Pentair Thermal Regulator Kit – Model 77707‑0010

The Pentair 77707‑0010 is a genuine OEM thermal regulator kit designed for use in Pentair/Sta‑Rite pool‑ and spa‑heater systems such as the MasterTemp® and Max‑E‑Therm® series.

Key Features:

Includes thermal regulator cap and spring clip for proper heater water‑system regulation
Direct replacement part—restores correct water‑temperature safety regulation inside the heater assembly
Compatible with Pentair MasterTemp and Sta‑Rite Max‑E‑Therm heaters

Technical Specifications:

Model / SKU: 77707‑0010
Application: Water‑system thermal regulation in MasterTemp / Max‑E‑Therm heater series
Includes: Regulator cap + spring clip • Stainless body components • Pre‑assembled for drop‑in replacement
Warranty: Typically 1‑year limited when installed by a professional

Maintenance Tip: Before installation, shut off power and drain the heater. Remove the old regulator cap and spring clip, clean the mating surface and inspect for corrosion. Install the new kit, ensure proper seating and spring tension, then restore water and power. Monitor water temperature and verify the heater cycles correctly. Replace the kit immediately if temperature control becomes erratic or a “HLS” (high‑limit safety) code appears.
