IO HVAC Controls LL Lead/Lag Controller

The Resideo L4006A1678 Aquastat is a control device specifically designed for hydronic heating systems, often integrated with boilers or water heaters. This versatile component (weighing around 1.44 lbs) can be mounted horizontally or vertically to fit various installation needs. It acts as a safety switch and a temperature regulator, ensuring efficient and safe operation of your heating system. The Aquastat continuously monitors the water temperature. When the water temperature falls below a user-set point on the adjustable control dial (ranging from 100°F to 240°F), the Aquastat activates the boiler or water heater. Once the desired temperature is reached, the Aquastat automatically shuts off the heating source to prevent overheating. This precise temperature control helps maintain system efficiency and prevents potential damage from excessively hot water.
