Pentair 472734 Control Card Set for UltraTemp and ThermalFlo Titanium

Restore the operation of your pool heat pump with thePentair control board kit 472734. Designed for certain Pentair UltraTemp and ThermalFlo Titanium heat pumps, this kit allows replacement of a defective, damaged, or unstable electronic control.

Part 472734 includes the electronic control board, control panel face, and corresponding label. It manages temperature and communication with several essential heat pump components.

Pentair lists this reference under the official description Bezel, Control Board & Label Kit in the UltraTemp replacement parts list.

Complete control kit for heat pump

The control board acts as the command center of the heat pump. It processes information from sensors and safety devices to manage heating sequences.

Main functions

• Water temperature management
• Control of heating cycles
• Communication with sensors
• Monitoring of safety devices
• Management of messages and diagnostic codes
• Coordination of the main heat pump components
• Display of parameters on the control panel

Replacing the board can restore normal operation of a device with a confirmed electronic issue.

Contents of the Pentair 472734 kit

Reference 472734 corresponds to a replacement kit including the main components of the control interface.

Included components

• Electronic control board
• Control panel face or bezel
• Control panel identification label

Sensors, wiring harnesses, relays, contactors, and other internal components are sold separately unless otherwise indicated.

Compatibility

This kit is intended for certain Pentair pool and spa heat pumps.

Indicated compatibility

• Certain Pentair UltraTemp heat pumps
• Certain Pentair ThermalFlo Titanium heat pumps
• Installations using Pentair reference 472734

The current Pentair documentation lists part 472734 in the UltraTemp replacement parts section.

Recommended verification

Before ordering, check:

• The exact model of the heat pump
• The serial number
• The year of manufacture
• The number printed on the existing board
• The arrangement of connectors
• The electrical configuration of the device
• Compatibility with the control panel

Some UltraTemp heat pumps have had component changes depending on their year of manufacture. Validation using the serial number is therefore recommended.

Precise temperature management

The electronic board receives data from the water temperature sensor and controls the heat pump operation according to the selected temperature.

It notably contributes to:

• Maintain the programmed temperature
• Start or stop heating
• Display operating parameters
• Detect certain anomalies
• Protect the system when conditions do not allow safe operation
• Communicate with compatible equipment

UltraTemp systems have an electronic control with display and diagnostic functions to monitor the heat pump's operation.

When to replace the control board?

Replacement may be necessary when:

• The screen no longer lights up
• The buttons no longer respond
• The display is incomplete or unstable
• The heat pump no longer responds to settings
• The displayed temperature is erratic
• Error codes persist despite component checks
• The board shows signs of corrosion or overheating
• Electrical damage is visible
• A technician has confirmed an electronic failure

A heat pump that no longer works does not automatically mean the control board is defective. Sensors, safety devices, water flow, power supply, and other components must also be checked.

Professional diagnosis recommended

Before replacing the part, a technician should confirm:

• Presence of an adequate power supply
• Condition of fuses and connections
• Operation of the temperature sensor
• Operation of the flow detector or water pressure switch
• Condition of the refrigerant circuit pressure switches
• Continuity of electrical harnesses
• Absence of corrosion or water infiltration
• Compatibility of the new board

This check reduces the risk of unnecessarily replacing a still functional board.

Installation by a qualified technician

Installing the Pentair 472734 assembly requires opening the heat pump's electrical compartment.

Important recommendations

1. Completely cut off the power supply.
2. Confirm the absence of voltage before touching the components.
3. Photograph existing connections.
4. Identify each wire and connector.
5. Carefully remove the old board.
6. Install the new board and its front panel.
7. Reconnect connectors to the appropriate locations.
8. Check configuration and settings.
9. Power the device back on.
10. Test the heating and safety devices.

Installation must be performed by a qualified technician familiar with Pentair pool heat pumps. Incorrect wiring can damage the board or other electrical components.
