>> Mixing valve running time
B Set the run time that is indicated on the mixing valve
and indicate value in number of minutes.
In the event of Yes on Air handling unit in circuit and
output type Op/Cl:
B Indicate the double value compared with what is
specified on the mixing valve.
>> Mixing valve fully closed
B Set how many K ( °C) below the maximum permitted
flow temperature T1 the mixing valve is to be fully
closed. The maximum flow temperature is different
depending on the type of heating system (radiator or
underfloor). With an underfloor system, the mixing
valve should be fully closed at 45 °C-2K=43 °C (with
factory settings).
>> Mixing valve start closing
B Set how many K ( °C) below the value for fully closed
mixing valve the closure of the mixing valve should
begin. The result is 43 °C-2K=41 °C (with the factory
settings for underfloor heating).
>> Connected to output type
B Select how the mixing valve is controlled. Op/Cl
means control via an Open/Close signal.
A mixing valve of the Op/Cl type is calibrated once
every 24 hours. The mixing valve closes fully during a
run time.
Exception is when Yes has been selected in Air
handling unit in circuit to ensure the flow over the
circuit.
> Air handling unit in circuit
B Select Yes when such a unit exists in the circuit.

Tab. 84 Mixing valve running time
If there is no time indication on the mixing
valve, run it manually ( Chapter 16.6.7)
and measure how long it takes to go from
fully closed to a fully open mixing valve (the
mixing valve stops sounding and the
endposition switch switches off).
