The valve cluster uses a two wire bus for the inter communication between the Master and the Slave
valves. The valves are connected in a daisy chain and the bus must be terminated on both sides by a
120Ω resistor that can be set in the link adapter of the valve (refer to chapter «4.5.8.1 Link adapter»).
