The 0–10 V signal controls the boiler output. This control modulates on the
basis of the heat output. The minimum output is linked to the boiler's
modulation depth. The output varies between the minimum and maximum
value on the basis of the value defined by the controller.
Analogue output (0–10 V)
This feedback can be based on temperature or heat output. The two
controls are described briefly below.
A jumper (1) on the interface is used to select either temperature ( ) or
output (%).

5.3.22 Connecting a PC/laptop
There is a Service connector next to the control panel. A Recom interface
can be used to connect a PC, laptop or a Smart Service Tool here. Using
the Recom PC/laptop service software, you can enter, change and read
out various boiler settings.
Connecting an interface connector:
1. Move the Service connector slide upwards.
2. Push the interface connector into place. It should snap shut with a
click.
Disconnect the interface connector again:
3. Maintain slight tension on the interface connector
4. Push the slide downwards. The interface connector will now be
released.
5. Pull the interface connector from the connector.
