5.5. TERRA AL Twin with Hygienik with layer seperate plate and cooling buffer
The TERRA AL Twin heatpump is able to work in cooling mode too. For every type of cooling system a cooling
buffer is needed.
For safety reasons an air humidity sensor resp. a dew point sensor has to be installed to monitor the dew point.
In the heating return the included
fl
ow switch must be installed before the heat pump.
If the TERRA AL Twin has to work also in cooling mode, a cooling buffer has to be integrated.
An air humidity sensor resp. a dew point sensor has to be installed to monitor the dew point.
