Unless you have a 24 hour circulation pump or your breaker is a 60 amp breaker then that sounds like it is operating correctly. Most spas function this way and will only heat while pump one is on. Your heater will use a lot of amperage while on so that is why when other components are turned on it will shut off so the breaker does not trip.
