Siemens heating controller POL638.00/DH1 POL638.70/DH1

Siemens POL638.00/DH1 POL638.70/DH1 can construct a regional heating station with up to four heating circuits, three pre regulators, and two domestic hot water circuits by selecting different functional blocks through an intelligent menu.

By selecting different functional blocks through the intelligent menu, the Climatix DH controller can construct a regional heating station with up to four heating circuits, three pre regulators, and two domestic hot water circuits. Function blocks can be flexibly combined to achieve rich applications. To achieve these, specialized tools or programming knowledge are not required. For OEMs, this has high flexibility, shortens development cycles, and saves development costs. The debugging parameter table can be copied between different controllers, saving debugging time.
