Double check the batteries to make sure they are installed correctly. If one of the batteries in the outdoor sending unit is in backwards, it will not send the outdoor data. On the indoor unit, there is typically one battery that is used for receiving the signal from the outdoor unit. If all of the batteries are in correctly but that one, you will see the display and the indoor temperature information, but the outdoor information will not be displayed. If there are reset buttons, also try them.

My outside (transmission) unit is reading 20-30 degrees above the correct temp and sending the high readings to the inside (receiving) unit.


Replace the valve body. Newer units, you can replace the internal wiring harness. It comes with the temp sensor.

Model 00754W4 does not sense outside temperature..new batteries have been placed correctly in both inside and outside units..noW what do I do?


We would recommend a reset of your unit. Please verify that you are using good-quality, standard alkaline batteries such as Energizer or Rayovac, then follow the steps below.
1. Bring both the sensor and display unit indoors and remove at least one battery from each.
2. Make sure the A-B-C switch on both units match. Sometimes changing to a different channel can help.
3. Reinstall the battery in the outdoor sensor.

4. Reinstall the battery in the display unit.
5. Let the units sit within a couple feet of each other for about 20 minutes to gain a strong connection.

Hello Peter. I have just purchased a tx6470 and have had exactly the same problems.
Just subsitute the up/down buttons for hr/rcc.
The 1 2 3 positions are the channels that the outside unit transmits on,you can check this by looking at the inside display where it shows ch in the outside display.
Regarding the city code just make a guess to a large city near you, the British cities are lumped together London is Lon Glasgow is Gla Edinburgh is Edh.
The day Do. I did a reset of the date and it cleared to the correct day
To get the outside details to reappear, remove and refit battries from inside unit and reset everything.

I had the same problem, Since the outside temp wouldn't read, I figured it was the outside unit batteries. Went through half a dozen AAA batteries and wouldn't read. It was the indoor unit. Had the same bats I installed 3 years ago. DUH! Replaced the AAA, and all was well. When the inside batteries die out, it has just enough juice to read indoor temp, but not enought to sense exterior signal.

I have this model and the outdoor temp sensor isnt working, and yes both modules have brand new batteries in them. what should i do to get the outdoor temp sensor to work.


My outside display stopped working, but the inside display still worked. I found that one of the two batteries in the inside unit was almost all the way dead. Once I replaced both batteries the outside display worked. I also checked the batteries in the outside unit. After all batteries were installed, I pushed the small button that is inside the battery compartment on the outdoor unit. It's now working perfect..

Outside temp not measuring correctly


I keep the outside unit of our in/out set under a coffee can shaded under a bench; one could argue the aesthetics but shielding it from wind and sun is mandatory otherwise one can get record temps pretty often.
The outside units generally transmit to the receivers only every few minutes to keep battery consumption down so moving them won't necessary gie you an immediate change.
