EC011309 - Room clock thermostat
The thermostat’s low insert depth of 20 mm makes it practical for cramped control panels, delivering a full 1 gang digital thermostat without sacrificing performance, so installation in compact automation cabinets is simpler and faster. This reduces retrofit costs and panel redesign while maintaining IP21 protection and CE compliance. Pre-programmed operation and seven switching programs streamline setup, cutting commissioning time and minimizing operator errors in busy production lines. With 230 V AC supply and three-four wired connections, plus a normally open contact rated up to 16 A at 250 V AC, wiring in standard automation cabinets is straightforward and dependable. Standby power of just 0.05 W and external control via EXT connector support energy efficiency and remote management. Saga design elements and a white RAL 9003 finish ensure visual compatibility in modern panels, while dimensions and weight keep enclosure requirements predictable. Compliance with RoHS, REACH, SCIP, and WEEE demonstrates a commitment to sustainable manufacturing and regulatory alignment. These features collectively reduce maintenance downtime, support consistent process temperatures, and enable scalable deployment across multiple panels and lines.
