Caution

If you choose to switch off hot water production during the vacation “peri-
odic increases" (preventing bacterial growth) are blocked during this time.
"periodic increases" started in conjunction with the vacation setting being
completed.

Caution

If the exhaust air temperature falls below 16 °C, the compressor is blocked
and the electrical addition is permitted to intervene. When the compressor
is blocked heat is not recovered from the exhaust air.
