The 0–10 V signal controls the boiler supply temperature. This control
modulates on the basis of flow temperature. The output varies between
the minimum and maximum value on the basis of the flow temperature set
point calculated by the controller.
A jumper (2) on the interface is used to select either temperature-based
control ( ) or output-based control (%).

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 (%).
