HWH Auto systems use 2 relays and are DIFFERENT parameters. 1. The MASTER relay when you turn the system ON, supplies power to the SYSTEM and is built for continuous duty(HI AMP). 2. The 2nd relay is the PUMP MOTOR run relay and is designed for short duty just to run the Pump Motor. 3. DO NOT use any other relay other than the relay's that are designed for the system. Doug
