Radio Range Planning
The ERDRC controller is intended to be used with switches, sensors and
actuators enabled with EnOcean PTM or STM transmitters. Locating the wireless
transmitters to work with the installed ERDRC controller requires planning.
Careful consideration should be made for locating the controllers based on
the construction materials in the space and possibility of tenant’s furniture
disrupting the transmissions. Fire doors, elevator shafts, stairwells, storage
areas and any large metal products create radio shadows and will disrupt
wireless transmissions.
On floor-plan drawings, draw 100 feet (30m) diameter circles to identify optimal
transmitter and controller locations. Refer to the table for range considerations
with other building materials.

Layout Hints
• Avoid transmitting down a length of wall to reduce signal reflection.
