Complete Guide to Converting an IntelliCenter i5P System Into a Shared Equipment Pool and Spa Automation System
Pentair IntelliCenter automation systems are among the most advanced pool automation platforms available for residential pools and spas. Many homeowners originally install a pool only IntelliCenter system and later decide to add a spa, spillover spa, water features, or additional heating controls.
One of the most common questions pool owners ask is:
“Can I upgrade my Pentair IntelliCenter from pool only to pool and spa?”
In many cases, the answer is yes.
Upgrading a Pentair IntelliCenter pool only system into a pool and spa automation system usually involves changing the system personality configuration, adding valve actuators, and properly configuring the automation panel for shared equipment operation.
This guide explains how the IntelliCenter pool to spa upgrade works, what hardware is typically required, compatibility considerations, and what pool owners should know before beginning the conversion.
Understanding Pentair IntelliCenter Pool Only Systems
Pentair IntelliCenter automation systems come in several different configurations.
Common configurations include:
- IntelliCenter i5P
- IntelliCenter i8P
- IntelliCenter i5PS
- IntelliCenter i8PS
The letter designation is important.
What Does “P” Mean?
“P” typically refers to:
- Pool only configuration
- Single body system
- No automated spa valve control
A standard IntelliCenter pool only system is designed to operate:
- Swimming pool circulation
- Pool heater
- Pool lights
- Water features
- Salt systems
- Pumps and relays
However, it may not be configured to automatically switch between pool mode and spa mode.
What Does “PS” Mean on IntelliCenter?
The “PS” designation refers to:
- Pool and Spa
- Shared equipment system
- Automated valve switching capability
A Pentair IntelliCenter PS system is designed to control:
- Pool circulation
- Spa circulation
- Shared heater systems
- Automated suction valves
- Automated return valves
- Spillover operation
- Spa heating mode
- Pool/spa temperature management
This configuration allows the system to automatically redirect water flow between the pool and spa using motorized actuators.
Can You Upgrade an IntelliCenter Pool Only System to Pool & Spa?
In many installations, yes.
Many Pentair IntelliCenter pool only systems can be upgraded to support pool and spa operation depending on the installed hardware and motherboard compatibility.
Typical upgrades involve:
- Updating the system personality
- Adding valve actuators
- Reconfiguring automation settings
- Adding spa plumbing controls
- Configuring heater automation
However, the exact upgrade path depends on:
- Existing IntelliCenter model
- Installed expansion boards
- Relay availability
- Valve outputs
- Shared equipment plumbing design
Some systems may require additional hardware kits or professional configuration.
Common Hardware Needed for a Pool & Spa Upgrade
Valve Actuators
One of the most important parts of a pool/spa conversion is adding automated valve actuators.
These actuators automatically rotate plumbing valves to switch between:
- Pool mode
- Spa mode
- Spillover mode
Typical systems require:
- One suction valve actuator
- One return valve actuator
Pentair valve actuators are commonly used for this purpose.
Shared Equipment Plumbing
Most pool and spa combinations share:
- Heater
- Pump
- Filter
- Salt system
The automation system uses actuators to redirect water flow depending on which mode is active.
For example:
Pool Mode
Water circulates:
- From pool suction
- Through equipment
- Back to pool returns
Spa Mode
Water circulates:
- From spa suction
- Through heater
- Back to spa jets
The IntelliCenter automation system controls these transitions automatically.
Personality Kit Upgrades
In some installations, converting from pool only to pool/spa may require changing the IntelliCenter personality configuration.
This may involve:
- Reprogramming system configuration
- Installing a personality kit
- Updating expansion hardware
- Enabling spa functionality in setup menus
Some Pentair IntelliCenter systems are designed with upgrade flexibility, while others may require additional control hardware depending on the original installation.
Heater Integration for Pool and Spa Operation
One major advantage of upgrading to a pool and spa IntelliCenter system is automated heater control.
The system can:
- Maintain separate pool and spa temperatures
- Automatically switch heating modes
- Prioritize spa heating
- Enable spillover operation
- Coordinate pump speeds with heating demand
This is especially useful for:
- Pentair MasterTemp heaters
- Raypak pool heaters
- Jandy heaters
- Hayward heaters
- Heat pump systems
IntelliCenter Spa Mode Features
Once upgraded, the IntelliCenter system may support:
- One touch spa mode
- Spillover mode
- Automated valve switching
- Remote spa activation
- Mobile app spa control
- Separate temperature setpoints
- Heater automation
- Water feature coordination
- Pump speed automation
This creates a much more advanced backyard automation experience.
Mobile App Control
One of the biggest benefits of IntelliCenter automation is remote control through the Pentair Home app.
After upgrading to pool and spa functionality, homeowners can often control:
- Spa heating
- Spa jets
- Lighting
- Spillover operation
- Waterfalls
- Pump speeds
- Pool temperature
- Spa temperature
directly from a smartphone or tablet.
This is one of the main reasons many pool owners choose to upgrade their existing IntelliCenter systems instead of replacing them entirely.
Important Things to Check Before Upgrading
Before converting a Pentair IntelliCenter pool only system into a pool and spa system, homeowners should verify several important details.
Existing IntelliCenter Model
Determine whether the system is:
- i5P
- i8P
- Other IntelliCenter configuration
Some systems may already support upgrade paths.
Available Valve Outputs
Pool and spa systems require actuator outputs for:
- Suction valve
- Return valve
Verify the automation panel supports these connections.
Relay Availability
Additional spa features may require:
- Extra relays
- Expansion boards
- Additional high voltage outputs
especially if the system already controls:
- Lights
- Waterfalls
- Blowers
- Landscape lighting
- Pumps
Plumbing Configuration
The pool plumbing must support:
- Shared equipment circulation
- Automated valve switching
- Spa suction and return separation
Some older systems may require plumbing modifications.
Heater Compatibility
Verify the heater supports automation integration with IntelliCenter.
Most modern heaters support:
- Fireman switch control
- RS-485 communication
- Two-wire automation control
Professional Installation Recommended
Although some experienced pool owners may perform parts of the upgrade themselves, IntelliCenter pool/spa conversions often involve:
- High voltage wiring
- Automation configuration
- Plumbing modifications
- Heater integration
- Valve actuator setup
Professional installation is usually recommended for safety and proper system operation.
Benefits of Upgrading IntelliCenter to Pool & Spa
