Forecast and time zone never update

Model 75077A2 was installed on April 30.  I don't recall seeing a "learning" icon but the forecast symbol has not changed since I got it.  Also, I set the unit for MST but it displays an hour early.  I finally set it to CST so that it reads correctly.  I can't find any help in Communities.   Please advise how to proceed.

Hi dickgb,

If you are located in MST, and you live in a location that recognizes Day Light Savings Time, you would want to be sure the DST feature is turned on. 

The learning mode icon should have appeared when you initially powered the unit on.  This icon shows just above the future forecast.  You may refer to page 3 #1 of the instruction manual to view where the learning mode icon is found:

If the forecasting icon has not changed, you may want to reset the unit following the steps below.  This will restart the learning mode as well.

Before proceeding with the reset, please check your batteries. We recommend that the batteries meet the following criteria:

• Verify you are using standard alkaline batteries such as Rayovac or Energizer. Lithium batteries can be used in the outdoor sensor if you are in a location that will frequently see temperatures below -4oF/-20oC. (Rechargeable batteries, as well as batteries that indicate a heavy-duty quality are not recommended, and may cause irregularities.)
• Verify that you are using a fresh set of batteries. The battery expiration date should be at least 6 years out. Batteries can lose 3% of their power or more every year in storage.

1. Bring both the sensor and display unit indoors and position them side by side.

2. Remove all batteries from both the sensor and the display unit. (If the display has an AC adapter, please unplug this, as well, to completely power down the unit.)

3. Locate the A-B-C ID switch inside each battery compartment. Make sure that the two parts are set to the same position. Please change both parts to the next available letter on the ID switch, as this can help to reset the unit.

4. Reinstall batteries in outdoor sensor first. (Please be sure that the red light on the front of the sensor blinks, as this will assure that the sensor is powered on.)

5. Reinstall batteries (and/or reconnect AC adapter) to the display last.

6. Let both sensor and display sit side by side to establish connection. (Leaving the devices side by side for 30 minutes will allow you to verify accuracy by comparing the indoor and outdoor readings shown on the display. For accuracy standards, please visit
7. After a connection has been established, the sensor can be placed outdoors.

Please let us know if we can be of any further assistance to you!
