FUNCTION

Clock Input/Output for 2-Wire Serial Communication Port. This input should be tied to GND for

stand-alone thermostat operation.

Ground

Thermostat Output. Open-drain output becomes active when temperature exceeds TOS.

Device configuration defines means to clear overtemperature state.

Supply Voltage 2.7V to 5.5V Input Power Pin

Data Input/Output for 2-Wire Serial Communication Port. In the stand-alone thermostat mode,

this input selects hysteresis.
