1. Controlled circuits that do not need to be physically wired together, but always operate in tandem. For

example, perimeter lights, sconce lights, and overhead lights all operating together.

2. Location of controlled lighting zone, relevant to building site/drawings, ﬂoor designation, and room name.

3. Fixture and/or lamp type of controlled lighting zone, including any information describing custom ﬁxtures,

undetermined ﬁxtures, dimmable transformers or ﬂuorescent ballasts, and circuit breaker numbers. This

information can also contain the number assigned to the controlled circuit.

4. Load type of the controlled lighting zone. Load types include incandescent, magnetic low voltage, electronic

low voltage, neon/cold cathode, HID, dimmable/non-dimmable ﬂuorescent ballast, ceiling fans, and switched

3-wire motor circuits. This information is especially important for selecting the correct Crestron module power

rating and type.

5. Dimming requirement for the controlled lighting zone (i.e., whether the lighting level of the loads/ﬁxtures

needs to be ramped up/down or switched on/off).

6. Backup power designation for the controlled lighting zone (i.e., when a load also needs to be assigned to a

separate emergency power feed). These items are assigned to their own separate dimmer, so it can be fed

with backup power.

7. Watts or power rating per ﬁxture regarding the controlled lighting zone. This is used to determine the number

of ﬁxtures that can be powered per each Crestron dimmer module channel, in order not to overload the

dimmer beyond its own power rating. Volts rating for the controlled lighting zone tells the designer the voltage

of the electrical feeds required for that zone, and hence the required rating for the associated Crestron

module. It is recommended, due to electrical codes, to avoid mixing different voltages in a single enclosure.

8. Quantity of ﬁxtures for the controlled lighting zone. This is useful, along with item #6, in calculating the total

power rating (watts) for that particular controlled circuit (item #9).

9. Total wattage or power rating of the controlled lighting zone. This is required in order to determine the total

number of Crestron lighting module channels required for that particular zone, especially if the load of the

total number of ﬁxtures exceeds the rating of a single module channel.

NOTE: National and local electrical codes and the functionality of each user-interface must be taken into

consideration. Always install electrical devices according to the National Electrical Code (NEC), local codes,

and with safety in mind.
