HEATING TECHNOLOGY
ROOM TEMPERATURE CONTROLLER, MECHANICAL, RTBSB SURFACE-MOUNTED INSTALLATION – DESIGN BERLIN 2000
TECHNICAL DATA
APPLICATION
Design:
Berlin 2000
Control or monitoring of temperatures in closed spaces. Suitable for all heating systems. Valve actuator: normally closed. If normally open heating valves are available, they should be connected
Surface finish: Housing colour: Housing material:
matt
pure white, similar to RAL 9010
ABS plastic
Storage temperature: Permissible atmospheric humidity: Electrical connection:
−20 to +70 °C
Max. 95% rel. humidity, non-condensing screw-type terminals 0.12 mm² – 2.5 mm² surface- / wall-mounting (4-hole assembly on flush-mounted socket)
with the cooling output of the changeover switch (toggler).
Up to a maximum of 10 actuators for valves can be connected (normally closed, NC); with a toggler, on the NO contact, up to 5 units (in this context, please check the switching capacity listed in the TECHNICAL DATA). Installation note: Owing to the existing wiring space in the controller itself, installation on a flush-mounted socket is recommended, but it can also be performed on a plane, non-conducting substrate. Explanations of technical terms can be found in the annex to the product catalogue or at www.alre.de.
