About This Item

The Pentair 471587 is the OEM replacement 115°F hi-limit thermostat for the MiniMax pool and spa heater series.

IMPORTANT: LICENSED PROFESSIONAL INSTALLATION REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.

The hi-limit thermostat is a critical safety component in the MiniMax heater. It monitors water temperature and cuts power to the burner assembly if the water temperature reaches the set limit, protecting the heater and plumbing from thermal damage caused by overheating conditions.

Poolaroo Pro Tip

When replacing a hi-limit thermostat, have a qualified technician verify that the replacement part matches the original temperature rating exactly. Installing a thermostat with the wrong cut-off temperature can result in inadequate overheat protection or nuisance shutdowns. Verify the part number on the original component before ordering.

Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
