TEC3000 Series Networked and Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers with
Dehumidification Capability Quick Start Guide

For wireless models, also locate the thermostat controller:
• 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
• 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 passive infrared (PIR) models, be sure that the thermostat controller 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 required 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 found in typical building
interiors.
Notes:
• Allow for sufficient clearance to insert a USB drive into the USB port
• 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).
