Defining the control type
The product can specify either a target output value or a target
flow temperature value. A target flow temperature value is
specified in the as-supplied state (plug X1 plugged in).
> Fig. 1.3 To specify a target output value, remove plug X1
with the cable bridge from slot X1.
The maximum and minimum flow temperature depend on the
setting on the heat generator. We recommend setting the heat
generator's target flow temperature to the maximum.
