EY-RC 301, 302: Room controller, ecos301, 302
How energy efficiency is improvedThe ecos 3 controller enables precise room climate regulation and thus ensures minimum energyconsumption in the room.
Features• Part of the SAUTER EY-modulo 3 system family (BACnet MS/TP)• Single-room controller for an energy-optimised room climate• BACnet room controller (B-ASC) for fan coil unit, chilled beam, chilled ceiling, radiator heater etc.• Individual adjustment of the room climate with the ecoUnit382 room operating unit (EY-RU 382)• Universal PI and/or binary controller sequence for all the analogue and digital input/output signals• Optimises energy consumption thanks to occupancy function, window contact monitoring, demand-
controlled switching of fan speeds and time-dependent setpoint specification• Additional functions: automatic heating/cooling changeover, automatic switching on, setpoint com-
pensation, free external cooling and other• Mathematical functions for universal inputs: subtraction, mean, min. and max.• Eight freely assignable alarm conditions with a selectable status for the outputs for an alarm condi-
tion• Time and weekly calendar function (time software)• Integration into building management system via BACnet router (MS/TP to IP)• Parametrisation with ecoUnit382 room operating unit• System bus: RS485 (BACnet MS/TP)• Bus for operating unit: RS485 (VCPP)
