The LX and LT models include automation ready features to provide convenient pool to spa switching.  The LX's user-friendly graphic interface is a key element in your RS controlled pool/spa environment that lets you perform complete diagnostics, set precise pool and spa temperatures or switch from pool to spa mode at the touch of a button.  The LT has a simplified dual electronic thermostat.
