Product Specifications

Compatibility - Important Before Ordering

This sensor is identified for Softub P5 through P8 systems.

Compatible equipment generations may include:

• Softub P5

• Softub P6

• Softub P7

• Softub P8

Compatibility should be confirmed using the existing sensor part number, connector, and equipment configuration.

Do not assume this sensor is compatible with P9 or other Softub control systems.

Before ordering, confirm that your existing part matches SKU 2027 and that the fault has been properly diagnosed.

Signs of a Possible Temperature Sensor Problem

A faulty temperature or high-limit sensor may be associated with:

• Incorrect or inconsistent temperature readings.

• Temperature-related error indications.

• Unexpected heating interruptions.

• High-limit safety shutdowns.

• Intermittent operation associated with the temperature monitoring circuit.

These symptoms do not necessarily mean the sensor is defective. Low water flow, overheating, wiring faults, control problems, or other equipment issues can cause similar behaviour.

Installation & Safety

Professional installation is strongly recommended.

The temperature and high-limit system is an important part of your spa's heating safety controls.

Before servicing, the technician should:

1. Disconnect the spa completely from electrical power.

2. Confirm the correct replacement sensor and connector configuration.

3. Diagnose the cause of the temperature-related fault.

4. Install the sensor following the applicable Softub service documentation.

5. Inspect wiring, connectors, and related components.

6. Verify temperature monitoring and high-limit safety operation before returning the spa to service.

Never bypass a high-limit sensor or other temperature safety device to keep the spa operating.
