| + | [title] Final Testing |
|---|---|
| + | [* black] Reverse the order of testing: |
| + | [* black] Connect the air proving switch and verify voltage at pins 1 & 4. |
| + | [* black] Connect the transformer and verify 24VAC out when energized and the air proving switch is cold. |
| + | [* icon_caution] DO NOT USE OR MEASURE THE HIGH VOLTAGE BOARD WITH ANYTHING OTHER THAN NON CONTACT VOLTAGE PROBE. |
| + | [* black] With everything connected, powered up the unit and watched the indicator come on and go off. I turned on the fan to the air unit and the indicator came back on and very carefully bringing the voltage probe near the HV lines, I got some nice chirping. |
