Can I wire AIRLOCK One to a variable-speed fan circuit?Updated 6 hours ago

Wire it to the blower’s AC power (the same hot/neutral or L1/L2 that power the fan), not to the variable-speed control/thermostat terminals.

This lets AIRLOCK One run when the fan runs—ideal for airflow.

If a blower feed isn’t accessible, wiring to a constant 80–240VAC source is fine, since the unit draws very little power (~1W).

As a last resort, you can wire AIRLOCK One to the most commonly used fan-speed tap so it runs whenever that speed is active.
