SIEMENS RVD255/109-A Equithermal controller

Replacement for RVD235/109-C

SIEMENS RVD255/109-A Equithermal controller
Exchanger station regulator with heating circuit and preparation of TV with storage tank or flow heating. 28 hydraulic applications. LPB and M-Bus communication.

RVD controllers are application controllers designed for compact object transfer stations.
The heating circuits are controlled equithermally according to the time program with the possibility of room temperature influence.
TV preparation is ensured by flow through a plate heat exchanger or by a charging pump in an indirectly heated reservoir.
With the central heat exchanger, the temperature is controlled according to the highest demand of the consumers, which guarantees economical and stable operation of the heat exchanger.

Advantages:
A number of pre-programmed standard applications.
Parameter settings are graded into three levels according to the focus of the parameters (user, service, protection parameters).
Simple creation of larger units by connecting controllers after communication.
