General description 
The TCY3 is a stand-alone electronic universal controller with two autonomous control loops. Each control loop may use up 
to 2 PID sequences. The TCY3-T1102 features 1 NTC temperature sensor and 1 analog input, 1 binary input and 1 analog 
output. The outputs need to be assigned to the control sequences by parameters. A detailed configuration is possible by 
following a simple setup routine. The TCY3 can be configured using the standard operation terminal. No special tool or 
software is required.
