TR21-WS, TR23-WS, TR21-WK,
TR23-WK, WRECVR
The WRECVR receiver and TR21-WS, TR23-WS, TR21-WK,
and TR23-WK are a family of wireless wall modules and
receiver for use with:
— Spyder Unitary Controllers: PUL, PVL, etc.
— Excel 10 W7750, W7751, W7752, and W7753
controllers
— T7350, T7351, and TB8575 low-voltage SuitePRO™
thermostats
— Will not work with TB7220, TB8220 or TB line voltage
thermostats, XL15s, W7762, W7763 or certain other
XL controllers,
— Will work with WEBs-AX™ I/O Module products if
using a separate transformer
— Compatibility with various other non-Honeywell con-
trollers that accept 10K type2 NTC temperature inputs
FEATURES
• Wall module to Receiver (point to point) wireless kits
can replace any standard wired sensor
• Wireless Kits (wall module and receiver) are pre-bound
at the factory for quick installation
• Signal Strength LED built into the wall module
• Low battery indication
• Optional dip switches available to bind any wall
module to any receiver
• Approximate 5 year battery life with AA Alkaline
(included), 7.5 year with Lithium
• Locking screw discourages tampering and battery
theft.

General Rules for Installing Wireless
Wall Modules
Communication between the wall module and receiver can be
influenced by a number of factors. Type and thickness of
building materials and the way in which they are oriented in
relation to the wall module and receiver will affect
communication.
Do not place either the wall module or receiver inside metal
cabinets or enclosures.Try to orient the wall module and
receiver so that if they are separated by a wall(s), the direction
of signal travel is as perpendicular to the wall(s) as possible.
This reduces the effective wall thickness.
When mounting the receiver on a metal duct, stronger
communication is possible if the wall module is on the same
side of the duct so the signal doesn’t need to travel through
the metal duct.
Reduce as much as possible the amount of metal (ducts, file
cabinets, etc.) between the sensor and the wall module.
Standard drywall (gypsum board) does not greatly affect
signal strength.
