DDFCUC Fan Coil Unit Controller
Direct control of air conditioning
The Philips Dynalite DDFCUC is a fan coil unit controller, designed for direct
connection to components commonly found in heating, ventilation, and air
conditioning (HVAC) systems with fan coil units (FCU).
0-10 V and TRIAC (0-24 V) valve outputs
– Provided for control of hot and cold
water valves.
0-10 V fan output – Silent, accurate
speed signal control of compatible fans.
1 to 3-speed fan output – Switched
control of LOW/MED/HIGH fan settings.
GPR (General Purpose Relay) – Provided
for use with electrical heaters or power
outlet switching via an external contactor.
Suitable for non-seasonal two-pipe
systems - Refer to the easy-to-follow
DDFCUC Installation Instructions and
DDFCUC Commissioning Guide for more
information.
Configurable inputs – For use with
peripheral devices including smoke
detector, motion detector, window open/
close sensor, airflow detector, drip tray
overflow, dirty air filter, and hot water on
cold valve. Supports 0-10 V, dry contact,
and 20 kΩ NTC sources.
0-10V valve position feedback – With
compatible valves, INPUT1 and INPUT2
can capture position feedback for control
outputs VALVE1 and VALVE2 respectively.
Resistive or networked temperature
sensors – Allows the device to use data
from a local temperature sensor, or
networked temperature sensor such as an
Antumbra or Revolution user interface.
Networkable – Can be networked
with other Dynalite equipment via the
onboard RS-485 DyNet port.
