Viessmann VITOCAL 300, Installation And Service Instructions Manual

Page: 93 / 160

This setting determines whether the
heat pump plus the electric heater are
to be used for drying the building.
Set this function to "
NO " if the heat
pump is not ready for use, for example
because the primary heat pump circuit
is not yet completed at the time the
building is to be dried out.
Note
When using a heat pump for drying
buildings there is a risk that the pri-
mary side will become overloaded.
This can lead to
permanent damage
to the ground probes/collectors.

Setting of the number of days that the

OFF.
The remaining days for drying build-
ings will be shown on the display
when the programming unit flap is
