Pentair 472734 Control Card Set for UltraTemp and ThermalFlo Titanium

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

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

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

Complete heat pump control kit

The control board acts as the heat pump's control center. It processes information from the sensors and safety devices to manage the 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 heat pump's main components
• Parameter display on the control panel

Replacing the board may restore normal operation to an appliance with a confirmed electronic problem.

Contents of the Pentair 472734 kit

Part number 472734 corresponds to a replacement kit comprising the main components of the control interface.

Included components

• Electronic control board
• Control panel bezel or trim
• Control 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 part number 472734

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

Recommended verification

Before ordering, check:

• The exact heat pump model
• The serial number
• The year of manufacture
• The number shown on the existing board
• The connector layout
• The appliance's electrical configuration
• Compatibility with the control panel bezel

Some UltraTemp heat pumps have undergone 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 operation of the heat pump according to the selected temperature.

It contributes in particular 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 a display and diagnostic functions for monitoring heat pump operation.

When should the control board be replaced?

Replacement may be necessary when:

• The screen no longer turns on
• The buttons no longer respond
• The display is incomplete or unstable
• The heat pump no longer responds to the settings
• The displayed temperature is erratic
• Error codes persist despite checking the components
• 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 that the control board is defective. The sensors, safety devices, water flow, electrical supply, and other components must also be checked.

Professional diagnosis recommended

Before replacing the part, a technician should confirm:

• Presence of an adequate electrical supply
• Condition of the fuses and connections
• Operation of the temperature sensor
• Operation of the flow detector or water pressure switch
• Condition of the refrigeration circuit pressure switches
• Continuity of the 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 disconnect the electrical power.
2. Confirm that there is no voltage before touching the components.
3. Photograph the existing connections.
4. Identify each wire and connector.
5. Carefully remove the old board.
6. Install the new board and its bezel.
7. Reconnect the connectors to the appropriate locations.
8. Check the configuration and settings.
9. Restore power to the equipment.
10. Test the heating system and safety devices.

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