Start by identifying whether you need a residential or commercial system. Residential customers should then determine whether the home has a dedicated hot-water return line and approximate home size. If you’re unsure about any of these details, contact us before ordering and we’ll help identify the correct system.

Complete systems contain the primary components needed for a specific D’MAND application. Accessories add activation or installation capabilities, while replacement parts are intended to service or modify compatible existing systems. Review the product description carefully or contact us if you’re replacing an older Metlund® or D’MAND component.

ACT2 configurations are designed for many residential applications up to approximately 4,000 ft². SS3-200 configurations are intended for larger homes or longer plumbing runs, with the appropriate version depending on whether a dedicated return line is present.

D’MAND offers separate activation and Bluetooth accessories for compatible systems. Compatibility can depend on the age and model of your existing equipment, so verify the product description or contact ACT before ordering an accessory.

D’MAND Kontrols® was formerly Metlund®, but replacement compatibility depends on your specific model and generation. Contact ACT with the model information from your existing system and we’ll help identify the appropriate replacement.
