    Haven't had a chance to use it since it works with your INSTEON THERMOSTAT that we also can't use in nearly all Florida installs.

    Great product
    HALYNA -- van nuys, CA   10/5/2012
    A bit pricey for what it is but works as advertised.
    Scott -- Virginia   8/31/2012
    The 6 foot wire is too short for use in pool or spa as wiring must be unbroken from the entry point in the water to a protected, sealed, above-ground junction box set a safe distance from the water, at which point an additional 22 gauge wire could safely be attached.

    Is this device rated as any particular class/type of thermocouple? Knowing its technical specifications as a certain type of thermocouple per would be very helpful for using this probe with other thermostats and controllers. Thanks!
