''' Update the thermostat state based on the measured temperature.
If the measured temperature is below the lower threshold (setpoint - deadband/2),

If the measured temperature is above the upper threshold (setpoint + deadband/2),
the thermostat turns OFF (state=0).
If the measured temperature exceeds the safety_high limit, the thermostat turns OFF.
