  • Page 2: Control Functions

    TCY-T0121 Intellige nt Compact Controller Control Functions The compact controller TCY operates with four different control modules. These modules can be activated and parameterized according to the application to be controlled. The main modules are: Temperature PI, Temperature On/Off, Universal PI and Universal On/Off. All modules operate simultaneously. In order to use the controller, at least one control module must be enabled.

  • Page 3: Input Configuration

    TCY-T0121 Intellige nt Compact Controller Universal Control Mode Cascade control Instead of using a setpoint as the control target, we can use the output of the temperature control loop as setpoint. This is for example used for VAV controllers. Enable 1U-00 to activate cascade control.
  • Page 4 TCY-T0121 Intellige nt Compact Controller Analog Inputs: The analog input signals may be configured with jumpers to 0-10V, 0-5V and 4-20 mA. The jumpers are located just behind the terminal connector of each input. The drawings below indicate the jumper placement for each signal type.
