The Aquasmart5 RTA is a controller for heating a swimming pool with a solar collector and a heat pump or gas heater. Two pumps are controlled where the solar pump can be locked to the circulation pump if required for retrofit/integrated plumbing. A valve drive can be optioned in and is used instead of a solar pump (on retrofit/integrated systems) or it can be used to block thermal syphoning by using a 3-way valve. If the heating system is independent of the filtration, a 3-way valve is required to bypass or send water to the solar collector before returning to the heat-pump or gas heater.
