Alpha IP MIOB 230 V, neutral


The OEM Alpha IP Multi-IO Box (MIOB) serves for the functional extension of the Alpha IP indoor environment solution for surface heating.

This extension can increase the energy efficiency and the comfort, but also the safety of the room-by-room temperature control system. The MIOB offers several connection options for the demand-oriented and energy-efficient operation of pumps and boilers, for the change-over between heating and cooling operation, for dew point monitoring, dehumidifier control, and overtemperature limitation in the overall system.

Installation is performed flexibly and freely placeable on the wall by screws or on DIN rail.
