Query: How To DIY Remote Thermoswitch to Beat Zoomed Hygrotherm!

I made an extension for the sensor using pure copper LAN cable, LOW WATT iron, lead free solder, and 100MPH tape.I did not have to open it to access enough wire between unit and sensor to make the solder extension for the 2 wire sensor.The signal drops off after about 5 ft, but that was more than enough. I think it is actually more sensitive now and it keeps my temps well within range. You might get better signal with thermostat wire, but the low voltage around water is safer, so it's worth it to have a $40 remote thermostat for your duct fan.It is better if you program it within +/-10 degrees of where you want to be, because it's so accurate that it will turn on and off every 5 minutes if your fan works well.80-85 across the board and back-draft damper on the fan works explosively well.
