Hello all! This is probably simple to all of you, but is confusing me as a novice! I am an HVAC technician and I built a training board using multiple thermostats. They are powered by a 24VAC transformer. When the thermostats respective switch closes, it is wired so that each respective lamp lights. Very simple circuitry! My issue is when the circuits are not closed. The LED lamps are all dimly lit. I want them to be non-powered however, they are receiving power somehow. I suspect a low voltage trickling through the solid-state thermostat boards? I’ve tried All value of resistors between the switch and the LED lamp without success, is there a different type of LED I should be using? I used this from Amazon:
DMWD 12V-24V 20mA Energy Saving LED Indicator Light Mounting Hole 6mm.
Thanks in advance!!
