SCC2-CQ - Air quality controller
Controller and sensor (X2 OS) for CO2 and Air Quality
The SCC2 is a programmable controller and sensor with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages. The SCC2 comes with a built in RS485 communication interface that allows peer to peer communication with an operation terminal such as OPT1-(2TH)-VC.
Communication plug-in allow for integration of the controller into a network. These modules are described in their own manual. Currently available are plug-ins for BACnet and MODBUS.
Flexible application configuration is made with a parameter-setting routine using the standard operation terminal.
Complete parameter sets may be copied by use of an accessory called AEC-PM2 or exchanged with a PC using an RS485-USB converter and the EasySet program.
Applications
- Ventilation control
- Air measurement
- Zone control
- VAV control
Features
- Two universally configurable control loops:
- Functions for dehumidifying, set point shift and cascade control
- Multiple auxiliary functions: heat-cool auto changeover, automatic enable, set point compensation
- Free heating and cooling with economizer function based on enthalpy or temperature
- Differential, averaging, min and max functions, enthalpy and dew point calculations
- Transmitter function for inputs and set points
- Universal analog outputs (VDC, mA) and one relay with a normally open and a normally closed contact (SPDT)
- 8 freely assigned alarm conditions, selectable state of outputs on alarm condition
- Password protected programmable user and control parameters
- Measures CO2 and VOC
