SOURCE: 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.

SOURCE: outside remote sensor, when i insert batteries,get


The problem can be from two point of view.

1). from the battery capacity if not up to the voltage expected to be use.

2). And also if the battery sensor is not compatable with it.

However, what you need to do is to test run the system with another battery in other to be able to locate were the problem is from if from the battery or the the system it self.

you can also get back to me after the test.

Why is indoor display not showing outside temperatures?

If the condition comes and goes, the outside unit may be exposed to extreme temperatures or the batteries may be too weak. If the condition occurred after battery replacement, remove all batteries then reinstall the outside battery and wait for it to "initialize" and begin sending data. ReInstall the inside battery and you should see the outside temperature displayed.

Atwood 10 gallon H2O heater- replaced thermal couple and electrode spark and sensor but heater comes on with switch, heats water for 10 to 15 mins then burner goes out. Can hear a couple of switching...

I'd check that ECO and thermostat discs are making contact properly with tank.Just peel back foam cover on outside of tank that has ECO and THERM marked on it. If they are installed correctly, replace them.
