Description
The EFCB Series Networkable Fan Coil Controller, and
TFL24 and TDF Series Digital Room Sensors are designed
for simple and accurate control of any fan coil application. The
BACnet Fan Coil Controller is mounted inside the fan coil
cabinet and incorporates a configurable fan coil algorithm,
variable three speed fan control and either modulating or
digital heating and cooling outputs. All inputs and high/low
voltage outputs are centralized at the control module in the
fan coil cabinet.
