6.6 Humidity sensor connection (6.3/6.4)

Terminal 6.3/6.4 (IN2) is an input for potential-free contacts. For the standalone variant, only the hu-
midity sensor is connected. If the Alpha IP Access Point is operated using the Alpha IP app, the terminal
can also be used for temperature limiters (TL) or as external clock (ECO). A Homematic CCU 2 allows to
control all inputs and outputs individually.
Humidity sensors (to be provided by the customer) serve for dewing protection in the cooling mode.
