Did you try turning main breaker off to air hander and then back on?Often a power glich or surge will throw the error code and a simple off /on at breaker will reset.

If this does not correct issue, Check to make sure we have 24 volts from air handler to tstat.If so and still get message EEE thermostat will need to be replaced.
