Depending on the draw of the spa/pool
equipment, there are a few options available.
1.) For 240 Volt 30-amps or less:
Elk products (elkproducts.com) makes
a REALLY nice unit called the Elk 9100.
It is a self-contained X-10 compatible
30-amp double-pole relay, with built-in
signal bridge, and signal repeater.
I have it on a water heater in a remote area,
and have had NO problems with it whatsoever.
The signal bridge works great, and the
signal repeater can be disabled.
2.) For 240-volt higher than 30-amps:
Get a heavy-duty CONTACTOR (with 120-volt
coil), in an outdoor-rated enclosure.
Mount a Leviton 2250 relay module inside
the enclosure, connected to the coil.
Feed the module/coil with 120 Volts from
one phase. Neutral wire required.
For 120-volt, 20-amps or less:
Use a Leviton 2250AW relay module,
or any other similarly-rated module.
As for HVAC:
Worthington Distribution (worthdist.com)
has a model TXB16 X-10 compatible thermostat
which is compatible with standard A/C, and
Heat Pumps.
I found it too cumbersome to use for the
casual user, and it uses 1 entire house code.
(Instead, I went with the RS-232 version of
the same unit, and use remote-control
software to change the settings on the
thermostat. . .)
I hope this helps. . .
