6.4.15.3 Dehumidifying
The function is intended for dehumidifying the supply air in order
to prevent condensation in the supply air duct or in connected air
conditioning products.
The dehumidification regulation function controls the humidity
in the supply air duct or the extract air duct by means of an air
cooler and an air heater for reheating.
The function requires that an air cooler be mounted upstream of
the air heater in the supply air duct. See the example to the right.
If control of the humidity in the supply air duct is required, install
a TBLZ-1-31-1 humidity sensor in the supply air duct. If control
of the humidity in the extract air duct is required, install a TBLZ-
1-31-2 humidity sensor in the extract air duct and a TBLZ-1-31-1
humidity sensor in the supply air duct. Connect the sensor to the
AHU. See separate installation instructions.
Cooling energy is emitted to condense the moisture in the supply
airflow, which then is heated to the desired supply air tempera-
ture. This causes a reduction in the moisture content of the
supply air.
The cooling unit used must be sized so that the temperature of
the supply air will be below the dew point, otherwise no conden-
sation will arise and no dehumidification will occur.

Closed circuit involves closing the circuit in order to initiate an
alarm. Open circuit involves opening the circuit in order to initi-
ate an alarm. Contactor function involves the use of an auxiliary
contact from a contactor, which controls the humidifier. The aux.
contact is connected to the alarm input.
