KELOX rm thermstats - KM690D Digital-Standard/ KM690U Digital-Cntrl The KELOX rm thermstats are high-quality rm temperature cntrllers fr recrding and cntrlling the required rm temperature fr a maximum user cmfrt. The KELOX digital rm thermstats are available fr 230 V perating vltages. Easy individual rm cntrl is already pssible with the directly cnnected actuatrs. In cnjunctin with the KM691 KELOX cnnectin unit, a perfectly crdinated verall system is realisable fr surface temperature cntrl. The setting f the required rm temperature and the peratin takes place using the rtary knb with push-turn mechanics and sft click. The symbls are always shwn distinctly with the clearly laid ut, language-neutral indicatr f the high-quality display. In rder t satisfy the desired requirements, varius versins are available.
