The ECC-PFCUs control the space temperature for equipments with up to 4 stages of cooling or heating, 2 floating valves and up to 3 fan speeds and offers complete humidity control including a dehumidification cycle.
The powered fan coil unit controllers’ line includes:
the ECC-PFCU, with 6 universal inputs, 4 high voltage relay outputs and 4 triac outputs
the ECC-PFCU-A, featuring 2 additional analog outputs and 24 VAC power supply
the wireless communication enabled ECC-PFCU-W and ECC-PFCU-AW.
The ECC-PCFUs can be powered by supply ranging from 85 to 265 VAC, with no external transformer required, thus requiring no additional wiring. Additionally, relay outputs supply up to 277 VAC and triac outputs up to 265 VAC power switching, allowing for application options ranging from 24 VAC valve to 277 VAC lighting control. With 6 high precision (16 bit A/D) universal inputs, the ECC-PFCUs support digital, voltage (0-10V), thermistor (PT100, 1K, 10K, 100K) inputs and current from 4-20 mA with external resistor. Further expanding the controller’s versatility, the spare I/O points can be shared over the network.
The ECC-PFCUs can be configured by using the LNS based EC-Configure plug-in or EC-Net AX wizard, for integration into the Niagara Framework. These configuration interfaces, provided free of charge, simplify configuration and sequencing methods by prompting the user for the necessary configuration data. Additionally, the equipment based control configuration enables one to extend the control logic to other outputs, such as to remote I/O modules, in fact doubling the amount of physical outputs which can be controlled by one ECC-PFCU.
The ECC-PFCU-W and the ECC-PFCUA-W, with an on-board wireless receiver provides support for a variety of wireless, battery-less sensors, switches and other devices. The wireless, battery-less peripherals are easy to install, highly adaptable and have no limitations as to the building materials they can be mounted to.
Distech Controls also offers the EC-Smart-Sensor-FC, a communicating LCD Sensor for use with the ECC-PFCU products, providing monitoring of room temperature, setpoint adjustment and override and a fan speed command.
