HEATING TECHNOLOGY

ROOM TEMPERATURE CONTROLLER, MECHANICAL, RTBSU FLUSH-MOUNTED INSTALLATION – DESIGN BERLIN FLUSH-MOUNTED

TECHNICAL DATA

APPLICATION

Design:

Berlin flush-mounted

Control or monitoring of temperatures in closed, dry spaces. Suitable for all heating systems. Valve actuator: normally closed. If normally open heating valves are avail- able, they should be connected to the cooling output of the changeover switch (toggler), e.g.., RTBSU-401.010 Up to a maximum of 10 actuators for valves can be connected (normally closed, NC); up to 5 units on the toggler with a NO contact. In terms of visual aesthetics, the basic controllers (RTBSU-401.xxx#00), in combination with a 55 x 55 mm / 70 x 70 mm cover set, fit perfectly in many switch ranges without the use of an insert frame. The basic controllers (RTBSU-401.xxx#00) in combination with a 50 x 50 mm cover set fit in nearly all switch ranges with the use of an insert frame.
