The TCX2 is a programmable universal controller with communication capabilities. Each control loop may use 2 PI sequences
and 6 binary stages. The TCX2 uses the universal X2 operating system. Serial communication options are realized with
Modbus RTU/ASCII and BACnet MS/TP. There is also a Wi-Fi and an Ethernet communication option which supports Modbus
TCP and BACnet IP. An embedded webserver provides a web interface to operate the controller or change the connection
settings. Complete parameter sets may be copied by use of an accessory called AEC-PM1 or exchanged with a PC using an
RS485-USB converter, Wi-Fi or Ethernet communication and the EasySet program.
Functions
• 4 universally configurable control loops:
o Functions for dehumidifying, set point shift and cascade control
o Multiple auxiliary functions: heat-cool auto changeover, automatic enable, set point compensation
o Free heating and cooling with economizer function based on enthalpy or temperature
o Differential, averaging, min and max functions, enthalpy and dew point calculations
o Transmitter function for inputs and set points
• 8 selectable universal inputs (VDC, mA, NTC)
• 3 universal analog outputs (VDC, mA) and 6 relays with each a normally open contact (SPST)
• 8 freely assigned alarm conditions, selectable state of outputs on alarm condition
• Power cap protected real-time clock with 48hr power backup
• 7-day programmable schedules, with options including change of set points and direct position of manual outputs
• Password protected programmable user and control parameters
• Peer to peer communication to optional X2 operation terminal OPxx-VC
• Communication over Modbus, BACnet, Ethernet or Wi-Fi (optional interface required)
• Webserver that supports TCX2 operation trough mobile devices or EasySet IP access (Ethernet or Wi-Fi interface
required)
