Description |
|---|---|
|
Activation |
In a low to high Input transition, the Output becomes active the next time the logic executes (logic executes every 5 seconds). Goes inactive in a high to low Input transition, depending on the state of the input during the duration period. If the Input returns to a high state (active), the timing cycle is canceled and the Output remains active. If the Input remains in a low state, the Output goes to the low state at the next execution of logic. |
|
Output |
See row above. |
|
Reset |
Cancels timer activity and makes the output inactive. If the Reset goes from active to inactive, the timer re-evaluates the Input at the next low to high transition. |
|
Example |
Keeps the fan running to purge the coils after a heating or cooling system is turned off. Off Delay is useful when your building contains electrical heat and/or DX cooling. |
