Here's a simplified look at common connections you might find on a Honeywell Aquastat L4006a, though your specific model's diagram may vary:
| Terminal Label | Typical Function |
|---|---|
| T (or 1) | High Limit - Connects to the burner control circuit. |
| T (or 2) | High Limit - Connects to the burner control circuit. |
| A (or 3) | Low Limit/Circulator Control - Often connected to the circulator pump or the low limit function. |
| A (or 4) | Low Limit/Circulator Control - Completes the circuit for the low limit or circulator. |
The exact wiring configuration will depend on whether the aquastat is being used as a high limit control, a low limit control, or both, and how it interacts with other components like thermostats and circulator pumps.
