Important Notes
Please read before installing.
1. CAUTION! To avoid overheating and possible damage to other
equipment, do not use to control receptacles, fluorescent lighting
fixtures, motor-operated or transformer-supplied appliances.
2. Install in accordance with all national and local electrical codes.
3. Do not use for loads switched from 2 or more locations.
4. DO NOT use Maestro controls for compact fluorescent lamps.
®
5. When no "grounding means" exist within the wallbox then the NEC
2008, Article 404-9 allows a control without a grounding connection to
be installed as a replacement, as long as a plastic, noncombustible
wallplate is used. For this type of installation, cap or remove the green
ground wire on the control and use an appropriate wallplate such as
Lutron's Claro or Satin Colors series wallplates.
® ®
6. Protect Timer from dust, dirt, and paint when spackling or painting.
7. Do not use where total load current is less than 0.3 A or greater than
5 A (see Timer Capacity Chart for details).
8. Operate between 0 °C (32 °F) and 40 °C (104 °F).
9. Timer may feel warm to the touch during normal operation.
10. Recommended wallbox depth is 2 ½ in (64 mm) minimum.
11. For safety reasons, do not use to control fixtures that are the only
source of illumination for an area.
12. When controlling a combined fan and light load, the total load may not
exceed 3 A.
13. Clean Timer with a soft damp cloth only . Do not use any chemical cleaners.
Multigang Installations
When installing more than one control in the same wallbox, it may be
necessary to remove all inner side sections prior to wiring (see below). Using
pliers, bend side sections up and down until they break off. Repeat for each
side section to be removed. Removal of Timer side sections reduces maximum
load capacity. Refer to chart below for maximum Timer capacity.
