How do I get the -- away and get the outdoor temperature to work?

The "OP sensor not connected" error message on a Honeywell HZ432 zoned 3-way AC unit indicates that there is a problem with the outdoor temperature sensor. The outdoor temperature sensor, also known as the outdoor sensor or the thermistor, is responsible for measuring the outdoor temperature and sending the data to the thermostat. If the sensor is not properly connected or is malfunctioning, the AC unit may not cool properly or may not function at all.
Here are a few steps you can take to troubleshoot and fix the problem:

1. Check the sensor connection: Make sure that the outdoor temperature sensor is securely connected to the thermostat. If the connection is loose, the sensor may not be able to send the correct data to the thermostat.
2. Check the sensor location: Make sure that the outdoor temperature sensor is located in a suitable place where it can accurately measure the outdoor temperature. It should be in a shaded area, away from direct sunlight and heat sources.
3. Check the sensor wiring: Make sure that the sensor wiring is not damaged or frayed. If the wiring is damaged, it will need to be replaced.
4. Replace the sensor: If the sensor is malfunctioning, it will need to be replaced.
5. Check the thermostat: Make sure that the thermostat is set to the correct mode and temperature.

sounds to me like your thermocouple is loose just go to where it connects to the gas valve and tighten it most times this happens after it has been replaced, because temperature changes loosen them also make sure the pilot flame is directly on the thermocouple , sometimes dust gets in to the pilot and changes direction of the flame making it "grade the thermocouple, with the main burner on the air flow sometimes "moves the flame and the thermocouple thinks it went out and shuts down the main burner. extinguish the pilot, either blow it out with canned air, or use a q tip to reach down and dust it out then re light. should be good

Check the battery in the outdoor unit, resync them per the instructions, if that does not work check for interference.

Make sure the indoor filters are clean. The outside unit will continue to run until the indoor reaches the temperature you have selected. Dirty filters can throw the temperature out. Its common for outdoor units to freeze up when on heating mode if the ambient air temperature is below 5 degrees Celcius.. The machine should however, defrost itself. There could be a problem with one of the pipe or air sensors on the outdoor unit.

Hi Susuan,
One of these methods below should get your device working properly. Good luck!

From the manual:
915MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE SENSOR
The atomic clock will receive the temperature data within 3 minutes. If the temperature data is not being received 3 minutes after setting up (the display shows "- - -"), then please check the following points:
1. The distance of the atomic clock or outdoor temperature sensor should be at least 6 feet (2meters) away from any interfering sources such as computer monitors or TV sets.
2. Avoid placing the receiver onto or in the immediate proximity of metal window frames.
3. Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception.
4. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference.
Note:
When the 915 MHz signal is received correctly, do not re-open the battery cover of either the outdoor temperature sensor or atomic clock, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur.
The maximum transmission range is 330 feet (100 meters) from the outdoor temperature sensor to the atomic clock (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).

I have the Blackberry Tour.......I work in all kinds of environments....so I get dust, dirt, and debris in my trackball......every 3-4 weeks I cannot move the trackball.......all you gotta do is get AIR DUSTER, the same you use for your computer keyboard etc. and keep it about 3-4 inches away and spray the air at your trackball and move it around......just keep spraying it for about 1-2 seconds at a time and move the ball around after every spray and you are good to go!!!!!

Your computer is getting too hot. Get canned air and spray all the dust out, especially the dust in and around the proccessor and heatsink (big metal grille).
Then move the computer off shaggy carpet and move it several inches away from the wall.

If that doesn't wokr you may have hardware incompatabilites, like with your memory or graphics card.

Sometimes too much dust around the heating elements can cause the heater to switch off to prevent a fire. Check for dust build up first. You can try using a can of compressed air that can be found at many electronic stores.
