The HERZ actuating drive is an electrothermal actuator for 2-point control in heating and cooling systems that is installed in combination with a temperature controller. Exceptionally well suited for zone control and floor heating. The HERZ actuating drive can be combined with all HERZ valves with connection threads M28 x 1.5 or M30 x 1.5 that are configured for thermostatic operation. The version with auxiliary contact additionally enables signaling of the switch position or to switch another electrical device. At direct voltage of 4…30 V the switching capacity is 1…100 mA, 1 A, 48 V=. The electric circuits at the auxiliary contact and at the drive must have the same phase. It is not permissible to apply 400 V ~ to the 4 x 0,5 mm² cable. It is not permissible to connect this cable to differing circuits such as extra-low voltage or low voltage circuits. The actuating cam in the drive must be engaged before mounting the connector plug. This actuating cam can no longer be removed. However, it is still possible to subsequently mount a 2-point connector plug if necessary.
