HEATING TECHNOLOGY

ELECTRONIC FLOOR TEMPERATURE CONTROLLER WITH REMOTE SENSOR (FOR FLOOR HEATING/ WALL AND CEILING HEATING) FETR/RTERU FLUSH-MOUNTED INSTALLATION – DESIGN BERLIN UP

TECHNICAL DATA

APPLICATION

Design:

Berlin UP

Temperature control (e.g., of electrical heating systems) for floor, fringe zone, bathroom, ceiling, tiled stove, marble and wall heating systems or tempering systems, direct floor heating systems. Reduction: With these flush-mounted controllers, the temperature can be reduced by 5 K. For this purpose, potential is applied to the clock input terminal by an external pilot controller or an external timer L1. Note: The sensor line must be routed in a protective duct. Parallel routing to- gether with lines that carry alternating currents is not admissible. The 55x55 mm variants visually fit per - fectly without an insert frame in many switch ranges of 55x55 mm.

Housing material:

PC plastic (FETR) PA6 plastic (RTERU)

230 V AC, 50 Hz −20 to +70 °C

Max. 95% rel. humidity, non-condensing

screw-type terminals (FETR) pluggable screw terminals

Mounting / attachment:

In flush-mounted socket – with suitable cover set, can be adapted to fit virtually any switch range (deep flush-mounted socket recommended)
