Description
The EFCB-OE1 Series Networkable Fan Coil Controller,
and TFL24 and TDU Series LCD Thermostats are designed
for simple and accurate control of any fan coil application.
The Networkable 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.
