Device for time dependent automatic opening and closing of a radiator valve has a mechanical mechanism for controlling heat output that is easily adjustable and inexpensive

摘要

Time dependent automatic adjustment of the temperature control valve of a radiator using a control device with two rotating adjustment disks (2, 5). The first (2) is fixed with a control valve (1) and is opened from a closed position by the force of a drive element turning it through an angle fixed by the second positioning disk (5). A timer switch controls opening of the valve using the first disk, while the position of the second disk is used to set how far the first disk turns and therefore the valve opens.
