TERRA SWM HGL P for active cooling and with Hygienik 2.0 for domestic hot water preparation
The heat pump manages next to the Hygienik 2.0 an additional cooling buffer.
In this scheme, there are two valves that switch the
fl
ow and return of the heat pump between Hygienik and
the cooling storage.
An additional valve will be used for switching between the heating circuit and the cooling circuit. The heat pump
operates in process reversal and cools the cooling buffer to the desired temperature.

Attention!
-Mount the dew point switch on a suitable location.
• In cooling mode a dew point control via a roomstat (room sensor) and a dew point switch or
humidity sensor is necessary!
•
During cooling mode of the heat pump it is not possible to load the upper area of the Hygienik.
