TX7U Outdoor Temperature/Humidity Sensor

The TX7U 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.

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.

Remove batteries from all existing units in operation—including outdoor

Note:

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 6 minutes.

A. BATTERY INSTALLATION

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

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

2. Using a screwdriver, unscrew and open the battery cover located
at the front of the outdoor temperature/humidity sensor.

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.

3. 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.

4. Replace the battery cover, screw and mounting bracket.

5. Observing the correct polarity, install batteries into the indoor

display station (refer to the indoor display station’s manual).
Replace battery cover.

6. Wait 15 minutes or until both indoor and outdoor temperature and

humidity are shown on the LCD of the indoor display station.

7. Refer to indoor display station’s instruction manual for more

II. MOUNTING

specific details.

Obstacles such as walls, concrete, and large metal objects can

Note:

reduce the effective range of the temperature/humidity sensor. 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 three
ways:

A. MOUNTING WITH THE SCREWS

• with the use of screws

• using the adhesive tape

• using the mounting bracket as a stand

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.
