Figure 4-4. Input Properties for Compare Operation
4. Add an output to the equation. Set its Opcode and Qualifier to the
following:
• The Opcode must be one of the following: Set Threshold Photo, Set
Threshold Ion, Set Threshold Heat, Set Threshold XPHOTO.
• The Qualifier is the threshold that you want to set. For example,
Smoke Level 2.5.
As shown in the figure below, the second equation is programmed almost
exactly as the first equation. Its Input Qualifier monitors A11 (current hour) to
determine when it is equal to 18 (6:00 p.m.). At 6:00 p.m., the smoke level is
changed to 1.0.
