Construction

The hatched lines are wires which the qualified personnel must connect to the controller during installation. Connectors of additional
appliances have to pass via two connectors on the boiler backside. The connectors are bi-pole or tri-pole. The tri-pole connector is used
to connect a room thermostat.

Only use battery powered room thermostats!

On the thermostat itself, the connection with an NC (normal closed contact) is used.
