Electronic floor temperature controller with clock and remote sensor (for floor heating/wall and ceiling heating) HTRRBu Surface-mounted installation – Berlin 3000
Technical data
Application
Design:
Berlin 3000
Time-dependent temperature control (for example, of electrical heating systems) for floor, fringe zone, bath- room, ceiling, tiled stove, marble and wall heating systems or tempering systems. It can be used as a master (pilot reg- ulator) for the temperature reduction of other controllers. Controllers of the series FETR, RTBSU and RTBSB are suitable for use as slaves (satellite controllers). Note: The sensor line must be routed in a protective duct. Parallel routing together with lines that carry AC voltage is not permissible. Programming procedures for every day, familiar from mechanical timers, by means of “electronic tabs”. Short- est switching time 15 min. General features: Pilot function; ECO function; ECO value adjustable; display “ECO”; display “On/Off”; display “Heating”; child-safe features; power reserve (approx. 4–7 days); learning function; valve protection; holiday setting; party setting; automatic ad- justment to standard/daylight savings time; mechanical range limitation; reduction/comfort/automatic button; external setting; operation using direct-dial buttons; on/off button; information button; party function button; holiday setting button
