Demand-Sensing Hot Water Recirculation Control
Don't be fooled by cheap, imported imitations. Only the the Smart Recirculation Control and the AquaMotion valve and pump are made in the USA. And only the Smart Recirculation Control comes with the AquaMotion high flow thermostatic crossover valve that provides fast, on demand, hot water to all locations in your house. The inexpensive, plastic valves from Grundfos/Watts just don't have the water flow necessary to quickly heat up the water when you demand it.
The Smart Thermostatic Control is a demand-sensing hot water recirculation control system designed for homes without a dedicated hot water recirculation loop. It works with the AquaMotion high flow thermostatic crossover valve AMK-ODR. Rather than running the pump all the time or on a timer, the Smart Recirculation Control waits until it senses hot water being used anywhere in the house and then turns the pump on. When the pump runs it pushes water through the AquaMotion AMK-ORD thermostatic crossover valve from the hot water line to the cold water line. Once the hot water reaches the thermostatic crossover valve it closes and stops the flow of water. The Smart Recirculation Control senses that water has stopped flowing and turns the pump off. The controller then goes dormant for a user configurable period of time so it isn't switching the pump on immediately after heating the system up (default 10 minutes).
The Smart Thermostatic Control demand-sensing hot water recirculation control system is configured via a smart phone app with "Live Flow" TM, which shows the flow meter value in real time. This allows you to easily configure the "on" and "off" flow values independently but tests have shown that the default values work well in most installations.
The Smart Thermostatic Control is also configurable to run via timers in order to heat the system up on a schedule. The controller will turn the pump on, allow it to get up to speed and run it until the flow drops below the "off" value. It will then go to sleep for the dormant period before testing the system for flow again. Of course, outside of the timer periods the controller will still run the pump on demand.
It couldn't be simpler!
This is the smartest way to install an on demand hot water system in a house that doesn't have a dedicated hot water recirculation loop. The Smart Thermostatic Control works with both tank and tankless water heaters. The tank water heater version has a thermostat that gets attached to the hot water outlet pipe from the water heater to ensure that the temperature of the hot water is greater than 95F to prevent lukewarm water from being pumped throughout the house. Tankless water heaters don't need this extra check since they never run out of hot water.
Our demand-sensing hot water recirculation control system works well for homes that have multiple dead-end runs. You would install a thermostatic crossover valve at the end of each dead end run and a single pump at the water heater and all runs will heat up.
If all your hot water fixtures are on a single run or you only have one run you are interested in heating up, check out the Smart Recirculation Control retrofit package.
