HEATING TECHNOLOGY

ROOM TEMPERATURE CONTROLLER, MECHANICAL, RTBSB SURFACE-MOUNTED ‘ULTRA-THIN’ INSTALLATION – DESIGN BERLIN 1000

TECHNICAL DATA

APPLICATION

Design:

Berlin 1000

Control or monitoring of temperatures in closed spaces.

Surface finish: Housing colour: Housing material:

glossy

pure white, similar to RAL 9010

Valve actuator: normally closed. If nor - mally open heating valves are available, they should be connected 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.
