The device is fastened using 4 screws. CE mark/Electromagnetic compatibility The ACC controller is compliant with the EU standards on electromagnetic compatibility, while quality and safety are ensured by the CAREL ISO 9001 certified design and production system and by the CE mark on the product. -
Page 8: User Interface
ACC –Anti-sweat controller 2. User interface The status of the controller is displayed using LEDs that are only visible with the cover open. The LEDs indicate: power on; serial connection status; alarm status. To set the operation of the controller, 1 trimmer and 4 dipswitches are available for the main functions, while internal parameters are used to set all the other functions. - Page 9 ACC –Anti-sweat controller If the appliance is used in a manner that is not specified by the manufacturer, the protection featured for the appliance may be compromised and the appliance may be seriously damaged. Avoid assembling the controllers in environments with the following characteristics: relative humidity greater than 90% non-condensing;...

Page 10: Programming The Instruments
ACC –Anti-sweat controller 4. Programming the instruments The instruments are programmed by dipswitches and trimmer, and by setting the internal parameters accessible via programming key or via serial line. The functions that can be set manually are shown in the tables below:... -
Page 11: Accessories
The programming keys PSOPZKEY00 (Figure 5.1.a) and PSOPZKEYA0 (Figure 5.1.b) are used to copy the complete set of parameters relating to the CAREL ACC controller parameters. The keys must be connected to the PROG KEY connector (4 pin AMP) fitted on the controllers, and work even without switching the controller on (see the summary diagram in Figure 5.1.c.). -
Page 12: Description Of The Functions
ACC –Anti-sweat controller 6. Description of the functions Dewpoint calculation The dewpoint is only calculated in Master mode, based on values measured by the humidity and room temperature probes B1 and B2. In Slave mode, the dewpoint is updated via serial by the Master or by the external supervisor and probes B1 and B2 are ignored (the inputs can be disconnected). -
Page 13: Master Management
ACC –Anti-sweat controller Master management In Master configuration, all three probes are required (B1, B2 and B3). The dewpoint is calculated according to the values measured by probes B1 and B2. The output is controlled according to the value read by probe B3. In the event of alarms on probes B1 or B2, the dewpoint value is forced to 99.9. -
Page 14: Overriding The Output
ACC –Anti-sweat controller Overriding the output The output can forced to the desired value required at any time via serial line, irrespective of the value calculated by the controller. This function is temporary and is not saved; it is disabled automatically when the data reception timeout elapses: 10 s if DIP2 ON, 20 min if DIP2 OFF. - Page 15 ACC –Anti-sweat controller The probe fault alarm is generated if the probe is disconnected or short-circuited. In alarm status, the controller output provides one of three possible voltage values, which can be set by parameter: 50% of the maximum output set by parameter;...
