Ganging and Derating:

A typical dimmer is wider than a switch. This increased size helps the dimmer dissipate the internal heat normal to operation.

Dimmers can be ganged together such that the space between them is the same as for switches. To do this, a portion of the fins (heat sink) must be removed. The fins are grooved to make the removal of fins easy with a pair of pliers.

The removal of these fins reduces the capacity (load) the dimmer can control.

Derating Requirements for:

Ariadni®, Diva®, Diva Satin Colors®, Glyder®, Lumea2®, Maestro®, RadioRA®, Rotary®, Skylark®, Spacer®, and Spacer System™ Controls

Derating refers to the reduction of the maximum capacity (load) a unit can reliably handle when fins/side sections are removed.

  1. Accessory dimmers/accessory switches for Spacer System, Spacer, RadioRA and Maestro Smart Remotes do not require derating.
  2. Minimum loads: 40W for Maestro and Spacer dimmers; 60W for Spacer System dimmers; 50W for RadioRA dimmers.
  3. For use with one ceiling paddle fan; prevents fan motor hum.
  4. Total fan plus light load may not exceed 2.5A.
