Comments about 1/2" Clip-On Thermostatic Control for Grundfos UP Series Circulators:

I use this thermostatic control on domestic hot water re-circulation pump to limit the return temperature to not more than 115 degrees. Used in conjuction with an indirect water heater with 145 degree water storage and mixing valve. This turns the pump off when the re-circ water reaches 115 degrees.

It is a cheap way to get some regulation in the re-circulation system.

    Q:

    Can this control be used with a zone valve on 24 volt instead of a pump on 120 volt?

  • 3/4" Clip-On Thermostatic Control for Grundfos UP Series Circulators

    Q:

    Is there a way to tell if this thermostatic control (595657) is still functioning properly? I've had it for 6+ years and now it seems that the circulation pump runs continuously. The copper pipe it's clipped to is hot and the hot water heater is set on "C", which is considered 150 degrees. That's well over the temperature in which the thermostat is suppose to shut the pump off.

      A:

      The best way I've found is to use a continuity tester (electrical) or a digital multimeter with continuity check. These tests are done with the power off!! Expose the 2 wire leads that come from the t-stat control. Above temperature there should be no continuity between the wires (switch is open). Below temperature there should be continuity between the wires (switch is closed). Remove the t-stat control from the pipe and allow it to cool - check for continuity, there should be if the device is working correctly. Warm the device with a heat gun or hair dryer. At some point, the device should "open up" (lose continuity) if the device is working correctly. Sounds like your device is no longer "opening up". Hope this helps. Good luck.

    Q:

    Does this switch turn on only between 105 and 115 degrees? For instance if the water in the pipe is heated to 150 degrees does the switch stay on until the boiler shuts off and it cools down below 115 degrees?

      A:

      The switch turns the circulator off as soon as water temperatures reach 115°F. It does not turn the circulator back on until they fall to 105°F.

    Q:

    Can you get this clip-on thermostat that connects to the UP 15-10 SU7P TLC with a 3/4" clip. My pipe is 3/4" coming out of the water heater.
