The flow or return temperature sensor of primary controller type 2 can be used for
display purposes.
By configuring the outputs, it is determined whether primary controller type 1 or 2 is used.
Without configuration of a mixing valve, primary controller type 2 is automatically used.
But a flow temperature increase can also be defined with primary controller type 2 to
compensate for temperature losses in the case of long pipes. For more detailed informa-
tion about flow temperature increase, refer to section 8.7 "Setpoint increase".
8.3.1

Mixing valve control

For control of the mixing valve, a 3-position or DC 0...10 V actuator can be used. The
selection is made by configuring the relevant output.
8.3.2

Pump control

Pump control offers a number of monitoring choices independent of whether the pump
is a single pump or twin pump.
For more detailed information about pump control and twin pumps, refer to section 5.8
"Pump control and twin pumps".
