 Product Description

Individual room control for demand-based regulation of the room temperature, lighting and sunshading to create a comfortable room climate with minimum energy consumption.

The ecos311 single-room controller enables energy-optimised room control and thus ensures minimum energy consumption.

The single-room controller can be programmed with CASE Suite to fulfil the requirements of a wide range of applications in room automation as a BACnet MS/TP controller – application-specific controller (B-ASC). For example, the controller can be used for the control of fan coil units, chilled/heated ceilings, radiator heaters, underfloor heating and VAV systems. When combined with an ecoUnit room operating unit and additional ecoLink I/O modules, it can also perform further functions in the room such as control of window blinds and lighting.


- Part of the SAUTER EY-modulo 3 system family (BACnet MS/TP)
- BACnet MS/TP communication (EN ISO 16484-5)
- BACnet room controller (B-ASC) for fan coil unit, chilled beam, chilled ceiling, radiator heater, light,control of window blinds, variable volume flow control (VAV) etc.
- Individual adjustment of the setpoints via ecoUnit 3 room operating units (EY-RU 3**)
- Optimisation of energy consumption using presence function, monitoring of window contacts, demand-controlled switching of fan speeds and time-dependent setpoint specification
- Freely configurable time programme (BACnet Schedule objects)
- Freely programmable with CASE Suite software (based on IEC 61131-3)
- Expandable with ecoLink I/O modules for lighting and control of window blinds
