Try cleaning the outdoor thermometer transmitter unit by opening it up enough to spray compressed air (Ultra Duster or similar) on the temperature sensor. It fixed the hh.h error for me.
Very likely you have high pressure in your area. HHH means that the pressure is higher than the unit can read. Check local barometer readings to confirm.
HH means it is showing the high temperature you (most likely accidentally) set with the MAX MIN / + button, which is easy to do when setting the clock. Just press that button again until the reading appears.
I'm assuming it just stands for "High Humidity". It wasn't raining at the time, but it sure had been earlier, so perhaps if it's over some number (like 90%), it just says "HH".
If I'm not mistaken, it seems like it means there is a problem with the outdoor temperature sensor. This is strictly from memory though and I could be wrong. If you press the up and down arrow buttons at the same time it should display the outdoor temperature for a few seconds and then the indoor humidity. You might try this to see if it displays an outdoor temperature that is close to being right. If it doesn't there is a good chance the sensor is bad or there is a broken wire somewhere.
