Also why cut the wires. Just unplug the connection from the board and test with your meter leads.

Right like it matters but I low key have OCD thing bothers me lol

Yes, thats true. I know what you mean. Much better to unplug the sensor and add a resistor there.

Reliatel has the temperature for each sensors . Unplug from the module and test , note : should have 5 vdc at pins with no sensor .

Short the test 1 and test 2 terminals ont the lvtb it will step through all operations including economiser. No need to fake a 50F outdoor air temp.

Because he's testing the logic module in addition to the damper motor. Jump testing with the terminals doesn't tell you anything about the logic module, only that the damper motor works. These are installed incorrectly so often that it's very important to thoroughly test all the way through rather than just trust the test terminals.

thanks this is what i like, cross reference, please keep them coming.
could you use that tester on the tstat that uses 24v but wires as 1-11 molex plug on the main board to be able to test for heat or cool without messing with the tstat's program?

Hi 👋 there good video by the way what’s the name of that tool you checked the sensor ohms. And where to buy it 😅😊
@building-automation11 ай бұрын
That is a fieldpiece multimeter. You can find them all over the internet. Amazon...I like the one with the magnet on the back, it makes life so much easier.

Can someone answer this question. Thank you in advance

I made it from a 20k potentiometer and four 20k resistors. The switches add 20k resistors into the circuit. You can actually just buy a 50k potentiometer and use it. That way you dont have to build a box.

Sir where do you get that ohm box???
@building-automation3 ай бұрын
I built it, but you can just order a 30k ohm potentiometer.

Howdy, where can I get a box like that to fake out the board?

I built that resistor bank, but you can buy a potentiometer online that will do the same thing, and just attach leads to it by soldering, crimping, or just using alligators clips.

Why did you cut the wires 🫤
@building-automation3 ай бұрын
I was simulating an outside air temperature so I could observe the economizer logic in action, but yes i suppose I could have put my resistor where the outside air temperature sensor connects to those wires by just unplugging the sensor and putting the resistor in place. It would have been cleaner that way.

A 30 turn potentiometer is a good choice. Get a nice big one, like 50k ohm or bigger.
