Looking for some help. I didn't have this issue last year, but the last few weeks I noticed my IC40 SWG show "red" no flow when I install the Thermal Regulator on the MasterTemp 250 heater and my pump speed is set to low.
I tested the thermal regulator in some hot water and it does open at 120 F. The SWG works fine on if my pump speed is set to high, but I don't run my pump on high most of the time. Any ideas? Seems like the thermal regulator or thermostat is causing enough restriction in my water flow to stop the SWG from running, and I also notice the water coming of the returns looks to be a lower flow rate.
Thanks for the help!
