Location Considerations
Locate the TEC3000 Series Wireless Thermostat Controller:
• on a partitioning wall, approximately 5 ft (1.5 m) above the floor in a location of average temperature, allowing
for vertical air circulation to the TEC
• away from direct sunlight, radiant heat, outside walls, outside doors, air discharge grills, stairwells, and from
behind doors
• away from steam or water pipes, warm air stacks, unconditioned areas (not heated or cooled), or sources of
electrical interference
• outside of a recessed area, metal enclosure, or shelving unit
• on the same building level as the other wireless devices on the same personal area network (PAN)
• at least 2 in. (51 mm) away from any metal obstruction
• in the direct line of sight to other wireless devices on the same PAN. Signal transmission is best if the path
between the TEC3000 and other wireless devices is direct as possible. Line of sight is desirable but not
required. See Table 1 for recommended and maximum distances.
• away from metal and large solid obstructions (including equipment rooms and elevator shafts and concrete or
brick walls) between the TEC3000 and the ZFR Pro Router/Repeater or ZFR Pro Coordinator Radio
• in a clear path between the integrated passive infrared (PIR) occupancy sensor (if equipped) and the space
being monitored
• within range of two or more wireless devices on the same PAN. Redundancy in the layout provides the best
reliability in wireless installations
• at least 20 ft (6 m) from a microwave oven
The effective transmission range and distance for indoor applications vary because of wireless signal absorption
and reflection due to metal obstructions, walls or floors, and furniture found in typical building interiors.
For integrated passive infrared (PIR) models, ensure that the thermostat controller is located centrally where
occupant movement is frequent, and where the unit is not blocked by a plastic tamper resistant enclosure (such as
the GRD10A-608). The plastic enclosure blocks the occupancy sensing capability.
Note: For more details on using ZFR Pro Series communication devices, refer to the WNC1800/ZFR182x Pro
Series Wireless Field Bus System Technical Bulletin (LIT-12012356).
