Laars Heating Systems FT1861 Communicate Cable Cascade

The Laars Heating Systems FT1861 Cascade Communicate Cable is a structural interconnection component used in modular boiler systems to enable communication between multiple units operating in a configuration. It transmits control signals that allow boilers to coordinate firing stages and share load demand within a connected heating network in HVAC systems applications. It ensures synchronized operation of boilers for stable system performance. Installed between each boilers control board, it links the lead unit to follower units so the cascade controller can regulate temperature output efficiently across the system.
