TRI2-FA-TH-221.202C

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
