Technical data

Application

Design:

Berlin 3000

For time-dependent control of temperatures in closed spaces. Suitable for all heating systems.

Surface finish: Housing colour: Housing material: Operating voltage:

matt

pure white, like RAL 9010

ABS plastic

Valve actuator: normally closed.

230 VAC, 50 Hz

It can be used as a master (pilot regulator) for the temperature reduction of other con- trollers. Controllers of series FETR, RTBSU and RTBSB are suitable as slaves (satellite controllers). Programming procedures for every day, familiar from mechanical timers, by means of “electronic tabs”. Shortest switching time 15 min. Load setting: The control accuracy is influenced by the different levels of intrinsic heating of the controller depending on the magnitude of the heating load. By inputting the heating load, this influence is compensat- ed and the control accuracy is retained. General features: Pilot function; ECO function, ECO value adjustable; “ECO” display; “on/off” display; “heating” display; digital actual value display; child-safe features; power reserve (approx. 4–7 days); load setting; actual value cor- rection/measured value correction; learning function; valve protection; holiday setting; party setting; automatic adjustment to stan- dard/daylight savings time; mechanical range limitation; scale: Degrees Celsius; reduction/ comfort/automatic button; external setting; operation using direct-dial buttons; on/off but- ton; information button; party function button; holiday setting button
