Internal coils
Water preheating coil
By preheating the outdoor air, it is possible to prevent
moisture precipitation in the AHU’s outdoor air filter, to
reduce the risk of frosting in the heat exchanger and
to eliminate the risk that pressure sensors and mo-
tor control systems are operating in too low ambient
temperature. The setpoint is of the exhaust air temper-
ature.
Setting Settings range Factory setting
Setpoint -9,9...99,9 °C 1,0 °C
Electrical preheating coil
By preheating the outdoor air, it is possible to prevent
moisture precipitation in the outdoor air fi lter of the air
handling unit, to reduce the risk of frosting in the heat
exchanger and to eliminate the risk that the ambient
temperature will drop lower than minimum permis-
sible. The electrical preheating coil is installed and
configured in factory. The electrical preheating coil
will always have its separate power supply and main
switch.

Electrical postheating coil
The electrical postheating coil is installed and config-
ured in factory. The electrical postheating coil will al-
ways have its separate power supply and main switch.
The capacity of the coil will be controlled proportion-
ally in order to keep a temperature as defined by the
selected operating mode.

Water postheating coil
The water postheating coil is installed and configured
in factory. The 3-way valve is not installed and 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 output O.R.3 on the optional “SAT3”
output relay, is activated whenever heating is desired.
