Congratulations on purchasing the most advanced microprocessor-controlled, hot water recirculation pump controller made. This system is designed to run the recirculation pump only when you need it thus saving both water and energy. It is designed and built with pride in the USA to provide years of service and savings.
1 Smart Thermostatic Control 32 with RJ-45 connector
1 ¾” or 1” NPT Flow Sensor with JST connector
1 Wiring Harness with R-J45 & JST connectors
Items NOT included: The following items are needed for the installation but are not included.
→ PTFE (Teflon) Tape
→ Wire fasteners for securing wiring to the wall
Perform the following system test.
If this test fails, inspect the wires connecting to the flow meter to ensure they are not broken or loose. Reconnect the connection ensuring it snaps tightly and re-test.
NOTE: PTFE tape is necessary when connecting to a female NPT connector. PTFE tape is NOT necessary when connecting to a flexible hook-up line as they have a washer that creates the seal. If installing in hard copper piping it is recommend to install the flow meter using a union fitting.
If the pump fails to turn on or fails to stay on past the initial 5 seconds or continues to run after you have hot water at the faucet(s) where the crossover valve(s) is (are) installed, see Troubleshooting.
GREEN LED: will blink 3 times when first plugged in to indicate the unit is functioning correctly.
GREEN LED: solid on when a timer is active and the pump is not running.
GREEN LED: will blink every 10 seconds when no other LED is lit (e.g. no timer active, pump not running)
RED LED: solid on when the pump is running whether due to a timer or due to demand.
BLUE LED: solid on when connected via the smartphone app.
Please read over the following detailed instructions. If you are not comfortable with any part of them please contact a licensed plumber to perform the installation.
Prior to installation, you must perform the system test at the beginning of the Quickstart Guide.
Be prepared with some towels as some water will flow out of the hookup line. As long as all the faucets remain closed you should not get any backflow from the hot water line.

(1) Smart Recirculation Control 32 with RJ-45 connector
(2) Temperature Sensors with RJ-14 connectors and RJ-14 Splitter
(1) 3/4” or 1” NPT Flow Sensor with JST connector
(1) Wiring Harness with RJ-45, RJ-14, and JST connectors
Items Note Included: You will need the following items for installation that are not included.
→ Electrical Tape
→ PTFE (Teflon) Tape
→ Wire fasteners for securing wiring to the wall
Perform the following system test.
If this test fails, disconnect all connections and inspect the wires to ensure they are not broken or loose and that the pins in the Y connector are not pushed to one side or the other.
NOTE: If the controller light blinks fast red, the issue is with a temperature sensor connection at the Y connector. See Troubleshooting Symptom 1.
NOTE: PTFE tape IS necessary when joining the flow meter to a female NPT connector. PTFE tape is NOT necessary when connecting to a flexible hook-up line, as they use a washer to create a seal. If installing with hard copper piping, it is recommended to install the flow meter using a union fitting.
Do not attach it to a coupler, corrugated flex pipe or a hookup hose. Cover the temperature sensor with insulation. The temperature sensor lines can be extended with RJ-14 telephone line extensions if needed. Tested extensions can be purchased from the online store.
Do not attach it to a coupler, corrugated flex pipe or a hookup hose. Cover the temperature sensor with insulation.
If the pump fails to turn on or fails to stay on past the initial 10 seconds or continues to run for longer than 5 minutes and the piping feels hot, see Troubleshooting.
GREEN LED: will blink 3 times when first plugged in to indicate the unit is functioning correctly.
GREEN LED: solid on when a timer is active and the pump is not running.
GREEN LED: will blink every 10 seconds when no other LED is lit (e.g., no timer active, pump not running).
RED LED: fast blinking indicates that one or both of the temperature sensors are not connected properly.
RED LED: will blink every 5 seconds when Max Pump Run Time is exceeded.
RED LED: solid on when the pump is running, whether due to a timer or due to demand.
BLUE LED: solid on when connected via the smartphone app.
Please read over the following detailed instructions. If you are not comfortable with any part of them, please contact a licensed plumber to perform the installation.
Before installation, you must perform the system test at the beginning of the QuickStart Guide.
Do not attach it to corrugated copper pipe, the hook-up hose, or a coupler. Cover the temperature sensor with insulation.
PEX is a good insulator and will cause a lag in the controller sensing the temperature change. You will need to plumb in a short section of copper pipe and attach the temperature sensors to the copper pipe instead of attaching the sensors directly onto the PEX.
Do not attach it to corrugated copper pipe or a coupler.
Cover the temperature sensor with insulation. You may install the sensor downstream from the pump; however, the pump absorbs heat requiring it to run longer before the temperature sensor detects the increase in temperature.
Temperature sensor must be placed before the return line T’s back into the cold water supply line.
NOTE:This is the primary source of issues when installing the controller. If, when the controller is plugged in, the indicator light blinks fast red, the problem is with a temperature sensor connection at the Y connector.
