The Watts Radiant DualTemp thermostat has the ability to sense
the temperature of the air, fl oor or a combination of air and fl oor.
Each DualTemp comes with an internal air sensor. An OPTIONAL
external 10k sensor which allows detection of fl oor temperatures may
be ordered separately. The external sensor does not have to be used if
the DualTemp is to detect air temperatures only.
