The output signals DC 0…10V can be inverted by means of DIP switch 4  
(see section 4.7.3). 
 
 
To ensure a minimum or maximum supply air volume, the output signal for the air 
flow (DC 0...10V or 3-position) can be limited to a minimum value via parameter 
P63 and to a maximum value via parameter P64.  
Both values can be set between 0% and 100%.

The water temperature acquired by the changeover sensor (QAH11.1 + ARG86.3) 
is used to change over from heating to cooling mode and vice-versa. When the 
water temperature is above 28 °C (parameter P37), the thermostat changes over to 
heating mode, and to cooling mode when below 16 °C (parameter P36).  
If the water temperature is between the 2 changeover points immediately after 
power-up, the thermostat starts in heating mode.  
The water temperature is acquired at 30-second intervals and the operating state is 
updated accordingly.
