professional planning of an e

5.3. TERRA AL Twin with Hygienik with layer seperate plate
The Hygienik with layer seperate plate is used for hot
water supply and heating water storage.
TERRA AL 17 and 24 Twin could be used in com-
bination with a Hygienik with layer seperate plate.
The TERRA AL 32 Twin schould be installed with two
seperate tanks, one heating buffer and one Hygienik
without layer seperate plate.
In the heating return the included
fl
ow switch must be
installed before the heat pump.
One heating circuit can be regulated as standard. For 2 or more heating circuits an appropriate
additional control-module has to be installed.
