Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
I don't understand your readings either since we routinely use 18 ga solid (not stranded not shielded) cable and have never had an issue. Since the manufacturer recommends 20 ga stranded pair then you should go with that. 20 gauge stranded is used for speaker wire. However it and just about any 20 ga wire is not UV rated so it will break down in sunlight. So run it so it's not in the sun
I can't address the display readout anomaly. After you install the type of wire the manufacturer recommends, if you still have a problem then it sounds like a warranty issue that you need to take up with them. We use Resol controllers and haven't had any problems with them.
We don't have an electrical engineering category only an electrical category where you'll get an electrician not an engineer. I can ask the mods to move it to electrical if you like.
Ok, please be patient it may take a while. Please don't respond until one of us gets back to you.
Hello, Welcome to JA/Pearl my name is***** and I will try to assist you today.
I have the better part of 20 years as a commercial electrician and about a year of electronics engineering classes under my belt, and I 'll try to give you some insight with what I know of low voltage installations such as the one you have.
The likely cause of poor sensor operation is in most cases EMI noise on the line either end of the circuit could be contributing to it.( possibly the sensors themselves interfering with each other) Generally, in commercial buildings, to remove any form of EMI from the equation engineers spec twisted pair cable or twisted pair shielded cable to be installed properly by the contractor ( properly grounding the shield in one location as well as continuing the shield throughout the entire installation.
So to answer which is the best for your problem I would run the recommended #AWG from the manufacturer in a twisted / shielded solid conductor for a permanent installation or stranded if you feel the solid cable could become damaged. Multiple low voltage wire manufacturers on the market like Belden brand although they can be very expensive. I would definitely shop around.
Let me know if that answers you problem, this thread will remain open for some time, Please do not forget to rate me if you are satisfied with my answer. Thank you for using JA/Pearl , and have a wonderful day.
