For networked models, locate the TEC3000 Series Thermostat:
- On a partitioning wall, approximately 5 ft (1.5 m) above the floor in a location of average temperature, to allow 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
- In a clear path between the integrated passive infrared (PIR) occupancy sensor, if equipped, and the space it monitors
For wireless models, also locate the thermostat:
- 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 and Table 2 for the recommended and maximum distances.
- Away from metal and large solid obstructions, that includes equipment rooms and elevator shafts and concrete or brick walls, between the TEC3000 and the ZFR182x or ZFR183x Router/Repeater or ZFR Pro Coordinator Radio
- 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
For integrated PIR models, make sure that the thermostat is located centrally, where occupant movement is frequent. Ensure that the unit is not blocked by a plastic tamper resistant enclosure, such as the GRD10A-608. The plastic enclosure blocks the occupancy sensing capability.
The use of insulating foam pads is necessary for installations where wiring passes through the wall to the thermostat.
For wireless models, 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 that is found in building interiors.
