6.7 External change over signal connection (6.1/6.2)
Terminal 6.1/6.2 (IN1) is an input for potential-free contacts. For the standalone variant, only the
change-over signal (CO) 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).
6.8 External timer connection (central unit variant)
The central unit variant allows the operation of an external clock. The external clock can be connected
to terminal 6.1/6.2 (IN1) as well as to the terminal 6.3/6.4 (IN2). When the input is activated by the
timer, the heating zones parametrised for this are switched to night operation.
