DC1 FCU Controller              Download PDF



The DC1 is a full featured FCU controller. The DC1 will operate "stand alone" or as an integral part of a building management system (BMS). The control parameters, such as damper stroke time, can be set by the BMS and are stored in non volatile memory (EEPROM) to prevent them from being lost when the power is removed. All connections to the DC1 are by means of plug-in screw terminal connectors which provides for quick, convenient installation, commissioning and maintenance. The heater current valve can optionally be upgraded to a 3kW capacity by means of a larger external heatsink.
