- NTC thermistor technology for accurate, responsive temperature sensing
- Integrated switch function for combined sensing and control in one component
- Designed for direct drop-in replacement in compatible HTP systems
- Helps maintain precise temperature regulation for optimal system efficiency and safety
- Compact design for straightforward installation in tight equipment spaces
Applications
- HTP boilers and combination heating systems
- Domestic hot water heaters and indirect water heaters
- Hydronic heating systems requiring NTC-based temperature feedback
Why Choose the HTP 7450P-281?
Using genuine OEM replacement sensors ensures your HTP system operates within factory-specified parameters. NTC sensors provide a continuous, analog temperature signal that allows the control board to make precise adjustments, improving both comfort and energy efficiency. The integrated switch function reduces wiring complexity and potential failure points compared to separate sensor-and-switch configurations.
Compatibility
- Intended for use in HTP heating equipment — consult your equipment’s parts list or service manual to confirm fitment before ordering
