We have had people ask if it is possible to relocate the temperature sensors by extending the line connecting the temperature sensor to the wiring harness. We had always responded with “no” because of support issues. But after receiving multiple inquiries asking if it could be extended by 75 ft. we decided to give it a try and are happy to report that the test was successful. We decided to go one further and test it out to 100 ft. and that test was successful as well. We have not attempted any length beyond that. We now manufacture temperature sensor extension cables
designed and tested to work with the Smart Recirculation Control family of products.
If you would like to eliminate heating up a large section of your return plumbing, you can purchase one of these extension cables
and relocate the temp sensor at the end of your recirculation loop to a location just after the last hot water fixture.
