Does every Armstrong Booster system come with an Aquastat?
Yes. In constant run systems, the Aquastat is connected to a solenoid bleed valve to discharge hot water if and when the pumps begin to churn and heat up the water (when there is no demand for water in the plumbing system). The Aquastat for such systems would be factory set at 120F. This bleeding of hot water is to prevent damage to the components of the booster system such as the pumps mechanical seal. For booster systems with no flow shutdown (Option X), the Aquastat is connected to the no flow shutdown circuitry of the booster controller. In such systems, there would be a booster system shutdown when the water temperature reaches a factory setting of approximately 80F. During periods of no flow, it normally takes about 5 minutes of pump churn to heat up the water to this level and thus, effect booster shutdown.
