8402-171 OBSOLETE
- Water Temperature Limit
Bard part 8402-171 is an OEM water temperature limit control used to protect Bard HVAC equipment by monitoring water temperature and interrupting operation when temperatures move outside the safe range set by the system design. This safety device helps prevent overheating and nuisance conditions in water related heating or cooling applications where the unit relies on a controlled water loop. When replacing a temperature limit, matching the exact Bard part number is critical because sensing style, temperature setpoints, and wiring or mounting can vary by model and revision, so confirm compatibility with your unit data plate and the Bard parts list before ordering.
