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.
In principle, any on/off room thermostat can be combined with an outdoor sensor.
Upon request of the room thermostat, the boiler will provide heat until the maximum
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 the boiler.
Connect the room outdoor sensor (see par. 10.2).
For the fuel line setting, see the weather dependent regulation (see par. 7.5).
