## Summary description

ACV NTC3 temperature sensor (model 786491) is designed for monitoring domestic hot water (c.w.u.) temperature. It uses an NTC thermistor to provide temperature-dependent resistance for integration with boilers, water heaters and control systems. Suitable for replacement or installation where an NTC3-type probe is required to measure and relay hot water temperature for control and safety functions.

## Long description

The ACV temperature sensor NTC3 for domestic hot water (c.w.u.) — model 786491 is an NTC thermistor probe designed to monitor the temperature of potable hot water systems. Intended for use with boilers, water heaters and control units, this sensor converts temperature changes into a corresponding resistance signal used by controllers to regulate heating, maintain setpoints and support safety interlocks. The compact probe form factor fits common sensor ports and is suitable for replacement or new installations where an NTC3-type sensor is specified.
Advantages
This ACV NTC3 sensor offers accurate temperature-dependent resistance output and is optimized for integration with domestic hot water systems. Its design provides reliable readings over typical hot water temperature ranges and allows straightforward wiring into compatible control circuits. The probe's construction supports routine replacement and helps maintain correct system operation for temperature regulation and safety functions.
Suitable for
Monitoring domestic hot water temperature in residential boilers and water heaters
Replacement of existing NTC3-type temperature probes
Integration with heating control units and safety systems
Use in systems that require NTC thermistor input for temperature regulation
Key specifications
Sensing element type: NTC thermistor
Application: domestic hot water (c.w.u.) temperature measurement
Form factor: probe suitable for insertion into standard sensor ports
Output: temperature-dependent resistance signal for controller input
Compatibility: designed for use with boilers, water heaters and control systems supporting NTC3 probes
How to use
Install the sensor into the designated sensor port or pocket on the boiler or water heater, ensuring good thermal contact with the medium. Connect the sensor leads to the controller or thermostat input configured for an NTC thermistor, observing correct polarity if applicable and securing connections to prevent corrosion or loosening. After installation, verify sensor readings via the control unit and perform any necessary calibration or configuration so the controller interprets the resistance values correctly for temperature regulation and safety thresholds.
Usage recommendations
For reliable operation, mount the probe in the recommended location within the hot water circuit to ensure representative temperature measurement, avoid direct exposure to high-velocity water jets, and protect the wiring from mechanical damage and moisture. Replace the sensor if readings become unstable or inconsistent, and consult the equipment manual for controller-specific input settings when integrating the NTC3 sensor.
