ReCooler HP
The ReCooler HP is an integrated reversible cooler.
Depending if the air handling unit is in heating or cooling
demand the ReCooler HP will alter between cooling and
heating mode.

Under some conditions the ReCooler HP will go to a defrost
mode during a couple of minute. During this time the
fans will go on reduced speed. This reduced fan speed
is configurable for each fan. The settings are 20-100 % of
