TCY-FT - Floating


Thermostat for 3-point floating actuators

The TCY-FT is a stand-alone electronic universal controller with one  temperature control loop for wall mounting. It may use up to two PI sequences. The TCY-FT features one internal NTC temperature sensor, up to two external sensor inputs and up to four binary 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-FT can be configured using the standard operation terminal. No special tool or software is required.
