5Pcs 77707-0010 Pool Heater Temperature Regulator for Pool & Spa Heaters — Safety Design

This 5Pcs thermal regulator kit (model 77707-0010) is a direct replacement for pool and spa heater temperature control systems. It stops the common short-cycling problem where the heater repeatedly turns on and off before reaching the set temperature, delivering steadier, more consistent water temperatures. The included thermistor has been thoroughly tested to provide dependable sensing for faster, more efficient heating. Built from high-quality metal, the regulator resists corrosion and rust — suitable for use in saltwater systems — for a durable, long-lasting solution. Engineered to install between the inlet and outlet connections on the water manifold, the unit is made specifically for pool and spa heaters. The kit comes complete with the regulator, spring, and cover so you have everything needed for a straightforward replacement and reliable operation.
