As this is the only input to this logic block, change the logic block type to OR, as follows:
Figure 65: Select OR function
Add any ON or OFF delay timers (if required).
Now ensure that the relevant relay output is enabled:
Figure 66: Enable Fan Output
Using the above example, the following sequence of events should now occur:
•
When Temperature1 reaches 25 deg C, the fan connected to Output 1 should switch on.
•
When Temperature1 drops to 20 deg C, the fan should switch off, and not switch on again until the
temperature returns to 25 deg C.
As previously mentioned, for Temperature Lower Hysteresis , the procedure is the same as above, but using
Temperature Lower Hysteresis as a logic input.
