Water post heating
The external post heating coil is delivered seperately
from the air handling unit and will not be pre config-
ured in factory. Both the coil and the 3-way valve will
have to be installed and wired on site. The capacity
of the coil will be controlled proportionally in order to
keep a temperature as defined by the selected oper-
ating mode. The reaction speed can be set. A higher
Setting will result in a faster reaction speed; a lower
Setting will result in a slower reaction speed.
