Check the disconnect switch and make sure that both the fuses are good and not shot. If one is shot then the system wont work. There are two fuse. Also be careful due to you will be working around 210 volts

There is no way to turn off beeping. From this site: http://www.chaneyinstruments.com/FAQ.aspx
found solution - search for - Q: My wireless weather station periodically beeps, why?
A: .. unit's ability to detect a foreign radio frequency of another wireless unit when that unit transmits a signal. .. any wireless devices transmitting on a radio frequency have the potential to interfere with each other. Limit the amount of wireless devices to lesson the chance of interference. When beeping occurs, one device will need to be deactivated.
There is no way to turn off beeping, d/s designers forgot. I had the same problem, another external temp gauge showed up on the other channel, so my neighbor or someone is using the similar unit. MY SOLUTION: opened back of case and cut black wire to piezo speaker (at base if rear cover opposite side of stand-up prop) that creates beep. Don't use any sound features, ALL good now.
SOURCE: indoor unit flashes 5 times. error code meaning?
I have a lg aircon model lsr122v-4 and when I turn it on it stays on for about 2 mins then turns off. Once it's off it flashes a green light 5 times and continues in intervals. What could possible be wrong with it?
