What an awesome thread! I'm gonna look into the Economizer control. Another control I installed was a programmable thermostat for the tank to reduce the standby firing of the boiler. I was getting annoyed hearing my CGi cold starting boiler firing up all day in summer even after I installed heat trap loops and nipples. If you set the on-off far enough apart you can keep the boiler from firing all day between morning showers and dinner cleanup.
