For use with Honeywell weather stations.
The TS33F Temperature & Humidity Sensor with Probe works with specific Honeywell weather stations; check your owner's manual for compatibility!
Honeywell weather stations can use up to 3 remote sensors. The TS33F has a transmission distance of 100 feet (line of sight).
Note: The TS33F will function without the included temperature probe; a waterproof plug covers the jack when the probe is not installed.
