The flashing or flickering flame indicates that the thermostat is calling for heat. Only on two stage thermostats, if you have a number 2 or two flames then the system is looking to turn on a second stage of heating to help the first stage. This would be due to the fact that the system is calling for more than three degrees or the first stage hasn't been able to raise the temperature by itself.
The flashing snowflake indicates that the thermostat is calling for cooling. Only on two stage thermostats, if you have a number 2 or two snowflakes then the system is looking to turn on a second stage of cooling to help the first stage. This would be due to the fact that the system is calling for more than three degrees or the first stage hasn't been able to lower the temperature by itself.
Prior to version 5.1 all reminders were set to 3 months (regardless of equipment). It is necessary to enter the system settings menu, set the 1st stage heat equipment to HP and then adjust the service reminder to OFF to disable the reminder. After changing that you can set the system back to whatever option is necessary for your application.
There is nothing in the thermostat to cause a beep. Perhaps a smoke or CO alarm placed nearby is beeping?

EER stands for Energy Efficient Recovery if your thermostat can control up to 2 stages of heating and cooling. In the program mode, EER looks ahead up to two hours before the end of the current set-back or setup temperature period and decides if it is necessary to activate the first stage of heating or cooling to meet the next temperature set point. EER is designed to activate only the most economical stage of heating or cooling up to 30 minutes before the next temperature change when it decides if an auxillary stage is needed to help meet that temperature.
