You choose how you want to operate your Harol roll-up grille: manual or electric.
Different operating methods
Electric using a tubular motor (built into the roller shaft) or via an external block motor. These motors have a thermal cut-out and end-of-run switch so that the roll-up grille stops automatically at the top and bottom. You can choose a turn switch, push button switch or key switch for the control. You can also opt for various home automation systems: o Push button switch o Remote control with transmitter and receiver o Key contact o Keypad code contact
Manual using a coiled spring. You can use this operating system for a roll-up grille with a maximum surface area of 5 m².
