Resideo - Honeywell Home 123869A Aquastat Sensor Well Assembly

Resideo - Honeywell Home 123869A Aquastat Sensor Well Assembly is engineered for reliable immersion-type temperature sensing in boilers and hydronic systems. This copper sensor well delivers precise readings with a 3/8 inch bulb diameter and 3 inch length, paired with a 1/2 inch threaded connection for flexible installation alongside compatible control panels. The immersion design provides rapid response to temperature changes, helping your system maintain consistent operation and efficient energy usage. Its copper body ensures solid heat transfer and durability in harsh heating environments.

With an insulation depth of 1-1/2 inches, it minimizes heat loss and stabilizes measurements in high-temperature environments. The assembly is designed to withstand demanding service, featuring a pressure rating of 255 PSI at 300°F and robust construction that resists vibration and thermal cycling. This Aquastat Sensor Well Assembly is ideal for replacing worn wells or configuring new installations in residential or light commercial heating setups.
