occupied mod set point if any of the of the following conditions exist: 1) if either
of the temperature adjustment buttons on the wall mount sensor/controller are
pressed the sensor will operate in occupied mode for 2 hours (setback reset), or
2) if CO
levels rise to levels greater than 50 ppm above outside levels or 3) the

controller shall also be able to receive a closed contact signal to allow control of
setback based on an external timer. A closed contact signal will indicate the
system should be in occupied mode.
