TEC3000 Series Networked and Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers with Dehumidification Capability Installation Guide 1 Refer to the QuickLIT website for the most up-to-date version of this document. Applications The networked TEC3000 Series Thermostat Controllers are stand-alone and field-selectable BACnet® MS/TP or N2 networked devices. Wireless networked models of the TEC3000 Series Thermostat Controller are also available. Proportional Fan Coil and Individual Zone Thermostat Controllers provide control of the following: •Local hydronic reheat valves •Pressure-dependent variable air volume (VAV) equipment with or without local reheat •Two- or four-pipe fan coils •Cabinet unit heaters •Other individual zone equipment using an on/off or floating control input The networked models feature a field-selectable Building Automation System (BAS) BACnet MS/TP or N2 communication capability that enables remote monitoring and programming for efficient space temperature control. The wireless models are compatible with the WNC1800/ZFR182x Pro Series Wireless Field Bus System that enables communication with a building automation system (BAS). All models include a USB port configuration that reduces installation time by allowing simple backup and restore features from a USB drive, which enables rapid cloning of configuration between like units. Some models have occupancy sensing capability built into the device. These thermostat controllers maximize up to 30% energy savings in high-energy usage commercial buildings, such as schools and hotels, during occupied times by using additional standby setpoints. All models feature an intuitive onboard touchscreen UI with backlit display that makes setup and operation quick and easy. For Single-or Two-Stage Economizer Thermostat Controller models, only the single-speed fan configuration is supported. For TEC3x1x and TEC3x2x models, multiple fan configurations are supported for fan coil equipment types, as follows: •Single-speed •Multi-speed (two or three discrete speeds) •Variable-speed/EC motors (0 to 10 VDC control) Some models support dehumidification on two-pipe fan coil units with reheat, and four-pipe fan coil units with or without reheat. When no heating is required, the thermostat controller monitors space humidity and activates dehumidification control as necessary. Heat and/or reheat is used as required to maintain the space temperature. For optimal dehumidification performance, use a fan coil unit that has a multi-speed or variable-speed fan (VSF).

IMPORTANT : Le TEC3000 Series Thermostat Controller est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du thermostat controller risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du thermostat controller. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: •Reorient or relocate the receiving antenna. •Increase the separation between the equipment and receiver. •Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. •Consult the dealer or an experienced radio/TV technician for help. This Class (B) digital apparatus meets all the requirements of the Canadian Interference-Causing Equipment Regulations. Cet appareil numérique de la Classe (B) respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.TEC3000 Series Networked and Wireless Proportional Fan Coil and Individual Zone Thermostat Controllers with Dehumidification Capability InstallationGuide 3 •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 being monitored 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).
