Fröling Hydraulic Module for S3200/P3200/H3200

as a wall-mounted housing with a control board for controlling 2 pumps using 6 sensors. In addition, 2 immersion sensors are included, which can be used for the following purposes: - Buffer tank management for controlled buffer charging via 2 sensors, whereby the heating circuit pumps are enabled by the upper buffer sensor. - Differential temperature control for boilers for speed-controlled regulation of the boiler charging pump; the pump is regulated depending on the buffer tank temperature or the difference to the boiler temperature. - for feeder pumps or solar systems Communication with the boiler control system takes place via a bus cable and can be extended to up to 7 hydraulic modules.
