I have been working on the programming for the automatic water changes. Here is what I have come up with. Looking for any suggestions or if I missed anything here.
AWC_Ready
Fallback OFF
Set ON
If Output AWC_Mode = ON Then OFF
If Output AWC_Reset = ON Then OFF
If Output AWC_Start = ON Then OFF
If Output AWC_Fill = ON Then OFF
If Output AWC_FillTmr = ON Then OFF
If Output AWC_Drain = ON Then OFF
If Output AWC_Fill2 = ON Then OFF
If Output AWC_Fill2Tmr = ON Then OFF
If Output AWC_Drain2 = ON Then OFF
Defer 120:00 Then ON
• Fallback: OFF
• Initial Set: ON
• Conditions to Turn OFF:
• If AWC_Mode, AWC_Reset, AWC_Start, AWC_Fill, AWC_FillTmr, AWC_Drain, AWC_Fill2, AWC_Fill2Tmr, or AWC_Drain2 are ON.
• Defer: 120 minutes before turning ON.
• Function: Indicates the system's readiness for initiating the automatic water change process.
• ON State:
• System Readiness: Shows that the system is in a state where it is prepared for a new water change cycle, assuming all preconditions are met.
• Minimum OFF Period: The system is in the minimum 120-minute OFF period required for some outputs to reset.
• OFF State:
• Active Cycle or Waiting Period: When any of the listed outputs (AWC_Mode, AWC_Reset, AWC_Start, AWC_Fill, AWC_FillTmr, AWC_Drain, AWC_Fill2, AWC_Fill2Tmr, or AWC_Drain2) are ON, AWC_Ready turns OFF. This indicates that the system is currently in an active water change cycle or has not yet completed the minimum 120-minute OFF period required before initiating a new cycle.
AWC_Mode
Fallback OFF
If Output AWC_Start = ON Then ON
If Output AWC_Timer = OFF Then OFF
If Output AWC_Reset = ON Then OFF
If Master CLOSED Then OFF
• Fallback: OFF
• Conditions to Turn ON:
• If AWC_Start is ON.
• If AWC_Timer is ON.
• Conditions to Turn OFF:
• If AWC_Reset is ON.
• If Master is CLOSED.
• Function: Controls the overall mode for automatic water change.
• ON State: Activates the water change mode, allowing filling, draining, and timing operations to proceed.
• OFF State: Deactivates the water change mode, stopping all associated processes if conditions are not met.
AWC_Timer
Fallback OFF
Set OFF
If Output AWC_Start = ON Then ON
If Output AWC_Fill = ON Then ON
If Output AWC_Drain = ON Then ON
If Output AWC_Fill2 = ON Then ON
If Output AWC_Drain2 = ON Then ON
Defer 012:00 Then OFF
• Fallback: OFF
• Initial Set: OFF
• Conditions to Turn ON:
• If any of AWC_Start, AWC_Fill, AWC_Drain, AWC_Fill2, or AWC_Drain2 are ON.
• Defer: When transitioning to OFF, the change is deferred for 12 minutes. If any of the specified outputs (AWC_Start, AWC_Fill, AWC_Drain, AWC_Fill2, or AWC_Drain2) turn back ON during this defer period, the 12-minute counter resets. The defer period is set 1 minute longer than the longest time between filling and draining cycles to ensure accurate detection of all cycle completions.
• Function: Manages the timing for automatic water change operations, including soak periods between filling and draining.
• ON State:
• Deactivation of Defer: The defer timer to turn OFF begins only when none of the water change outputs are ON. If any of these outputs turn ON again during the defer period, the timer resets.
• Cycle Completion: Ensures accurate timing for filling, draining, and soak periods.
• OFF State:
• Process Completion: Indicates that all water change operations and soak periods are complete. Once the defer period concludes and the output turns OFF, AWC_Mode is deactivated, signaling the end of the water change cycle.
AWC_Reset
Fallback OFF
Set OFF
If SW_AWC CLOSED Then ON
Defer 000:05 Then ON
Defer 002:00 Then OFF
• Fallback: OFF
• Initial Set: OFF
• Conditions to Turn ON:
• If SW_AWC is CLOSED.
• Defer: Turns ON after 5 seconds, then OFF after 2 minutes.
• Function: Resets the system to its initial state, clearing current operations and setting conditions to default.
• ON State:
• System Reset: Initiates a system reset, which turns OFF AWC_Mode. This action in turn turns OFF all associated cycles and operations, such as AWC_Start, AWC_Fill, AWC_Drain, AWC_Fill2, AWC_Drain2, etc.
• Interaction with Other Outputs:
• AWC_Mode: When AWC_Reset is activated, it turns OFF AWC_Mode, which deactivates all water change cycles and processes controlled by this output.
• Minimum 120-Minute OFF Period: Since AWC_Mode turns OFF all other cycles, if any of these outputs were ON before the reset, they will need to meet their minimum 120-minute OFF period before being reactivated. This OFF period ensures that the system has enough time to complete the cycle before starting a new one.
• OFF State:
• End of Reset Process: Marks the completion of the reset process, allowing the system to return to its normal operational state.
• Resumption of Normal Operations: Once AWC_Reset turns OFF, the system will need to adhere to the minimum 120-minute OFF period for any previously active cycles before resuming normal operation. AWC_Mode and other outputs will only be ready for activation once this period has elapsed.
AWC_Start
Fallback OFF
Set OFF
If SW_AWC CLOSED Then ON

• Minimum Time: When AWC_Start turns OFF, it must remain OFF for at least 120 minutes before it can be turned back ON.
• Function: Initiates the automatic water change process by controlling related outputs.
• ON State:
• Turns ON AWC_Mode: Activates AWC_Mode, which manages the overall water change process and coordinates other related outputs.
• Starts AWC_Fill: Initiates the filling process by turning ON AWC_Fill.
• Manages Other Outputs: Ensures that other outputs related to the water change process are kept off or controlled as defined by their conditions and timing requirements. Specifically:
• AWC_FillTmr, AWC_Fill2, AWC_Fill2Tmr, AWC_Drain, AWC_Drain2, and others may be kept in their respective OFF states or controlled according to their conditions.
• OFF State:
• Does Not Disrupt Ongoing Processes: Turning OFF AWC_Start stops the initiation of new cycles but does not affect the filling or draining operations already in progress. The output must remain OFF for at least 120 minutes before it can be reactivated, ensuring a proper off-period before any subsequent activation.
