SDC2-THCQ - Duct Mounted

#

Duct mounted Controller and Sensor (X2 OS) for Temperature, Humidity, CO2 and Air Quality

The SDC2 is a programmable controller and sensor with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages. The SDC2 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 temperature, humidity, CO2 and VOC
