Line voltage wiring (including ground wire not shown) must meet local code.

A 24 vac transformer and relay are needed when controlling a line voltage
load with an L2. Resideo offers single-pole and double-pole R8222 relays.
Verify switch rating meets load of line voltage device.

If line voltage device should be deenergized when water leak is detected
and energized when a water leak is not detected, use 2 on a SPDT relay
rather than 3.
