ScreenLogic2 Delays and Alerts Reference
The ScreenLogic2 Delays & Alerts screen displays the current delays and alerts for the system. The system water and air sensors are constantly monitored for errors. If a sensor error is detected, it is displayed in the Alerts section. This reference covers the exact message names used by the ScreenLogic2 interface and what each means.
Delays vs. Alerts: The Key Distinction
These two message categories have fundamentally different implications:
Delays
A delay is a normal operational state. The system is functioning as programmed and is temporarily holding off on a circuit change to protect equipment or allow safe transitions. No action is required from the technician or homeowner — the delay will clear automatically when the condition is resolved. From the Delays & Alerts screen, the Cancel Delays button can cancel the following safety delays on a one-time basis (for service or testing):
- Cleaner On Delay
- Pool Off Delay
- Spa Off Delay
Alerts
An alert indicates an abnormal condition that requires attention. The system has detected something outside normal operating parameters. The alert is displayed in yellow in the Alerts section of the Delays & Alerts screen and in the System Status box on the Equipment screen.
How to Access the Delays and Alerts Screen
In the ScreenLogic2 Interface (App or PC)
- From the main ScreenLogic2 Interface screen, tap the Equipment tab
- The error message is displayed in the System Status box. If there are multiple errors, they are cycled in the status box
- For the full Delays & Alerts view, navigate to the Delays & Alerts screen
System Alert Messages (Temperature Sensors)
The system water and air sensors are constantly monitored. If a sensor error is detected, the following messages display exactly as shown below:
| Message | Type | Meaning | Action |
|---|---|---|---|
| Pool Water Temp Sensor | ALERT | The pool water temperature sensor is reading outside its valid range or is disconnected | Check the sensor wiring at the sensor body and at the load center sensor input terminals. Test sensor resistance and replace if out of spec. A failed pool water temp sensor will disable heater operation for the pool |
| Pool Solar Temp Sensor | ALERT | The pool solar temperature sensor is faulty or disconnected | Check the solar sensor wiring. If solar heating is not installed, verify this circuit is not incorrectly configured as "Solar Present" in the Configurator utility |
| Air Sensor | ALERT | The air temperature sensor is reading outside its valid range or is disconnected | Check air sensor wiring. A failed air sensor will prevent accurate freeze protection operation — the system may trigger freeze protect unexpectedly or fail to trigger it when needed |
| Spa Water Temp Sensor | ALERT | The spa water temperature sensor is faulty or disconnected | Check the spa sensor wiring. A failed spa water temp sensor will disable heater operation for the spa |
| Spa Solar Temp Sensor | ALERT | The spa solar temperature sensor is faulty or disconnected | Check the spa solar sensor wiring and configuration |
IntelliFlo Pump Alert Messages
When an IntelliFlo pump alarm is detected, the message displays in the pump status panel. Messages appear in the format "Pump 1: [condition]" (or Pump 2, Pump 3, etc.):
| Message | Meaning | Action |
|---|---|---|
| Pump 1: Filter Warning | Filter differential pressure has reached the clean filter pressure setting — filter needs cleaning or backwashing | Stop IntelliFlo, place IntelliTouch in Service mode, then run backwash cycle. After backwash, run Rinse cycle |
| Pump 1: Drive Temperature Warning | Excessive drive temperature — pump will slow down to reduce heat | Ensure the motor fan has adequate ventilation clearance. Allow motor to cool. Run motor at a higher speed to improve cooling air flow |
| Pump 1: Priming Alarm | Pump could not achieve prime within the Max Priming Time setting. Pump will stop for 10 minutes then retry. After five failed attempts, a permanent alarm requires manual reset | Check for air in the system, verify strainer basket and lid are sealed, check suction valves are open |
| Pump 1: System Blocked Alarm | A blocked suction line was detected. Pump shuts off immediately and restarts automatically after 30 seconds | Inspect suction lines and strainer basket for obstruction. Check for blocked drain covers |
| Pump 1: Unknown Alarm | Electronic failure in the pump drive (LED blinks 5 times) | Cycle power to reset pump. If alarm persists, replace the pump drive |
| Pump 1: Drive Temperature Alarm | Excessive drive temperature — pump has stopped (LED blinks 6 times) | Ensure motor fan has ventilation clearance. Run motor at a higher speed to improve cooling air flow after motor cools |
| Pump 1: Power Outage Alarm | Supply voltage is low — less than 170 VAC (LED blinks 7 times) | Check the supply voltage and wiring for voltage drop |
| Pump 1: Over Current Alarm | Drive is overloaded or motor has an electrical problem. Drive restarts 20 seconds after condition clears (LED blinks 8 times) | Examine the fluid and mechanical system for source of overload. De-energize motor and verify it spins freely. Replace drive if problem persists |
| Pump 1: Over Voltage Alarm | Excessive voltage on the drive's internal DC bus. Drive restarts 20 seconds after condition clears (LED blinks 9 times) | Check supply voltage. Rapid speed switching between speeds can cause this condition |
| Pump 1: Communication Lost | The ScreenLogic2 system has lost communication with the IntelliFlo pump | Check the RS-485 wiring between the pump and the load center. Verify polarity. Power-cycle both devices |
IntelliChlor (SCG) Alert Messages
When an IntelliChlor salt chlorine generator error is detected, the message displays in the format "SCG: [condition]":
| Message | Meaning | Action |
|---|---|---|
| SCG: Low Flow Error | IntelliChlor is detecting insufficient water flow through the cell | Check that the pump is running. Check for clogged filter or restricted flow. Check flow switch |
| SCG: Low Salt Level | Salt concentration is below the recommended operating level | Test water with independent test kit and add salt as needed to reach 3200–3500 ppm |
| SCG: Very Low Salt | Salt concentration is critically low — cell output is reduced or stopped | Add salt immediately. Verify reading with independent test kit |
| SCG: High Current | Cell is drawing excessive current | Inspect cell for scale buildup. Clean cell with diluted acid solution per IntelliChlor manual |
| SCG: Clean Salt Cell | Cell needs cleaning — scale has accumulated on electrode plates | Remove cell and clean with diluted muriatic acid (1:4 ratio) per IntelliChlor manual |
| SCG: Low Voltage | Voltage to the cell is below normal operating range | Check the power supply to the IntelliChlor control box and wiring connections |
| SCG: Communication Lost | The ScreenLogic2 system has lost communication with the IntelliChlor controller | Check the communication cable between the IntelliChlor and the load center. Verify polarity. Power-cycle the IntelliChlor |
IntelliChem Controller Alert Messages
When an IntelliChem water chemistry controller error is detected, messages display in the format "pH/ORP: [condition]":
| Message | Meaning | Action |
|---|---|---|
| pH/ORP: No Flow | IntelliChem is not detecting water flow — chemistry dosing is suspended | Verify the pump is running and flow switch is operational. Check for obstructions in the chemistry feed line |
| pH/ORP: pH Reading Too High | pH probe is reading above the expected range | Test pH with manual test kit. If accurate, add acid to lower pH. If reading appears incorrect, clean or replace the pH probe |

| pH/ORP: pH Feed at Limit | pH dosing has reached the maximum daily feed limit | Review pH set point and water chemistry. Check for a pH swing condition and adjust accordingly |
| pH/ORP: ORP Feed at Limit | ORP dosing has reached the maximum daily feed limit | Review ORP set point and chlorine demand. Check for factors driving high chlorine consumption |
| pH/ORP: Communication Lost | The ScreenLogic2 system has lost communication with the IntelliChem controller | Check the RS-485 communication cable between IntelliChem and the EasyTouch load center. Verify polarity. Power-cycle both devices |
About the Heater Cool-Down Delay
The ScreenLogic2 system includes an optional heater cool-down delay feature ("Pump on during heater cool-down") that can be configured in the Configurator utility under Configure Other Equipment (Step 3 of 5). When enabled, this keeps the filter pump running for ten minutes after the heater goes off to dissipate residual heat built up inside the combustion chamber.
⚠ Pentair Heaters Do Not Require This Delay
Heaters manufactured by Pentair Water Pool and Spa do not require this cool-down period and do not need the delay to be set up. The cool-down delay feature is intended for non-Pentair heaters that specify a cool-down requirement.
The Cancel Delays feature in the Delays & Alerts screen allows a service technician to cancel the heater cool-down delay on a one-time basis — shutting the filter pump off immediately. There is generally not a need to cancel any delays except for servicing or testing the system.
