How does THERMA V Work?
3
Water
Inlet
1
When the refrigerant is passed across the
heat exchanger the liquid refrigerant retrieve
the heat from air and evaporates.
2
The vapor refrigerant flow into compressor
and is compressed. In the compressing stage
the pressure is increased and the temperature
is raised sharply, generating heat.
3
The liquid refrigerant passes through
expansion valve in outdoor unit is ready to
start whole cycle again.

Weather-dependent Operation
This mode is only applied to heating.
In order to save energy and to give highest comfort, setting temperature will follow outside temperature.
If outdoor temperature decreases, heating capacity for the house will increase automatically in order to keep same room
temperature. All parameters will be set by installer during start-up procedure and will be adapted to the site characteristic.
