The Aquastat is a temperature‑regulating device that ensures your boiler operates within the optimal heat range for efficient heating. The Armstrong Astro 3/4" Aquastat, part **110123-121**, provides reliable set‑point control and protects equipment from overheating.
Designed with a robust housing and a compact 3/4" inlet/outlet, the Aquastat monitors water temperature through a built‑in sensor and activates the boiler heating elements when the temperature falls below the programmed low limit, then shuts off the burner once the high limit is reached.

- Accurate Set‑Point: Maintains temperature within ±2 °F of the selected limit.
- Quick Response: Activates heating within seconds of a temperature drop.
- Energy Savings: Reduces boiler cycling, lowering fuel consumption.
⚠️ Application Profile: Ideal for residential and light‑commercial hydronic heating systems, boiler retrofits, and repair projects requiring precise temperature control.
