TX4U Outdoor Temperature/Humidity Sensor

The TX4U outdoor temperature/humidity sensor can be added to your existing units in operation. The outdoor temperature/humidity sensor measures the outdoor temperature and humidity (or any other location you wish to know the temperature and humidity) and transmits the

data to the indoor display station.

2.Mounting bracket.

3.Rain protector

4.Two each, ½” Philips mounting screws.

5.One strip double sided adhesive tape.

6.Instruction manual and warranty return card.

ADDITIONAL EQUIPMENT (not included)

1.One Philips screwdriver.

2.One Flat screwdriver.

3.Two fresh AA 1.5V batteries.

I. SETTING UP

Before you begin, assign a number to each outdoor temperature/humidity sensor (i.e. #1 for outdoors, #2 for the basement, etc.) if you have multiple sensors. This will help you determine which temperature, from which outdoor temperature/humidity sensor, you are reading on the indoor display station.

Note: Remove batteries from all existing units in operation—including outdoor temperature/humidity sensor units and indoor display stations. When setting up multiple units it is important to insert batteries first into all the outdoor temperature/humidity sensors, and in numeric sequence. Second install batteries into the indoor display station. Transmission problems will arise if this is

not done correctly and if the total time for setup exceeds

6minutes.

A. BATTERY INSTALLATION

Follow these directions when first setting up, when replacing batteries, or for resetting purposes.

1.Remove the batteries from all existing units in operation.

2.Remove the battery covers to all outdoor temperature/humidity sensors. Simply slide the battery cover down to remove.

3.Place outdoor temperature/humidity sensors in sequential order.

compartment

Note: Outdoor temperature/humidity sensors will not usually read the same temperature. This is due to variants such as drafts and handling. This is normal.

1.Observe the correct polarity and install 2 AA alkaline batteries in each unit in sequential order. The batteries will fit tightly—make sure they do not spring free. This may cause start-up problems.

2.Replace the battery cover, rain protector, and mounting brackets.

3.Observing the correct polarity, install batteries into the indoor display station (refer to the indoor display station’s manual). Replace battery cover.

4.Wait 5-6 minutes or until both indoor and outdoor temperature and humidity are shown on the LCD of the indoor display station.

5.Refer to indoor display station’s instruction manual for more specific details.

II.MOUNTING

Note: The sending range of the outdoor temperature/humidity sensor is 80 ft. However, obstacles such as walls, concrete, and large metal objects can reduce the range. Before permanently mounting, place units in their desired location to see if a reading is obtained. There should be a change of temperature in the OUTDOOR LCD within 6 minutes. If the indoor display station loses the signal from the outdoor temperature/humidity sensor, it will display the last temperature reading for 15 minutes. After 15 minutes of not receiving any signals the OUTDOOR LCD of the indoor display station will display “- -. –”.

The outdoor temperature/humidity sensor can be mounted in two ways:

•with the use of screws or,

•using the adhesive tape.

A. MOUNTING WITH THE SCREWS

1.Remove the mounting bracket from the outdoor temperature/humidity sensor.

2.Place mounting bracket over desired location. Through the 3 screw holes of the bracket, mark the mounting surface with a pencil.

3.Where marked, drill holes into mounting surface using an appropriate size drill bit.

4.Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the bracket.

5.Snap the outdoor temperature/humidity sensor into place on the mounting bracket.

B.MOUNTING WITH ADHESIVE TAPE

1.With a nonabrasive solution, clean and dry the back of the mounting bracket and the mounting surface to ensure a secure hold. The mounting surface should be smooth and flat.

2.Remove the protective strip from one side of the tape. Press firmly into the designated area on the back of the mounting bracket.

3.Remove the protective strip from the other side of the tape, and position the outdoor temperature/humidity sensor in the desired location.

III.MAINTENANCE AND CARE

1.Extreme temperatures, vibrations, and shock should be avoided to prevent damage to the units

2.Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents, they may mark the displays and casings

3.Do not submerge in water.

4.Do not subject the units to unnecessary heat or cold by placing them in the oven or freezer.

5.Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for repairs.
