Planning on putting a controller on our solar system. House is ~75' from equipment pad so the 15' 20GA wire that seems typical for the temperature sensor is obviously not going to work.
In the Hayward manual I see the note "For long runs or runs near other electrical wiring use shielded cable (Belden 8428 for outdoor use)". A quick Google reveals that 8428 is a shielded 18GA twisted pair typically used for audio microphones and a 100' length is > $300 That seems a bit excessive for a $20 sensor. Unfortunately, there is really no good place closer to the pad.
I understand that there is more resistance as the wire gets longer but is this really necessary?
Does anyone out there have a sensor run close to 100' and what kind of wire are you using?
