  1. TR20 Series WirelessTraining Slides New Product Introduction March 2009

  2. Benefits to Distributors and Contractors • Retrofit job where re-running wire is difficult or impossible? • The latest in technology is requested by the building owner? • Code requires running expensive conduit for all wiring? • Tall ceilings? No good place to run wires? • Have a building where walls will be moving? • Want to substantially reduce labor cost on any new or retrofit install? For all these reasons and more, consider wireless!

  3. TR20 Series Wireless Overview • Point to Point • Direct replacement for a wired sensor • Can be used with Spyder, XL10, T7350/51 thermostats, etc • Not compatible with TB7220 or TB8220 thermostats, or XL15 • Two Sensor options • With temperature only • TR21-WK kit or TR21-WS sensor only • With temperature, setpoint knob, and override button • TR23-WK kit or TR23-WS sensor only • Sold as a kit - matched pair. • On board signal strength indicator • No need for diagnostic tool. Receiver Wireless sensor Replace a wired sensor, without the wires!

  4. TR20 Series Wireless Specifications Basic Specs • Protocol – 2.4 GHz, 802.15.4 compliant, FCC approved. • Open Range – 3000 feet • Typical Range in a Building – 100 feet • Accuracy – +/- 1ºF (+/-0.5ºC) from 54-86ºF (12-30ºC) • Battery life approximately 5 years with alkaline batteries (included), 7.5 years with lithium batteries • (this can vary depending on how often the override button is pressed). Receiver Wireless sensor

  5. TR20 Series Wireless Sensors Sensor Types • Sensors are available in either the TR21 style (temperature only) or TR23 style (temp, override button, and setpoint knob). • Sensor transmission rate is every 30 seconds • If override button is pressed, transmits immediately. • To save battery life, override light will not remain on after button is pressed – but system overrides none-the-less.

  6. TR20 Series Wireless Installation Installation steps for the wireless kit TR2X-WK • Mount the receiver next to the controller • Wire the receiver to the controller just as you would a wired sensor. Power the controller. See other slides for wiring • Insert batteries into the sensor Communication should start automatically after 5-10 seconds. • Press the signal strength indicator on the side of the sensor. Signal strength LED flashes, see table below. • Green is strongest, yellow is weaker but acceptable. Whenever possible, mount in locations giving a green signal.

  7. TR20 Series Wireless Dips Prebound Kits and Dip Switches • TR21-WK and TR23-WK kits come shipped with sensor and receiver pre-bound at the factory • No need to bind kits in the field or touch dip switches! Just power both devices, communication starts automatically. • Pre-bound kits have binding dip switches all set at the OFF position – each pre-bound kit communicates on it’s own unique “channel”. • In case of replacement, dip switches are provided to bind any sensor to any receiver! Make sure to set dips differently at each kit in a given building. • Labels on the receiver can be used to record dip positions.

  8. TR20 Series Wireless Dip Switch settings • S1 is for controller selection. Default setting (1 on, others off) works for XL10, Spyder. See installation instruction for other options. • S2 and S3 dips on receiver must match sensor dips, see diagram. Pre-bound kits come with all dips in OFF position, no need to adjust.

  9. TR20 Series Wireless Compatibility • Can replace any standard TR21, TR22, TR23, TR24, or T7770A, T7770B, T7770C, T7770D wall module. • Use on Spyder or XL10 controllers. Not compatible with all Honeywell controllers. Wiring diagram Wiring to an XL10

  10. TR20 Series Wireless Compatibility (con.) Wiring to a Spyder controller (low bat wiring is optional)

  11. TR20 Series Wireless Compatibility (con.) Wiring to T7350 and T7351 thermostats (not compatible with TB7200 or TB8220 thermostats) T7350/51

  12. TR20 Series Wireless Low Battery Signal • With approximately 2 months of battery life remaining, the override button LED will flash red every 15 seconds. • The low bat Digital Output on the receiver will close • Use this as a digital input on your controller to signal a low battery alarm. • Note: Low battery indicator does not occur when no batteries are installed, or if batteries are completely dead. • Replace batteries every 5 years, or when low battery signal occurs.

  13. TR20 Series Wireless General Installation tips • Do not mount receiver or sensor in metal enclosures • If mounted on metal, try to keep line of sight between sensor and receiver as free of metal as possible (ducts, metal book cases, etc.) • Gypsum (drywall) and windows will not significantly affect the signal. Metal studs don’t interfere much unless you have an oblique angle through the wall. • Always check signal strength indicator before installing sensor ideal Oblique angle less preferred wall wall
