Universal Fancoil Controller TC57A01KNX is a DIN rail EIB/KNX actuator with three 0-10 V outputs and three 16A relays.

Two 0-10V outputs are used to control proportional valves, while variable speed is controlled with a third. However, a third 0-10 V output can also be configured as an input. If the relays are not used for variable speed control, they can be used to activate any kind of load. A 0-10 V or 4-20 mA signal input is also available for connecting external probes.

In addition, this device has five digital inputs as well as 2 NTC temperature probe inputs. With an internal 2-stage PI algorithm, the device logic can control 2/4 fan coil units.

This device is perfect choice for systems that require separate control differentials, ventilation and logic for energy savings.
