Installation Notes

Point the TX61U-IT solar panel toward the best

available light source to recharge the batteries, but

avoid a location in direct sun as it will cause incorrect

temperature readings. We recommend facing the solar

panel East to catch the early morning sun, and placing

under an eave or overhang to avoid overhead sun.

The TX61U-IT sensor uses internal rechargeable

batteries to store the collected solar power.

The sensor features a high-efficiency solar panel that

maintains a full charge with minimal indirect light. Do

not place in direct sun, as this will cause incorrect

temp readings.

Fog and mist will not harm the sensor but direct rain

must be avoided.

The TX61U-IT sensor has a wireless range of 200 feet

(60.96 m). Keep in mind that the 200 ft range equates

to an open air scenario with no obstructions, and that

radio waves DO NOT curve around objects. The actual

transmission range will vary depending on the path of

the signal. Each obstruction (roof, walls, floors,

ceilings, thick trees, etc.) will effectively cut the signal

range in half.

Example: If the TX61U-IT sensor, with a 200 feet

(60.96 m) range, is mounted on an exterior wall, the

signal must then pass through one exterior wall, one

interior wall, and across the 10 feet (3 m) width of the

room between the 2 walls to reach the wireless

display. The first wall will reduce the range to 100 feet

(30.48 m), and the second wall will reduce the range to

50 feet (15.24 m). Factoring in the 10 foot room, this

leaves a maximum of 40 feet (12. 2 m) of remaining

signal range.

This allowance is typically enough for a frame wall with

non-metallic siding; however certain materials can

reduce range even further. Metal siding, stucco, and

some types of glass can reduce signal range by as

much as ¾ or more, compared to the ½ reduction

typical of most obstructions. It is possible to receive a

signal through these materials, however maximum

range will be much less due to their tendency to

absorb or reflect a much larger portion of the sensor’s

signal.

The TX61U-IT sensor measures and transmits signal

about every 8 seconds when its battery voltage is

higher than 2.5V.

Once the reset button is pressed on the TX-61U

sensor and the batteries are inserted into the wireless

display, the units will try to synchronize

communication. If the wireless display fails to receive
