A maximum of seven base stations can be interconnected via the system BUS (syBUS) in order to
exchange global system parameters. After completing the wiring, the base stations must be paired
– see section 4.2 For a line diameter <6 mm, a strain relief must be provided by the customer.
Note! The base stations can also be connected via radio, see section 4.2. A mix of both variants is
possible.

Connection of a customer-supplied temperature limiter (1). This device switches off the pump and
sets the input to TL if too high flow temperatures for the floor heating are detected. If the TL input
is switched, the base station shuts down all actuators automatically.
