HVAC CONTROLS HVAC TROUBLESHOOTING

9 VOLTS battery to power this electric duct heater. because part of the controls circuit runs on 0 to 10VDC . #d2dnyac #hvac #commercialhvac

It's amazing you're able to show us those very unique techniques thanks for another great video

[@D2DNYAC]

Thanks for watching

This is why i bought an oscilloscope to see what everything is doing. An oscilloscope has become a valuable tool. It takes awhile to learn how to use its functionality. I definitely no master of it, but the more i learn the more the information has become valuable

[@D2DNYAC]

How to troubleshoot hvac controls with it?

[@jasonjohnsonHVAC]

Also you should get a signal generator. I have one and its not something i use everyday......but I use it enough to make it worthwhile to own. They are relatively inexpensive

Thanks

Good video

Thanks for watching

Very cool,also very smart so if it works that way u know the heaters are ok,

[@D2DNYAC]

Yes sir 0 to 10 volts DC is needed to control this heater so if you don't have a DC power supply/ controller. Do this for testing and temporary operations

[@Ariff-zt2gc]

Does this method of testing apply to other type of SCR as well like Thyristor/Diode Module (Powerblock) Type and Puck Type SCR ? So can apply the battery voltage to fire the gate in order to on the SCR ?

[@D2DNYAC]

Possible however you would need to know the gate voltage range

[@jasonjohnsonHVAC]

The puck style needs downward pressure to enable the gate to fire

It’s Sunday do u ever take a day off based on your videos always working

[@D2DNYAC]

When you are in high demand 😂

[@rfvedcwsxqaz9]

0-10 vdc control

[@D2DNYAC]

Yes sir
