General description 

The TCY-MT-U is a stand-alone electronic temperature controller with 

one control loop. It may use up to 2 PI-sequences. The TCY-MT-U 

features one internal NTC temperature sensor, up to two external sensor 

inputs and up to two analog outputs. The configuration has been 

reduced to a minimum to allow for simple and off-the-shelve usage. For 

more advanced features and current inputs and outputs the TCI product 

range is recommended. The TCY-MT-U can be configured using the 
standard operation terminal. No special tool or software is required.
