ed, the pump will resume operation.
NOTE: If pump is set to “Smart” mode, the pump will operate in
“Pulse” mode for the first 7 days while recording usage patterns.
2. Exercise Function - While in vacation mode, the pump will come on
every 7 days and run for 10 seconds to prevent any corrosion or scale
buildup.
3. Power Outage - When power is restored, pump will revert to its mode
setting, either “Pulse” or “Smart”. If in “Smart” mode, previously
recorded data will not be saved and the pump will begin a new 7 day
usage learning cycle.
4. LED - The SmartPlus is provided with 3 LED’s located on the side of
the capacitor base.
Green LED – Illuminated - Power On
Yellow LED – Flashing - Pump in “Pulse” mode
Illuminated (not flashing) - Pump in “Smart” mode
Red LED – LED off - Sensor is connected properly
LED flashes once every 5 seconds - Shorted sensor
LED flashes twice every 5 seconds - Open sensor
