Wall-mounted Controller and Sensor TRI2-FU
The TRI2 is a programmable controller and sensor with communication capabilities. Each control loop may use 2 PI
sequences and 2 binary stages. The TRI2 uses the universal X2 operating system. Serial communication options are
realized with Modbus RTU/ASCII and BACnet MS/TP over RS485. There is also a Wi-Fi communication option available
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-PM2 or
exchanged with a PC using an RS485-USB converter or Wi-Fi communication, the EasySet program and the configuration
adapter called AEC-TRI-2.
Applications
•Ventilation control
•Temperature control
•Zone control
•Air humidifier and dehumidifier
Functions
•Two universally configurable control loops:
oFunctions for dehumidifying, set point shift and cascade control
oMultiple auxiliary functions: heat-cool auto changeover, automatic enable, set point compensation
oFree heating and cooling with economizer function based on enthalpy or temperature
oDifferential, averaging, min and max functions, enthalpy and dew point calculations
oTransmitter function for inputs and set points
•Built in humidity and temperature sensors
•2 passive inputs (NTC, open contact), 1 analog input (VDC) and 2 analog outputs (VDC)
•2 relays with each a normally open contact (SPST NO) to switch line voltage
•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
•Measures temperature and humidity
•Communication over Modbus, BACnet or Wi-Fi (optional interface required)
•Webserver that supports TRI2 operation trough browser or mobile devices (Wi-Fi interface required)
