## Long description

Temperature Sensor for Domestic Hot Water INSIZE P0431 KTF20 is a compact immersion probe designed to measure and monitor hot water temperature in residential and commercial installations.

Routine maintenance checks and system diagnostics
Key specifications
Type: Immersion temperature probe for domestic hot water
Measurement medium: Hot potable water and circulating heating water
Probe design: Compact cylindrical probe suitable for sleeve or direct immersion
Compatibility: Designed for integration with heating controllers, boiler systems and circulation pumps
Typical installation environment: Domestic and light-commercial hot water systems
How to use
Install the probe in a dedicated sensor pocket, immersion sleeve or secure it directly in the flow/return line where permitted by system design. Connect the sensor wiring to the control unit following the controller manufacturer’s connection diagram and ensure proper polarity where applicable. Allow the system to stabilise after installation and verify displayed temperature values against a reference thermometer if accuracy check is required. Tighten fittings and confirm there are no leaks in the sensor mounting area before returning the system to normal operation.
Usage recommendations
Place the sensor where representative flow temperature is available and avoid mounting immediately adjacent to heat sources that do not reflect bulk water temperature. Where possible, use a protective sleeve for easier replacement, and follow the heating system manufacturer’s guidelines for sensor placement and wiring to ensure accurate control performance and long-term reliability.
