Wireless weather stations and digital clocks by Honeywell that display outdoor temperature and, for some models, outdoor humidity require remote sensors to measure these values and transmit them to the main station or clock. While these stations and clocks always include one remote sensor, some stations and clocks can work with up to three sensors. For these products, any desired additional sensors must be purchased separately.
The Honeywell TS33F is white with a red front-panel LED that flashes once when temperature data is being transmitted and twice when the battery gets low. The LCD panel above the LED shows the temperature in your choice of °C or °F and the humidity in percent. The cable and probe are white to match the remote.

The Honeywell TS33F Temperature and Humidity Remote Sensor with Probe is a remote transmitter intended primarily for use with Honeywell weather instruments and clocks that display both temperature and humidity. The TS33F reports the temperature and humidity from its outdoor (or other remote) location to the weather station or clock. In addition to the temperature probe on a 10-foot (3-meter) cable, this sensor has its own LCD temperature and humidity display for local viewing at the location where it is installed.

Because the probe on the TS33F is removable, this remote can sense temperature either by means of the probe or, with the probe removed, by means of its internal sensor. Please be aware that the probe senses temperature only, not humidity. And because the probe and cable are waterproof, the.TS33F can be used for many applications, including pool, pond, or spa temperature, refrigerator or freezer temperature, and greenhouse or soil temperature. Also, in really cold weather, you can use the TS33F to sense outdoor temperature by extending the probe out of a window with the remote safely indoors (in which case the humidity reading will show indoor humidity).

--------------------------------------------------------------------------------

The TS33F is well suited to extended low temperature operation. When temperatures below freezing are expected for an extended time period, you can install lithium AA batteries instead of alkaline. Lithium cells provide superior performance in sub-zero temperature conditions. The display may fade in severe cold, but this is normal for liquid crystals, and the display should reappear when temperatures warm to freezing and above.

In the TS33F's battery compartment are a channel 1, 2, or 3 selection switch, a switch that selects °C or °F for the transmitted and displayed temperature, and a Reset button that you press with a paper clip or similar tool after changing the batteries.

The TS33F Remote Temperature and Humidity Sensor with Probe can rest on a horizontal surface, or it can be wall-mounted via a keyhole slot on the back. The remote transmits 433 MHz signals and operates on two AA alkaline or lithium batteries (not included). Average battery life is approximately 1 year. The LED on the TS33F flashes once when it transmits a temperature reading to the main unit. When it flashes twice, this indicates a low battery condition.

Important Information on Remote Sensor Compatibility: You can use a Honeywell temperature and humidity sensor with a Honeywell product that displays temperature only, in which case humidity is not displayed for the temperature and humidity sensor's channel. Similarly, you can use a Honeywell temperature-only sensor with a Honeywell product that displays both temperature and humidity, but the humidity display for the temperature-only sensor's channel will be blank.

For years, Honeywell has been the name to trust for high-quality indoor environmental controls. Now you can have the same high quality in environmental monitoring. For superior environmental instrumentation, why not go with Honeywell, the name you know you can depend on?
