5. Connection
Power is supplied via L and N (see technical data); the
connection to the boiler is made via a relay contact.
!
Secure device (8119200 + 8120200) with an upstream
type B or type C circuit breaker (EN 60898-1) with a
maximum of 10 A.
!
The external input is active, therefore do not use exter-
nal voltage. The connected contact must be floating.
At 8120200, the input is not safely separated from the
mains, therefore only connect insulated components.
!
Disconnect the boiler from mains supply before connect-
ing the thermostat.
!
In order to eliminate the possibility of EMC interference,
always lay the mains supply feed separate from the
external input (if one is being used).
!
Faulty connections will damage the device.
