Outdoor temperature sensor
The unit is provided with a connection for an outdoor temperature sensor. The
outdoor temperature sensor should be used in combination with an on/off room
thermostat.

set temperature in the boiler has been reached. This maximum set temperature is
automatically regulated via the outdoor sensor, in accordance with the set fuel line in
