A reliable timer built for hydronic boiler systems ensures precise start‑stop cycles and protects equipment from overheating. The 110223B-245 Armstrong Astro 225SSU‑T provides a stainless‑steel union body with integrated timing control for seamless installation and long‑term durability.

The timer operates via an adjustable mechanical clock mechanism that can be set to the required on/off intervals. When the programmed time elapses, the internal switch opens or closes the union connection, delivering accurate cycle control without the need for external controllers.

Key System Performance Baselines:

  • Timer Accuracy: Maintains ±1 second per hour for dependable cycle timing.
  • Corrosion Resistance: Full stainless‑steel construction resists moisture and chemical exposure.
  • Easy Installation: Union fitting simplifies pipe connections and reduces labor time.
  • Wide Temperature Range: Operates safely from –20 °F to 250 °F.

⚠️ Application Profile: Commercial hot‑water boilers, residential hydronic heating loops, steam‑trap timing, and industrial process heating applications.
