I am having trouble translating these systems. Can anyone explain the difference between these 2 control types? Thank you

Felipe, I don't know—where are you seeing those terms?

We were just wondering about this, too. In the online template under Table IEQc6.1-1, there is a pull-down menu that allows you to select the "Lighting Control Type." The options are Multiple Mode, Dimmer, Multiple Circuit On/Off, Task Lighting On/Off, and Other. We primarily have occupancy sensors throughout our project, so I'm not sure if that falls under Multiple Mode or Other. I couldn't find anything in the definitions, so any guidance would be helpful. Thanks!

Hi Jill, Occupancy Sensors on their own don't count unless they have a manual override. The intent of the credit is to allow users to modify their lighting.

That makes sense. We do have manual overrides, yet I'm still not sure if that counts as a Multiple Mode or Other lighting control type when filling out the template on LEED Online.....

Hi Jill. That's great that you have manual overrides. My sense is that the choice would be the same choice as that which you would choose for a regular on/off switch assuming all occupancy sensors have manual override switches. Hope that helps a bit....I don't have the Letter Template open now so I can't say definitively. It seems that neither Multiple mode or Other would be quite right.

Sounds like multiple mode refers to multiple scene options, e.g. AV, Lectern, Panel Presentation, Whiteboard....

After reading several posts on "multiple mode", it is still confusing. Has anyone uncovered a more definite definition?

I am also wondering… what the definition of "multiple mode"?

I agree with Joyce. Multiple mode control is for multiple lighting effects like in AV rooms, meeting rooms, etc. Multiple circuit ON/OFF is for controlling multiple luminaries using one switch.
