Why connect EIB to Comfort?
The EIB is a distributed system consisting of sensors (switches, light sensors, motion sensors) and actuators (for lighting, dimming, fan, curtain/blinds), with each device having its own intelligence and with a specific function. Comfort is a home controller which coordinates the activity of home appliances and equipment, acting as the “brains” for the home. For example, when an intruder alarm is activated, the lights in the immediate area can come on automatically, and when someone comes in the front door when the security system is armed, the hall lights can be switched on, or when the system is armed to Night mode, the lights can be dimmed for a few minutes and then switched off. This requires the intruder alarm system and the lighting system to work closely together. Comfort can switch lights through main-rated relays but it does not dim lighting directly, it works with lighting systems (X10, EIB, C-Bus, ,Lutron etc.) . Comfort complements the EIB system by providing a comprehensive telecontrol function with up to 300 functions, and the ability to send infrared signals to home entertainment and airconditioners. Through the Comfort Web Server Module, the EIB system can be controlled from a local Area Network, or the Internet.

UCM/EIB
The UCM/EIB connects Comfort to the EIB. The EIB bus is connected to a two-pin terminal block on the UCM/EIB. No additional equipment is required on the EIB side. This provides a two-way interface between Comfort and the EIB, i.e., Comfort is able to send as well as receive telegrams on the EIB. Signals on Comfort are isolated from the EIB by optical isolators.
