Function overview
When assigning relays with functions, the activated function for already used relays must first be deactivated before a new
function can be selected.
Mixer
This menu contains all settings relating to the mixer of the heating circuit.
Direction
Direction of the mixing valve can be set here.
Mixer turn time
The mixer is switched on i.e. is opening or closing for the time span set here, then the temperature is measured to control the flow tem-
perature
Mixer off factor
The calculated pause time of the mixer is multiplied with the value set here. If the pause factor is ‚1‘, the normal pause time is used,
‚0.5‘ will use half the normal pause time. Setting the pause factor to ‚4‘ would quadruple the pause time.
Mixer increase
If the temperature rises very fast, this value is added to the measured flow temperature so that the mixer’s reaction is stronger. If the
measured temperature does not rise any more, the measured value is used again. The measurement occurs once every minute.
Mixer run time
Mixer-specific setting of the running time required by the mixer for a full ride.
Signal type
Only available, if the function is used on one of the V-outputs. The type of device to be controlled is set here.
0-10V: Control by 0-10V signal.
PWM: Control by means of a PWM signal.
Cooling valve Heating circuit 1/ Heating circuit 2
If the heating circuit is in heating-off, cooling-off, heating-eco, heating-normal or heating-comfort mode, the relay is switched off or
switched to the heating circuit buffer.
If the heating circuit is in cooling-Eco, cooling-normal or cooling-Comfort mode, the relay is switched on or the valve switches to the
cooling circuit.
The additional function cooling valve heating circuit 1 / heating circuit 2 is only visible if heating circuit 1 / 2 has been activ-
ated on an output.
Heating Circuit 2
See " Heating Circuit (X) " on page 32
Free Cooling
If the function is activated, the output switches a pump or fan and supplies the heating system with "free cooling". This pump supplies
e.g. heating circuits whose cooling valve is switched on and must therefore run as soon as cooling is required in at least one heating
circuit.
Switch-on condition: a heating circuit is set to Cooling-Eco, Cooling-Normal or Cooling-Turbo.
Switch-off condition: no heating circuit cools.
RFI mixer
The RLA-mixer function (return flow increase mixer) can be used to control a motorized return flow increase for a solid fuel boiler or a
return flow buffer/buffer admixture. The RFI mixer requires either 2 relay switch outputs (230) or alternatively may be controlled via a 0-
10V / PWM output (PWM mixer).
