EECOM is a station in both the Habitat and Mission Control. The purpose of EECOM is to monitor the environmental data for the habitat, and to perform such operations as venting or pressurizing modules, scrubbing carbon dioxide, or adding oxygen. The Mission Control EECOM station is the only one capable of opening doors.
Historically, EECOM stood for Electrical, Environmental, and Communications systems, though the communications part of the job was moved to a station called INCO during the Apollo program. EECOM monitored electrical systems including the fuel cells and cabin pressure control systems from the Mission Control.
Spacesim has a station called EECOM both aboard the Habitat and in Mission Control who is in charge of monitoring changes in cabin pressure, and regulating the atmosphere on board the Habitat to conform to nominal parameters. A separate station for monitoring all electrical systems called Engineering was developed in 2006-07, and allows control over the Habitat Reactors and the Power Grid.
The EECOM station also contains the warning lights for imminent space-junk collision, known as the "asteroid watch."
In Mission Control, the system also contains radiation monitors, to allow medical personal in Mission Control to monitor the safety of the crew in response to harmful levels of radiation.
In 2010-11 EECOM had all raditation duties coded in by Jim Magwood in response to problems involving radiation during mission Drake-Sagan 2011. This addition to EECOM includes the integration of the previously separate RAD program, which was updated during the integration, as well as a backup routine for the radiation values.
James Cooper was the Habitat EECOM for the 2006-07 Mission to Borrelly. Unfortunately, the crew of that mission had several close encounters with abnormal pressures due to Mr. Cooper being colour-blind, and therefore unable to distinguish between the green "safe" and yellow "warning" labels the software placed on the monitor. Prior to the mission, Mr. Cooper had not realized that there was more than one non-red color. Software rewrites were planned after this to avoid further disaster, but the need was gone after Mr. Cooper graduated from Lisgar.
