TR21-WS, TR23-WS, TR21-WK,


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


— T7350, T7351, and TB8575 low-voltage SuitePRO™


— 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


• 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

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


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.
