4.3 Function of the A/C unit
4.2 Intended use
This A/C unit is used to control room temperature and air humidity. The A/C unit is designed for indoor installation.
Any use beyond this is not deemed to be use as intended.
The A/C unit is exclusively operated by the controller in the front panel and the main switch in the electric box.
In the air inlet a temperature/humidity sensor is located which provides the measured values for the temperature/hu-
midity control. The cooling is achieved by compressor operation in the refrigerant circuit.
The A/C unit control is effected by the on board I/O controller. The operational conception is designed such as to
allow to control up to 19 units from one unit. These units can be installed separately with a maximum control line
length of 1000 m.
Dehumidification
A dehumidification is achieved by a reduction of the air flow. With a constant cooling capacity, the temperature of
the air which flows through the heat exchanger coil, passes below the dew point. The moisture contained in the air
condenses on the heat exchanger gathers in the condensate pan and is carried away by the drain.
