EYR 020: ecolon, DDC individual-room controller

The ecolon EYR020 DDC intelligent unitary controller (with communication capability) is part of the EY3600 family of systems. The EYR020 is a room controller with data communication in accordance with the LONMARK standard. Apart from the ability to interconnect with other LON-certified devices, it can be linked to a building management system. With regard to the input/output configuration, the EYR 020 has been optimised to control fan-coil systems (using object 8020 for fan-coil units). Used in conjunction with the EYB017...EYB02x room operating units, it enables the user to match the indoor conditions to his own particular needs. Window contacts, an occupancy transmitter and other features ensure that energy consumption is kept to a minimum.
