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.
