6.5 Pump connection (5.1/5.2/5.3)
Terminal 5.1/5.2/5.3 is a switching relay as potential-free change-over switch. For the standalone var-
iant, only the pump is connected. If the DITECH Smart Home iL central unit is operated using the
DITECH Smart Home iL app, the terminal can also be used for air humidity sensors or for the CO pilot.
(see fig. 4 page 3)
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 DITECH Smart Home iL central unit is operated using the DITECH
Smart Home iL 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.
As soon as the humidity sensor is triggered, the blue C/O LED of the MIOB and the symbol
in the room control unit LCD flash. The pump switches off and all FAL drives are closed.
