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

The interface uses OpenTherm to communicate with the boiler control
unit. To make this possible, the OTm connection must be connected to the
OpenTherm input of the boiler control unit.OTm
A choice can be made with this control between control based on temper­
ature or heat output. The two controls are described briefly below.
