8.4.1 Connection status (Nc)

If the boiler locks out, a relay is de-energised and the alarm can
be transmitted via a potential-free contact
(maximum 230 V, 1 A) on terminals Nc and C of terminal strip X4.

8.4.2 OTm connection

The interface uses OpenTherm to communicate with the boiler
control. The OTm connection on terminal strip X5 must therefore
be connected to the OpenTherm OT input of the boiler control.
