Use either way:
1. Using 4 core (+ earth)
Relay ------- Vitodens
L ------------- X1/L (left)
N ------------ X1/N (left)
A ------------ X1/L (right)
B ------------ X1/1
or
2. Using 3 core (+ earth)
Relay ----------- Vitodens
L (either) ------- X1/L (left)
N ---------------- X1/N (left)
L (either) link to Relay A
B ---------------- X1/1
In both cases, remove link between L and 1 on the Vitodens (B in wiring diagrams).
