Weishaupt heating control system RVA53

The digital controller WRD 0.2 (order no. 660 159) can no longer be supplied due to component discontinuation. The RVA 53 digital controller for WRD 0.2 has been added to the delivery programme as a replacement controller. The controller can be inserted into the cut-out in the boiler control on WTU. The digital controller set includes the required adapter cable, detailed installation instructions and the manufacturer's basic documentation. The QAA 50 and QAA 70 digital room units can continue to be used. It is possible to connect only one QAA 50 or QAA 70. Communication with the QAA 35 is not possible. If necessary, this room unit must be replaced by a QAA 50/70 in the corresponding slot.
