Wall-mounted Controller and Sensor

The TRI2 is a programmable controller and sensor with communication capabilities. Each control loop may use 2 PI sequences and 2 binary stages.

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, the EasySet program and the configuration adapter called AEC-TRI.

Applications

  • Ventilation control
  • Tempearture control
  • Zone control
  • Air humidifier and dehumidifier

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
  • 2 passive inputs (NTC, open contact), 1 analog input (VDC) and 2 analog outputs (VDC)
  • 2 relays with each a normally open contact 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
